+To enable sign-in for users with a LinkedIn account in Azure Active Directory B2C (Azure AD B2C), you need to create an application in [LinkedIn Developers website](https://developer.linkedin.com/). If you don't already have a LinkedIn account, you can sign up at [https://www.linkedin.com/](https://www.linkedin.com/).

+1. By default, your LinkedIn app isn't approved for scopes related to sign in. To request a review, select the **Products** tab, and then select **Sign In with LinkedIn using OpenID Connect**. When the review is complete, the required scopes will be added to your application.

+1. On the **Portal settings | Directories + subscriptions** page, find your Azure AD B2C directory in the **Directory name** list, and then select **Switch**.

+1. Select **Identity providers**, then select **New OpenID Connect provider**.

+1. Enter a **Name**. For example, *LinkedIn-OIDC*.

+1. For the **Metadata URL**, enter **https://www.linkedin.com/oauth/.well-known/openid-configuration**.

+ Title: Tutorial to configure Azure Active Directory B2C with Transmit Security

+description: Learn how to configure Azure Active Directory B2C with Transmit Security for risk detect.

+zone_pivot_groups: b2c-policy-type

+# Customer intent: As a developer integrating Transmit Security with Azure AD B2C for risk detect. I want to configure a custom poicy with Transmit Security and set it up in Azure AD B2C, so I can detect and remidiate risks by using multi-factor authentication.

+# Configure Transmit Security with Azure Active Directory B2C for risk detection and prevention

+In this tutorial, learn to integrate Azure Active Directory B2C (Azure AD B2C) authentication with [Transmit Security's Detection and Response Services (DRS)](https://transmitsecurity.com/platform/detection-and-response). Transmit Security allows you to detect risk in customer interactions on digital channels, and to enable informed identity and trust decisions across the consumer experience.

+## Scenario description

+A Transmit Detection and Response integration includes the following components:

+- **Azure AD B2C tenant**: Authenticates the user and hosts a script that collects device information as users execute a target policy. It blocks or challenges sign-in/up attempts based on the risk recommendation returned by Transmit.

+- **Custom UI templates**: Customizes HTML content of the pages rendered by Azure AD B2C. These pages include the JavaScript snippets required for Transmit risk detection.

+- **Transmit data collection service**: Dynamically embedded script that logs device information, which is used to continuously assess risk during user interactions.

+- **Transmit DRS API endpoint**: Provides the risk recommendation based on collected data. Azure AD B2C communicates with this endpoint using a REST API connector.

+- **Azure Functions**: Your hosted API endpoint that is used to obtain a recommendation from the Transmit DRS API endpoint via the API connector.

+The following architecture diagram illustrates the implementation described in the guide:

+[  ](./media/partner-transmit-security/transmit-security-integration-diagram.png#lightbox)

+1. The user signs-in with Azure AD B2C.

+2. A custom page initializes the Transmit SDK, which starts streaming device information to Transmit.

+3. Azure AD B2C reports a sign-in action event to Transmit in order to obtain an action token.

+4. Transmit returns an action token, and Azure AD B2C proceeds with the user sign-up or sign-in.

+5. After the user signs-in, Azure AD B2C requests a risk recommendation from Transmit via the Azure Function.

+6. The Azure Function sends Transmit the recommendation request with the action token.

+7. Transmit returns a recommendation (challenge/allow/deny) based on the collected device information.

+8. The Azure Function passes the recommendation result to Azure AD B2C to handle accordingly.

+9. Azure AD B2C performs more steps if needed, like multifactor authentication and completes the sign-up or sign-in flow.

+## Prerequisites

+* A Microsoft Entra subscription. If you don't have one, get a [free account](https://azure.microsoft.com/free/)

+* [An Azure AD B2C tenant](./tutorial-create-tenant.md) linked to the Entra subscription

+* [A registered web application](./tutorial-register-applications.md) in your Azure AD B2C tenant

+* [Azure AD B2C custom policies](./tutorial-create-user-flows.md?pivots=b2c-custom-policy)

+* A Transmit Security tenant. Go to [transmitsecurity.com](https://transmitsecurity.com/)

+## Step 1: Create a Transmit app

+Sign in to the [Transmit Admin Portal](https://portal.transmitsecurity.io/) and [create an application](https://developer.transmitsecurity.com/guides/user/create_new_application/):

+1. From **Applications**, select **Add application**.

+1. Configure the application with the following attributes:

+ | Property | Description |

+ |:|:|

+ | **Application name** | Application name|

+ | **Client name** | Client name|

+ | **Redirect URIs** | Enter your website URL. This attribute is a required field but not used for this flow|

+3. Select **Add**.

+4. Upon registration, a **Client ID** and **Client Secret** appear. Record the values for use later.

+## Step 2: Create your custom UI

+Start by integrating Transmit DRS into the B2C frontend application. Create a custom sign-in page that integrates the [Transmit SDK](https://developer.transmitsecurity.com/sdk-ref/platform/introduction/), and replaces the default Azure AD B2C sign-in page.

+Once activated, Transmit DRS starts collecting information for the user interacting with your app. Transmit DRS returns an action token that Azure AD B2C needs for risk recommendation.

+To integrating Transmit DRS into the B2C sign-in page, follow these steps:

+1. Prepare a custom HTML file for your sign-in page based on the [sample templates](./customize-ui-with-html.md#sample-templates). Add the following script to load and initialize the Transmit SDK, and to obtain an action token. The returned action token should be stored in a hidden HTML element (`ts-drs-response` in this example).

+ ```html

+ <!-- Function that obtains an action token -->

+ <script>

+ function fill_token() {

+ window.tsPlatform.drs.triggerActionEvent("login").then((actionResponse) => {

+ let actionToken = actionResponse.actionToken;

+ document.getElementById("ts-drs-response").value = actionToken;

+ console.log(actionToken);

+ });

+ }

+ </script>

+

+ <!-- Loads DRS SDK -->

+ <script src="https://platform-websdk.transmitsecurity.io/platform-websdk/latest/ts-platform-websdk.js" defer> </script>

+

+ <!-- Upon page load, initializes DRS SDK and calls the fill_token function -->

+ <script defer>

+ window.onload = function() {

+ if (window.tsPlatform) {

+ // Client ID found in the app settings in Transmit Admin portal

+ window.tsPlatform.initialize({ clientId: "[clientId]" });

+ console.log("Transmit Security platform initialized");

+ fill_token();

+ } else {/

+ console.error("Transmit Security platform failed to load");

+ }

+ };

+ </script>

+ ```

+1. [Enable JavaScript and page layout versions in Azure AS B2C](./javascript-and-page-layout.md).

+1. Host the HTML page on a Cross-Origin Resource Sharing (CORS) enabled web endpoint by [creating a storage account](../storage/blobs/storage-blobs-introduction.md) and [adding CORS support for Azure Storage](/rest/api/storageservices/cross-origin-resource-sharing--cors--support-for-the-azure-storage-services).

+## Step 3: Create an Azure Function

+Azure AD B2C can obtain a risk recommendation from Transmit using a [API connector](./add-api-connector.md). Passing this request through an intermediate web API (such as using [Azure Functions](/azure/azure-functions/)) provides more flexibility in your implementation logic.

+Follow these steps to create an Azure function that uses the action token from the frontend application to get a recommendation from the [Transmit DRS endpoint](https://developer.transmitsecurity.com/openapi/risk/recommendations/#operation/getRiskRecommendation).

+1. Create the entry point of your Azure Function, an HTTP-triggered function that processes incoming HTTP requests.

+ ```csharp

+ public static async Task<HttpResponseMessage> Run(HttpRequest req, ILogger log)

+ {

+ // Function code goes here

+ }

+ ```

+2. Extract the action token from the request. Your custom policy defines how to pass the request, in query string parameters or body.

+ ```csharp

+ // Checks for the action token in the query string

+ string actionToken = req.Query["actiontoken"];

+

+ // Checks for the action token in the request body

+ string requestBody = await new StreamReader(req.Body).ReadToEndAsync();

+ dynamic data = JsonConvert.DeserializeObject(requestBody);

+ actionToken = actionToken ?? data?.actiontoken;

+ ```

+3. Validate the action token by checking that the provided value isn't empty or null:

+ ```csharp

+ // Returns an error response if the action token is missing

+ if (string.IsNullOrEmpty(actionToken))

+ {

+ var respContent = new { version = "1.0.0", status = (int)HttpStatusCode.BadRequest, userMessage = "Invalid or missing action token" };

+ var json = JsonConvert.SerializeObject(respContent);

+ log.LogInformation(json);

+ return new HttpResponseMessage(HttpStatusCode.BadRequest)

+ {

+ Content = new StringContent(json, Encoding.UTF8, "application/json")

+ };

+ }

+ ```

+4. Call the Transmit DRS API. The Transmit Client ID and Client Secret obtained in Step 1 should be used to generate bearer tokens for API authorization. Make sure to add the necessary environment variables (like ClientId and ClientSecret) in your `local.settings.json` file.

+ ```csharp

+ HttpClient client = new HttpClient();

+ client.DefaultRequestHeaders.Add("Authorization", $"Bearer {transmitSecurityApiKey}");

+

+ // Add code here that sends this GET request:

+ // https://api.transmitsecurity.io/risk/v1/recommendation?action_token=[YOUR_ACTION_TOKEN]

+

+ HttpResponseMessage response = await client.GetAsync(urlWithActionToken);

+ ```

+5. Process the API response. The following code forwards the API response if successful; otherwise, handles any errors.

+ ```csharp

+ if (response.IsSuccessStatusCode)

+ {

+ log.LogInformation(responseContent);

+ return new HttpResponseMessage(HttpStatusCode.OK)

+ {

+ Content = new StringContent(responseContent, Encoding.UTF8, "application/json")

+ };

+ }

+ else

+ {

+ var errorContent = new { version = "1.0.0", status = (int)response.StatusCode, userMessage = "Error calling Transmit Security API" };

+ var json = JsonConvert.SerializeObject(errorContent);

+ log.LogError(json);

+ return new HttpResponseMessage(response.StatusCode)

+ {

+ Content = new StringContent(json, Encoding.UTF8, "application/json")

+ };

+ }

+ ```

+## Step 4: Configure your custom policies

+You incorporate Transmit DRS into your Azure B2C application by extending your custom policies.

+1. Download the [custom policy starter pack](https://github.com/Azure-Samples/active-directory-b2c-custom-policy-starterpack/archive/master.zip) to get started (see [Create custom policies in Azure AD B2C](./tutorial-create-user-flows.md?pivots=b2c-custom-policy))

+2. Create a new file that inherits from **TrustFrameworkExtensions**, which extens the base policy with tenant-specific customizations for Transmit DRS.

+ ```xml

+ <BasePolicy>

+ <TenantId>YOUR AZURE TENANT</TenantId>

+ <PolicyId>B2C_1A_TrustFrameworkExtensions</PolicyId>

+ </BasePolicy>

+ ```

+2. In the `BuildingBlocks` section, define `actiontoken`, `ts-drs-response`, and `ts-drs-recommendation` as claims:

+ ```xml

+ <BuildingBlocks>

+ <ClaimsSchema>

+ <ClaimType Id="ts-drs-response">

+ <DisplayName>ts-drs-response</DisplayName>

+ <DataType>string</DataType>

+ <UserHelpText>Parameter provided to the DRS service for the response</UserHelpText>

+ <UserInputType>TextBox</UserInputType>

+ </ClaimType>

+ <ClaimType Id="actiontoken">

+ <DisplayName>actiontoken</DisplayName>

+ <DataType>string</DataType>

+ <UserHelpText />

+ <UserInputType>TextBox</UserInputType>

+ </ClaimType>

+ <ClaimType Id="ts-drs-recommendation">

+ <DisplayName>recommendation</DisplayName>

+ <DataType>string</DataType>

+ <UserHelpText />

+ <UserInputType>TextBox</UserInputType>

+ </ClaimType>

+ </ClaimsSchema>

+ <BuildingBlocks>

+ ```

+3. In the `BuildingBlocks` section, add a reference to your custom UI:

+ ```xml

+ <BuildingBlocks>

+ <ClaimsSchema>

+ <!-- your claim schemas-->

+ </ClaimsSchema>

+

+ <ContentDefinitions>

+ <ContentDefinition Id="api.selfasserted">

+ <!-- URL of your hosted custom HTML file-->

+ <LoadUri>YOUR_SIGNIN_PAGE_URL</LoadUri>

+ </ContentDefinition>

+ </ContentDefinitions>

+ </BuildingBlocks>

+ ```

+4. In the `ClaimsProviders` section, configure a claims provider that includes the following technical profiles: one (`SelfAsserted-LocalAccountSignin-Email`) that outputs the action token, and another (`login-DRSCheck` in our example) for the Azure function that receives the action token as input and outputs the risk recommendation.

+ ```xml

+ <ClaimsProviders>

+ <ClaimsProvider>

+ <DisplayName>Sign in using DRS</DisplayName>

+ <TechnicalProfiles>

+ <TechnicalProfile Id="SelfAsserted-LocalAccountSignin-Email">

+ <DisplayName>Local Account Sign-in</DisplayName>

+ <Item Key="setting.showSignupLink">true</Item>

+ <Item Key="setting.showCancelButton">false</Item>

+ <Item Key="ContentDefinitionReferenceId">api.selfasserted</Item>

+ <Item Key="language.button_continue">Sign In</Item>

+ </OutputClaims>

+ <ValidationTechnicalProfiles>

+ <ValidationTechnicalProfile ReferenceId="login-DRSCheck" />

+ <ValidationTechnicalProfile ReferenceId="login-NonInteractive" />

+ </ValidationTechnicalProfiles>

+ </TechnicalProfile>

+ <TechnicalProfile Id="login-DRSCheck">

+ <DisplayName>DRS check to validate the interaction and device </DisplayName>

+ <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.RestfulProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />

+ <Metadata>

+ <!-- Azure Function App -->

+ <Item Key="ServiceUrl">YOUR_FUNCTION_URL</Item>

+ <Item Key="AuthenticationType">None</Item>

+ <Item Key="SendClaimsIn">Body</Item>

+ <!-- JSON, Form, Header, and Query String formats supported -->

+ <Item Key="ClaimsFormat">Body</Item>

+ <!-- Defines format to expect claims returning to B2C -->

+ <!-- REMOVE the following line in production environments -->

+ <Item Key="AllowInsecureAuthInProduction">true</Item>

+ </Metadata>

+ <InputClaims>

+ <!-- Receives the action token value as input -->

+ <InputClaim ClaimTypeReferenceId="ts-drs-response" PartnerClaimType="actiontoken" DefaultValue="0" />

+ </InputClaims>

+ <OutputClaims>

+ <!-- Outputs the risk recommendation value returned by Transmit (via the Azure function) -->

+ <OutputClaim ClaimTypeReferenceId="ts-drs-recommendation" PartnerClaimType="recommendation.type" />

+ </OutputClaims>

+ </TechnicalProfile>

+ </TechnicalProfiles>

+ </ClaimsProvider>

+ </ClaimsProviders>

+ ```

+5. In the `UserJourneys` section, create a new user journey (`SignInDRS` in our example) that identifies the user and performs the appropriate identity protection steps based on the Transmit risk recommendation. For example, the journey can proceed normally if Transmit returns **allow** or **trust**, terminate and inform the user of the issue if 'deny', or trigger a step-up authentication process if **challenge**.

+```xml

+ <UserJourneys>

+ <UserJourney Id="SignInDRS">

+ <OrchestrationSteps>

+ <!-- Step that identifies the user by email and stores the action token -->

+ <OrchestrationStep Order="1" Type="CombinedSignInAndSignUp" ContentDefinitionReferenceId="api.selfasserted">

+ <ClaimsProviderSelections>

+ <ClaimsProviderSelection ValidationClaimsExchangeId="LocalAccountSigninEmailExchange" />

+ </ClaimsProviderSelections>

+ <ClaimsExchanges>

+ <ClaimsExchange Id="LocalAccountSigninEmailExchange" TechnicalProfileReferenceId="SelfAsserted-LocalAccountSignin-Email" />

+ </ClaimsExchanges>

+ </OrchestrationStep>

+ <!-- Step to perform DRS check -->

+ <OrchestrationStep Order="2" Type="ClaimsExchange">

+ <ClaimsExchanges>

+ <ClaimsExchange Id="DRSCheckExchange" TechnicalProfileReferenceId="login-DRSCheck" />

+ </ClaimsExchanges>

+ </OrchestrationStep>

+ <!-- Conditional step for ACCEPT or TRUST -->

+ <OrchestrationStep Order="3" Type="ClaimsExchange">

+ <Preconditions>

+ <Precondition Type="ClaimEquals" ExecuteActionsIf="false">

+ <Value>ts-drs-recommendation</Value>

+ <Value>ACCEPT</Value>

+ <Value>TRUST</Value>

+ <Action>SkipThisOrchestrationStep</Action>

+ </Precondition>

+ </Preconditions>

+ <!-- Define the ClaimsExchange or other actions for ACCEPT or TRUST -->

+ </OrchestrationStep>

+ <!-- Conditional step for CHALLENGE -->

+ <OrchestrationStep Order="4" Type="ClaimsExchange">

+ <Preconditions>

+ <Precondition Type="ClaimEquals" ExecuteActionsIf="false">

+ </Precondition>

+ </Preconditions>

+ <!-- Define the ClaimsExchange or other actions for DENY -->

+ </OrchestrationStep>

+ </UserJourney>

+ </UserJourneys>

+```

+7. Save the policy file as `DRSTrustFrameworkExtensions.xml`.

+8. Create a new file that inherits from the file you saved. It extends the sign-in policy that works as an entry point for the sign-up and sign-in user journeys with Transmit DRS.

+ ```xml

+ <BasePolicy>

+ <TenantId>YOUR AZURE TENANT</TenantId>

+ <PolicyId>B2C_1A_DRSTrustFrameworkExtensions</PolicyId>

+ </BasePolicy>

+ ```

+9. In the `RelyingParty` section, configure your DRS-enhanced user journey (`SignInDRS` in our example).

+ ```xml

+ <RelyingParty>

+ <DefaultUserJourney ReferenceId="SignInDRS" />

+ <UserJourneyBehaviors>

+ <ScriptExecution>Allow</ScriptExecution>

+ </UserJourneyBehaviors>

+ <TechnicalProfile Id="PolicyProfile">

+ <DisplayName>PolicyProfile</DisplayName>

+ <Protocol Name="OpenIdConnect" />

+ <OutputClaims>

+ <OutputClaim ClaimTypeReferenceId="displayName" />

+ <OutputClaim ClaimTypeReferenceId="givenName" />

+ <OutputClaim ClaimTypeReferenceId="surname" />

+ <OutputClaim ClaimTypeReferenceId="email" />

+ <OutputClaim ClaimTypeReferenceId="objectId" PartnerClaimType="sub" />

+ </OutputClaims>

+ <SubjectNamingInfo ClaimType="sub" />

+ </TechnicalProfile>

+ </RelyingParty>

+ ```

+9. Save the policy file as `DRSSignIn.xml`.

+## Step 5: Upload the custom policy

+Using the directory with your Azure AD B2C tenant, upload the custom policy:

+1. Sign in to the [Azure portal](https://portal.azure.com/).

+1. In the portal toolbar, select **Directories + subscriptions**.

+1. On the **Portal settings | Directories + subscriptions** page, in the **Directory name** list, find the Azure AD B2C directory and then select **Switch**.

+1. Under **Policies**, select **Identity Experience Framework**.

+1. Select **Upload Custom Policy**, and then upload the updated custom policy files.

+## Step 6: Test your custom policy

+Using the directory with your Azure AD B2C tenant, test your custom policy:

+1. In the Azure AD B2C tenant, and under Policies, select Identity Experience Framework.

+2. Under **Custom policies**, select the Sign in policy.

+3. For **Application**, select the web application you registered.

+4. Select **Run now**.

+5. Complete the user flow.

+ Title: Calculate cost savings in Azure Advisor

+# Calculate cost savings

+This article provides guidance on how to calculate total cost savings in Azure Advisor.

+## Export cost savings for recommendations

+> Different types of cost savings recommendations are generated using overlapping datasets (for example, VM rightsizing/shutdown, VM reservations and savings plan recommendations all consider on-demand VM usage). As a result, resource changes (e.g., VM shutdowns) or reservation/savings plan purchases will impact on-demand usage, and the resulting recommendations and associated savings forecast.

+## Understand cost savings

+Azure Advisor provides recommendations for resizing/shutting down underutilized resources, purchasing compute reserved instances, and savings plans for compute.

+These recommendations contain one or more calls-to-action and forecasted savings from following the recommendations. Recommendations should be followed in a specific order: rightsizing/shutdown, followed by reservation purchases, and finally, the savings plan purchase. This sequence allows each step to impact the subsequent ones positively.

+For example, rightsizing or shutting down resources reduces on-demand costs immediately. This change in your usage pattern essentially invalidates your existing reservation and savings plan recommendations, as they were based on your pre-rightsizing usage and costs. Updated reservation and savings plan recommendations (and their forecasted savings) should appear within three days.

+The forecasted savings from reservations and savings plans are based on actual rates and usage, while the forecasted savings from rightsizing/shutdown are based on retail rates. The actual savings may vary depending on the usage patterns and rates. Assuming there are no material changes to your usage patterns, your actual savings from reservations and savings plan should be in line with the forecasts. Savings from rightsizing/shutdown vary based on your actual rates. This is important if you intend to track cost savings forecasts from Azure Advisor.

+## April 2024

+### Azure Advisor will no longer display aggregated potential yearly savings beginning 30 September 2024

+In the Azure portal, Azure Advisor currently shows potential aggregated cost savings under the label "Potential yearly savings based on retail pricing" on pages where cost recommendations are displayed (as shown in the image). This aggregated savings estimate will be removed from the Azure portal on 30 September 2024. However, you can still evaluate potential yearly savings tailored to your specific needs by following the steps in [Calculate cost savings](/azure/advisor/advisor-how-to-calculate-total-cost-savings). All individual recommendations and their associated potential savings will remain available.

+#### Recommended action

+If you want to continue calculating aggregated potential yearly savings, follow [these steps](/azure/advisor/advisor-how-to-calculate-total-cost-savings). Note that individual recommendations might show savings that overlap with the savings shown in other recommendations, although you might not be able to benefit from them concurrently. For example, you can benefit from savings plans or from reservations for virtual machines, but not typically from both on the same virtual machines.

+Your app might need to process sentences, like "Book a ticket to Paris for me," or a fragment of a sentence, like "Booking" or "Paris flight" Users also often make spelling mistakes. When planning your app, consider whether or not you want to use [Bing Spell Check](../luis-tutorial-bing-spellcheck.md) to correct user input before passing it to LUIS.

+If you don't spell check user utterances, you should train LUIS on utterances that include typos and misspellings.

+When choosing utterances, be aware that what you think are common terms or phrases might not be common for the typical user of your client application. They might not have domain experience or use different terminology. Be careful when using terms or phrases that a user would only say if they were an expert.

+You'll find that even if you make efforts to create varied sentence patterns, you'll still repeat some vocabulary. For example, the following utterances have similar meaning, but different terminology and phrasing:

+Each intent needs to have example utterances - at least 15. If you have an intent that doesn't have any example utterances, you will not be able to train LUIS. If you have an intent with one or few example utterances, LUIS might not accurately predict the intent.

+It's better to start with a few utterances, then [review the endpoint utterances](../how-to/improve-application.md) for correct intent prediction and entity extraction.

+Set your app's version settings using the LUIS portal by selecting **Manage** from the top navigation menu, in the **Application Settings** page. You can also use the [Update Version Settings API](/rest/api/cognitiveservices-luis/authoring/versions/update?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true). See the [Reference](../luis-reference-application-settings.md) documentation for more information.

+Punctuation is a separate token in LUIS. An utterance that contains a period at the end is a separate utterance than one that doesn't contain a period at the end, and might get two different predictions.

+If punctuation isn't normalized, LUIS doesn't ignore punctuation marks by default because some client applications might place significance on these marks. Make sure to include example utterances that use punctuation, and ones that don't, for both styles to return the same relative scores.

+Training is nondeterministic: utterance prediction can vary slightly across versions or apps. You can remove nondeterministic training by updating the [version settings](/rest/api/cognitiveservices-luis/authoring/settings/update?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true) API with the UseAllTrainingData name/value pair to use all training data.

+Developers should start testing their LUIS application with real data by sending utterances to the [prediction endpoint](../luis-how-to-azure-subscription.md) URL. These utterances are used to improve the performance of the intents and entities with [Review utterances](../how-to/improve-application.md). Tests submitted using the testing pane in the LUIS portal aren't sent through the endpoint, and don't contribute to active learning.

+If the word choice or word arrangement is the same, but doesn't mean the same thing, don't label it with the entity.

+description: Use this article to see frequently asked questions about LUIS, and troubleshooting information.

+LUIS has little or no knowledge of the broader _NLP_ aspects, such as semantic similarity, without explicit identification in examples. For example, the following tokens (words) are three different things until they're used in similar contexts in the examples provided:

+For semantic similarity Natural Language Understanding (NLU), you can use [Conversation Language Understanding](../language-service/conversational-language-understanding/overview.md).

+Language Understand has separate resources, one type for authoring, and one type for querying the prediction endpoint, each has their own pricing. See [Resource usage and limits](luis-limits.md#resource-usage-and-limits).

+See [region support](https://azure.microsoft.com/global-infrastructure/services/?products=cognitive-services).

+LUIS stores data encrypted in an Azure data store corresponding to the region specified by the key. Data used to train the model such as entities, intents, and utterances will be saved in LUIS for the lifetime of the application. If an owner or contributor deletes the app, this data will be deleted with it. If an application hasn't been used in 90 days, it will be deleted. See [Data retention](luis-concept-data-storage.md) for more details about data storage.

+Enable or disable the use nondeterministic training option. When disabled, training will use all available data. When enabled (by default), training will use a random sample each time the app is trained, to be used as a negative for the intent. To make sure that you are getting same scores every time, make sure you train your LUIS app with all your data. See the [training article](how-to/train-test.md#change-deterministic-training-settings-using-the-version-settings-api) for more information.

+Designate a single main app. Any utterances that are suggested for review should be added to the main app, then moved back to all the other apps. This is either a full export of the app, or loading the labeled utterances from the main app to the other apps. Loading can be done from either the [LUIS](./luis-reference-regions.md?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true) website or the authoring API for a [single utterance](/rest/api/cognitiveservices-luis/authoring/examples/add) or for a [batch](/rest/api/cognitiveservices-luis/authoring/examples/batch?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true).

+Use this article to get started with the LUIS portal, and create an authoring resource. After completing the steps in this article, you'll be able to create and publish LUIS apps.

+1. To get started with LUIS, go to the [LUIS Portal](https://www.luis.ai/). If you don't already have a subscription, you'll be prompted to go create a [free account](https://azure.microsoft.com/free/cognitive-services/) and return back to the portal.

+4. If your subscription lives under another tenant, you won't be able to switch tenants from the existing window. You can switch tenants by closing this window and selecting the avatar containing your initials in the top-right section of the screen. Select **Choose a different authoring resource** from the top to reopen the window.

+* **Tenant Name** - the tenant your Azure subscription is associated with. You won't be able to switch tenants from the existing window. You can switch tenants by closing this window and selecting the avatar at the top-right corner of the screen, containing your initials. Select **Choose a different authoring resource** from the top to reopen the window.

+* **Azure Resource group name** - a custom resource group name you choose in your subscription. Resource groups allow you to group Azure resources for access and management. If you currently don't have a resource group in your subscription, you won't be allowed to create one in the LUIS portal. Go to [Azure portal](https://portal.azure.com/#create/Microsoft.ResourceGroup) to create one then go to LUIS to continue the sign-in process.

+* **Location** - Choose to author your applications in one of the [three authoring locations](../luis-reference-regions.md) that are currently supported by LUIS including: West US, West Europe, and East Australia

+* [Add application](/rest/api/cognitiveservices-luis/authoring/apps/add?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true) - start with an empty app and create intents, utterances, and entities.

+* [Add prebuilt application](/rest/api/cognitiveservices-luis/authoring/apps/add-custom-prebuilt-domain?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true) - start with a prebuilt domain, including intents, utterances, and entities.

+1. Send an HTTP POST [request for training](/rest/api/cognitiveservices-luis/authoring/train/train-version?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true).

+2. Request the [training status](/rest/api/cognitiveservices-luis/authoring/train/get-status?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true) with an HTTP GET request.

+Use the [Version settings API](/rest/api/cognitiveservices-luis/authoring/settings/update?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true) with the UseAllTrainingData set to *true* to turn off deterministic training.

+If you want to disable non-deterministic training for those LUIS app versions that you're building for the purpose of testing, use the [Version settings API](/rest/api/cognitiveservices-luis/authoring/versions?view=rest-cognitiveservices-luis-authoring-v3.0-preview&preserve-view=true) with the `UseAllTrainingData` setting set to `true`.

+* [Published package API](/rest/api/cognitiveservices-luis/authoring/apps/package-published-application-as-gzip?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true)

+The app running in the container can't be altered. In order to change the app in the container, you need to change the app in the LUIS service using the [LUIS](https://www.luis.ai) portal or use the LUIS [authoring APIs](/rest/api/cognitiveservices-luis/authoring/operation-groups?view=rest-cognitiveservices-luis-authoring-v3.0-preview&preserve-view=true). Then train and/or publish, then download a new package and run the container again.

+The active version is the [version](luis-how-to-manage-versions.md) of your app that is updated when you make changes to the model using the LUIS portal. In the LUIS portal, if you want to make changes to a version that isn't the active version, you need to first set that version as active.

+In LUIS, your application, or app, is a collection of machine-learned models, built on the same data set, that works together to predict intents and entities for a particular scenario. Each application has a separate prediction endpoint.

+A true negative is when your app correctly predicts no match. In batch testing, a true negative occurs when your app does predict an intent or entity for an example that hasn't been labeled with that intent or entity.

+A contributor isn't the [owner](#owner) of the app, but has the same permissions to add, edit, and delete the intents, entities, utterances. A contributor provides Azure role-based access control (Azure RBAC) to a LUIS app.

+The LUIS prediction endpoint URL is where you submit LUIS queries after the [LUIS app](#application-app) is authored and published. The endpoint URL contains the region or custom subdomain of the published app as well as the app ID. You can find the endpoint on the **[Azure resources](luis-how-to-azure-subscription.md)** page of your app, or you can get the endpoint URL from the [Get App Info](/rest/api/cognitiveservices-luis/authoring/apps/get?view=rest-cognitiveservices-luis-authoring-v3.0-preview&tabs=HTTP&preserve-view=true) API.

+[Entities](concepts/entities.md) are words in utterances that describe information used to fulfill or identify an intent. If your entity is complex and you would like your model to identify specific parts, you can break your model into subentities. For example, you might want your model to predict an address, but also the subentities of street, city, state, and zipcode. Entities can also be used as features to models. Your response from the LUIS app includes both the predicted intents and all the entities.

+The entity will be predicted if a word in the list entity is included in the list. For example, if you have a list entity called "size" and you have the words "small, medium, large" in the list, then the size entity will be predicted for all utterances where the words "small," "medium," or "large" are used regardless of the context.

+See Prebuilt model's entry for [prebuilt entity](#prebuilt-entity).

+These hints are used with the labels to learn how to predict new data. LUIS supports both phrase lists and using other models as features.

+Consider an example where you have a prebuilt-number feature that you have marked as required on the quantity entity for a menu ordering bot. When your bot sees `I want a bajillion large pizzas?`, bajillion will not be predicted as a quantity regardless of the context in which it appears. Bajillion isn't a valid number and wonΓÇÖt be predicted by the number prebuilt entity.

+An [intent](concepts/intents.md) represents a task or action the user wants to perform. It's a purpose or goal expressed in a user's input, such as booking a flight, or paying a bill. In LUIS, an utterance as a whole is classified as an intent, but parts of the utterance are extracted as entities.

+In LUIS, intents within an app are mutually exclusive. This means when you add an utterance to an intent, it is considered a _positive_ example for that intent and a _negative_ example for all other intents. Negative examples shouldn't be confused with the "None" intent, which represents utterances that are outside the scope of the app.

+Overfitting happens when the model is fixated on the specific examples and isn't able to generalize well.

+A prebuilt entity is an entity LUIS provides for common types of information such as number, URL, and email. These are created based on public data. You can choose to add a prebuilt entity as a stand-alone entity, or as a feature to an entity.

+This key isn't the authoring key. If you have a prediction endpoint key, it should be used for any endpoint requests instead of the authoring key. You can see your current prediction key inside the endpoint URL at the bottom of Azure resources page in LUIS website. It is the value of the subscription-key name/value pair.

+The [score](luis-concept-prediction-score.md) is a number from 0 and 1 that is a measure of how confident the system is that a particular input utterance matches a particular intent. A score closer to 1 means the system is very confident about its output and a score closer to 0 means the system is confident that the input doesn't match a particular output. Scores in the middle mean the system is very unsure of how to make the decision.

+|Small| the little one, 8 ounces|

+|Medium| regular, 12 ounces|

+|Large| big, 16 ounces|

+|Xtra large| the biggest one, 24 ounces|

+The model returns the normalized value for the entity when any of synonyms are seen in the input.

+The endpoint includes [timezoneOffset](luis-concept-data-alteration.md#change-time-zone-of-prebuilt-datetimev2-entity). This is the number in minutes you want to add or remove from the datetimeV2 prebuilt entity. For example, if the utterance is "what time is it now?", the datetimeV2 returned is the current time for the client request. If your client request is coming from a bot or other application that isn't the same as your bot's user, you should pass in the offset between the bot and the user.

+|`RMT33W`|1|A record locator number. It might have numbers and letters, but doesn't have any punctuation.|

+Training errors are predictions on your training data that don't match their labels.

+An [utterance](concepts/utterances.md) is user input that is short text representative of a sentence in a conversation. It's a natural language phrase such as "book 2 tickets to Seattle next Tuesday". Example utterances are added to train the model and the model predicts on new utterance at runtime.

+You can use the [v3.0-preview LUIS Programmatic APIs](/rest/api/cognitiveservices-luis/authoring/apps?view=rest-cognitiveservices-luis-authoring-v3.0-preview&preserve-view=true) to manage authoring resources.

+- Access to the Azure AI Vision Face Client SDK for mobile (IOS and Android) and web. To get started, you need to apply for the [Face Recognition Limited Access features](https://customervoice.microsoft.com/Pages/ResponsePage.aspx?id=v4j5cvGGr0GRqy180BHbR7en2Ais5pxKtso_Pz4b1_xUQjA5SkYzNDM4TkcwQzNEOE1NVEdKUUlRRCQlQCN0PWcu) to get access to the SDK. For more information, see the [Face Limited Access](/legal/cognitive-services/computer-vision/limited-access-identity?context=%2Fazure%2Fcognitive-services%2Fcomputer-vision%2Fcontext%2Fcontext) page.

+The liveness solution integration involves two different components: a frontend mobile/web application and an app server/orchestrator.

+Once you have access to the SDK, follow instruction in the [azure-ai-vision-sdk](https://github.com/Azure-Samples/azure-ai-vision-sdk) GitHub repository to integrate the UI and the code into your native mobile application. The liveness SDK supports Java/Kotlin for Android mobile applications, Swift for iOS mobile applications and JavaScript for web applications:

+- For JavaScript Web, follow the instructions in the [Web sample](https://aka.ms/liveness-sample-web)

+1. The frontend application starts the liveness check and notifies the app server.

+1. The app server creates a new liveness session with Azure AI Face Service. The service creates a liveness-session and responds back with a session-authorization-token. More information regarding each request parameter involved in creating a liveness session is referenced in [Liveness Create Session Operation](https://aka.ms/face-api-reference-createlivenesssession).

+1. The app server provides the session-authorization-token back to the frontend application.

+1. The frontend application provides the session-authorization-token during the Azure AI Vision SDKΓÇÖs initialization.

+ ```javascript

+ azureAIVisionFaceAnalyzer.token = "<INSERT_TOKEN_HERE>"

+ ```

+1. The frontend application relays the liveness check completion to the app server.

+ "fileName": "content.bin",

+ - The app server provides the reference image when creating the liveness session. More information regarding each request parameter involved in creating a liveness session with verification is referenced in [Liveness With Verify Create Session Operation](https://aka.ms/face-api-reference-createlivenesswithverifysession).

+ - The mobile application provides the reference image when initializing the SDK. This is not a supported scenario in the web solution.

+- [Liveness Session Operations](/rest/api/face/liveness-session-operations)

+* Refer to the [Read API](/rest/api/computervision/operation-groups?view=rest-computervision-v3.2-preview) for details about the methods supported by the container.

+The background removal feature is available through the [Segment](/rest/api/computervision/image-analysis/segment?view=rest-computervision-2023-02-01-preview&tabs=HTTP) API (`imageanalysis:segment`). See the [Background removal how-to guide](./how-to/background-removal.md) for more information.

+You use the [Detect] API to detect faces in an image. To get started using the REST API or a client SDK, follow a [quickstart](./quickstarts-sdk/identity-client-library.md). Or, for a more in-depth guide, see [Call the detect API](./how-to/identity-detect-faces.md).

+The face ID is a unique identifier string for each detected face in an image. Face ID requires limited access approval, which you can apply for by filling out the [intake form](https://aka.ms/facerecognition). For more information, see the Face [limited access page](/legal/cognitive-services/computer-vision/limited-access-identity?context=%2Fazure%2Fcognitive-services%2Fcomputer-vision%2Fcontext%2Fcontext). You can request a face ID in your [Detect] API call.

+Attributes are a set of features that can optionally be detected by the [Detect] API. The following attributes can be detected:

+[Detect]: /rest/api/face/face-detection-operations/detect

+You need to create a [PersonGroup](/rest/api/face/person-group-operations/create-person-group) or [LargePersonGroup](/rest/api/face/person-group-operations/create-large-person-group) to store the set of people to match against. PersonGroups hold [Person](/rest/api/face/person-group-operations/create-person-group-person) objects, which each represent an individual person and hold a set of face data belonging to that person.

+The [Train](/rest/api/face/person-group-operations/train-person-group) operation prepares the data set to be used in face data comparisons.

+The [Identify](/rest/api/face/face-recognition-operations/identify-from-large-person-group) operation takes one or several source face IDs (from a DetectedFace or PersistedFace object) and a PersonGroup or LargePersonGroup. It returns a list of the Person objects that each source face might belong to. Returned Person objects are wrapped as Candidate objects, which have a prediction confidence value.

+The [Verify](/rest/api/face/face-recognition-operations/verify-face-to-face) operation takes a single face ID (from a DetectedFace or PersistedFace object) and a Person object. It determines whether the face belongs to that same person. Verification is one-to-one matching and can be used as a final check on the results from the Identify API call. However, you can optionally pass in the PersonGroup to which the candidate Person belongs to improve the API performance.

+* [API reference](/rest/api/computervision/operation-groups?view=rest-computervision-2023-04-01-preview)

+The [Find Similar](/rest/api/face/face-recognition-operations/find-similar-from-large-face-list) operation does face matching between a target face and a set of candidate faces, finding a smaller set of faces that look similar to the target face. This is useful for doing a face search by image.

+The code snippets in this guide are written in C# by using the Azure AI Face client library. The same functionality is available through the [REST API](/rest/api/face/face-detection-operations/detect).

+The best way to compare the performances of the detection models is to use them on a sample dataset. We recommend calling the [Detect] API on a variety of images, especially images of many faces or of faces that are difficult to see, using each detection model. Pay attention to the number of faces that each model returns.

+When you use the [Detect] API, you can assign the model version with the `detectionModel` parameter. The available values are:

+A request URL for the [Detect] REST API will look like this:

+The Face service can extract face data from an image and associate it with a **Person** object through the [Add Person Group Person Face] API. In this API call, you can specify the detection model in the same way as in [Detect].

+> You don't need to use the same detection model for all faces in a **Person** object, and you don't need to use the same detection model when detecting new faces to compare with a **Person** object (in the [Identify From Person Group] API, for example).

+[Detect]: /rest/api/face/face-detection-operations/detect

+[Identify From Person Group]: /rest/api/face/face-recognition-operations/identify-from-person-group

+[Add Person Group Person Face]: /rest/api/face/person-group-operations/add-person-group-person-face

+When using the [Detect] API, assign the model version with the `recognitionModel` parameter. The available values are:

+Optionally, you can specify the _returnRecognitionModel_ parameter (default **false**) to indicate whether _recognitionModel_ should be returned in response. So, a request URL for the [Detect] REST API will look like this:

+The Face service can extract face data from an image and associate it with a **Person** object (through the [Add Person Group Person Face] API call, for example), and multiple **Person** objects can be stored together in a **PersonGroup**. Then, a new face can be compared against a **PersonGroup** (with the [Identify From Person Group] call), and the matching person within that group can be identified.

+A **PersonGroup** should have one unique recognition model for all of the **Person**s, and you can specify this using the `recognitionModel` parameter when you create the group ([Create Person Group] or [Create Large Person Group]). If you don't specify this parameter, the original `recognition_01` model is used. A group will always use the recognition model it was created with, and new faces will become associated with this model when they're added to it. This can't be changed after a group's creation. To see what model a **PersonGroup** is configured with, use the [Get Person Group] API with the _returnRecognitionModel_ parameter set as **true**.

+Correspondingly, you need to specify which model to use when detecting faces to compare against this **PersonGroup** (through the [Detect] API). The model you use should always be consistent with the **PersonGroup**'s configuration; otherwise, the operation will fail due to incompatible models.

+There is no change in the [Identify From Person Group] API; you only need to specify the model version in detection.

+You can also specify a recognition model for similarity search. You can assign the model version with `recognitionModel` when creating the **FaceList** with [Create Face List] API or [Create Large Face List]. If you don't specify this parameter, the `recognition_01` model is used by default. A **FaceList** will always use the recognition model it was created with, and new faces will become associated with this model when they're added to the list; you can't change this after creation. To see what model a **FaceList** is configured with, use the [Get Face List] API with the _returnRecognitionModel_ parameter set as **true**.

+This code creates a **FaceList** called `My face collection`, using the _recognition_04_ model for feature extraction. When you search this **FaceList** for similar faces to a new detected face, that face must have been detected ([Detect]) using the _recognition_04_ model. As in the previous section, the model needs to be consistent.

+There is no change in the [Find Similar] API; you only specify the model version in detection.

+The [Verify Face To Face] API checks whether two faces belong to the same person. There is no change in the Verify API with regard to recognition models, but you can only compare faces that were detected with the same model.

+1. Train your **PersonGroup**s using the [Train Person Group] API.

+1. Test with [Identify From Person Group] on all four **PersonGroup**s and compare the results.

+The service supports two working modes, **matchPerson** and **matchFace**. The **matchPerson** mode returns similar faces after filtering for the same person by using the [Verify API](/rest/api/face/face-recognition-operations/verify-face-to-face). The **matchFace** mode ignores the same-person filter. It returns a list of similar candidate faces that may or may not belong to the same person.

+To find four similar faces, the **matchPerson** mode returns A and B, which show the same person as the target face. The **matchFace** mode returns A, B, C, and D, which is exactly four candidates, even if some aren't the same person as the target or have low similarity.

+All of the faces in a returned group are likely to belong to the same person, but there can be several different groups for a single person. Those groups are differentiated by another factor, such as expression, for example.

+ Title: "Incident response in Azure AI Content Safety"

+description: Learn about content incidents and how you can use Azure AI Content Safety to handle them on your platform.

+#

+# Incident response

+In content moderation scenarios, incident response is the process of identifying, analyzing, containing, eradicating, and recovering from cyber incidents that involve inappropriate or harmful content on online platforms.

+An incident may involve a set of emerging content patterns (text, image, or other modalities) that violate Microsoft community guidelines or the customers' own policies and expectations. These incidents need to be mitigated quickly and accurately to avoid potential live site issues or harm to users and communities.

+## Incident response API features

+One way to deal with emerging content incidents is to use [Blocklists](/azure/ai-services/content-safety/how-to/use-blocklist), but that only allows exact text matching and no image matching. The Azure AI Content Safety incident response API offers the following advanced capabilities:

+- semantic text matching using embedding search with a lightweight classifier

+- image matching with a lightweight object-tracking model and embedding search.

+## How it works

+First, you use the API to create an incident object with a description. Then you add any number of image or text samples to the incident. No training step is needed.

+Then, you can include your defined incident in a regular text analysis or image analysis request. The service will indicate whether the submitted content is an instance of your incident. The service can still do other content moderation tasks in the same API call.

+## Limitations

+### Language availability

+The text incident response API supports all languages that are supported by Content Safety text moderation. See [Language support](/azure/ai-services/content-safety/language-support).

+### Input limitations

+See the following table for the input limitations of the incident response API:

+| Object | Limitation |

+| : | :-- |

+| Maximum length of an incident name | 100 characters |

+| Maximum number of text/image samples per incident | 1000 |

+| Maximum size of each sample | Text: 500 characters<br>Image: 4 MBΓÇ» |

+| Maximum number of text or image incidents per resource| 100 |

+| Supported Image formats | BMP, GIF, JPEG, PNG, TIF, WEBP |

+### Region availability

+To use this API, you must create your Azure AI Content Safety resource in one of the supported regions:

+- East US

+- Sweden Central

+## Next steps

+Follow the how-to guide to use the Azure AI Content Safety incident response API.

+* [Use the incident response API](../how-to/incident-response.md)

+The maximum character limit for Prompt Shields allows for a user prompt of up to 10,000 characters, while the document array is restricted to a maximum of 5 documents with a combined total not exceeding 10,000 characters.

+### Regions

+To use this API, you must create your Azure AI Content Safety resource in the supported regions. Currently, it's available in the following Azure regions:

+- East US

+- West Europe

+ Title: "Use the incident response API"

+description: Learn how to use the incident response API to mitigate harmful content incidents quickly.

+#

+# Use the incident response API

+The incident response API lets you quickly respond to emerging harmful content incidents. You can define an incident with a few examples in a specific topic, and the service will start detecting similar content.

+Follow these steps to define an incident with a few examples of text content and then analyze new text content to see if it matches the incident.

+> [!IMPORTANT]

+> This new feature is only available in the **East US** and **Sweden Central** Azure regions.

+> [!CAUTION]

+> The sample data in this guide might contain offensive content. User discretion is advised.

+## Prerequisites

+* An Azure subscription - [Create one for free](https://azure.microsoft.com/free/cognitive-services/)

+* Once you have your Azure subscription, <a href="https://aka.ms/acs-create" title="Create a Content Safety resource" target="_blank">create a Content Safety resource </a> in the Azure portal to get your key and endpoint. Enter a unique name for your resource, select your subscription, and select a resource group, supported region (East US or Sweden Central), and supported pricing tier. Then select **Create**.

+ * The resource takes a few minutes to deploy. After it finishes, Select **go to resource**. In the left pane, under **Resource Management**, select **Subscription Key and Endpoint**. The endpoint and either of the keys are used to call APIs.

+* Also [create a blob storage container](https://ms.portal.azure.com/#create/Microsoft.StorageAccount-ARM) if you want to upload your images there. You can alternatively encode your images as Base64 strings and use them directly in the API calls.

+* One of the following installed:

+ * [cURL](https://curl.haxx.se/) for REST API calls.

+ * [Python 3.x](https://www.python.org/) installed

+<!--tbd env vars-->

+## Test the text incident response API

+Use the sample code in this section to create a text incident, add samples to the incident, deploy the incident, and then detect text incidents.

+### Create an incident object

+#### [cURL](#tab/curl)

+In the commands below, replace `<your_api_key>`, `<your_endpoint>`, and other necessary parameters with your own values.

+The following command creates an incident with a name and definition.

+```bash

+ "incidentDefinition": "string"

+}'

+```

+#### [Python](#tab/python)

+First, you need to install the required Python library:

+```bash

+pip install requests

+```

+Then, define the necessary variables with your own Azure resource details:

+```python

+import requests

+API_KEY = '<your_api_key>'

+ENDPOINT = '<your_endpoint>'

+headers = {

+ 'Ocp-Apim-Subscription-Key': API_KEY,

+ 'Content-Type': 'application/json'

+}

+```

+The following command creates an incident with a name and definition.

+```python

+import requests

+import json

+url = "https://<endpoint>/contentsafety/text/incidents/<text-incident-name>?api-version=2024-02-15-preview "

+payload = json.dumps({

+ "incidentName": "<text-incident-name>",

+ "incidentDefinition": "string"

+})

+headers = {

+ 'Ocp-Apim-Subscription-Key': '<your-content-safety-key>',

+ 'Content-Type': 'application/json'

+}

+response = requests.request("PATCH", url, headers=headers, data=payload)

+print(response.text)

+```

+### Add samples to the incident

+Use the following command to add text examples to the incident.

+#### [cURL](#tab/curl)

+Currently, Azure AI Content Safety has an **F0 and S0** pricing tier. See the Azure [pricing page](https://aka.ms/content-safety-pricing) for more information.

+In the simple case without the _reasoning_ feature, the Groundedness detection API classifies the ungroundedness of the submitted content as `true` or `false`.

+ "reasoning": false

+ "reasoning": false

+To test a summarization task instead of a question answering (QnA) task, use the following sample JSON body:

+```json

+{

+ "domain": "Medical",

+ "task": "Summarization",

+ "text": "Ms Johnson has been in the hospital after experiencing a stroke.",

+ "groundingSources": ["Our patient, Ms. Johnson, presented with persistent fatigue, unexplained weight loss, and frequent night sweats. After a series of tests, she was diagnosed with HodgkinΓÇÖs lymphoma, a type of cancer that affects the lymphatic system. The diagnosis was confirmed through a lymph node biopsy revealing the presence of Reed-Sternberg cells, a characteristic of this disease. She was further staged using PET-CT scans. Her treatment plan includes chemotherapy and possibly radiation therapy, depending on her response to treatment. The medical team remains optimistic about her prognosis given the high cure rate of HodgkinΓÇÖs lymphoma."],

+ "reasoning": false

+}

+```

+| **reasoning** | (Optional) Specifies whether to use the reasoning feature. The default value is `false`. If `true`, you need to bring your own Azure OpenAI GPT-4 Turbo resources to provide an explanation. Be careful: using reasoning increases the processing time.| Boolean |

+| -**`text`** | The specific text that is ungrounded. | String |

+> [!TIP]

+> At the moment, we only support **Azure OpenAI GPT-4 Turbo** resources and do not support other GPT types. Your GPT-4 Turbo resources can be deployed in any region; however, we recommend that they be located in the same region as the content safety resources to minimize potential latency.

+In order to use your Azure OpenAI GPT4-Turbo resource to enable the reasoning feature, use Managed Identity to allow your Content Safety resource to access the Azure OpenAI resource:

+In your request to the Groundedness detection API, set the `"reasoning"` body parameter to `true`, and provide the other needed parameters:

+| **llmResource** | (Required) If you want to use your own Azure OpenAI GPT4-Turbo resource to enable reasoning, add this field and include the subfields for the resources used. | String |

+| - `resourceType `| Specifies the type of resource being used. Currently it only allows `AzureOpenAI`. We only support Azure OpenAI GPT-4 Turbo resources and do not support other GPT types. Your GPT-4 Turbo resources can be deployed in any region; however, we recommend that they be located in the same region as the content safety resources to minimize potential latency. | Enum|

+### Incident response API

+The incident response API lets you quickly define emerging harmful content patterns and scan text and images for matches. See [Incident response](./concepts/incident-response.md) to learn more.

+The **[ExportProject](/rest/api/customvision/training/projects/export?view=rest-customvision-training-v3.3&tabs=HTTP)** and **[ImportProject](/rest/api/customvision/training/projects/import?view=rest-customvision-training-v3.3&tabs=HTTP)** APIs enable this scenario by allowing you to copy projects from one Custom Vision account into others. This guide shows you how to use these REST APIs with cURL. You can also use an HTTP request service, like the [REST Client](https://marketplace.visualstudio.com/items?itemName=humao.rest-client) for Visual Studio Code, to issue the requests.

+First call **[GetProjects](/rest/api/customvision/training/projects/get?view=rest-customvision-training-v3.3&tabs=HTTP)** to see a list of your existing Custom Vision projects and their IDs. Use the training key and endpoint of your source account.

+Call **[ExportProject](/rest/api/customvision/training/projects/export?view=rest-customvision-training-v3.3&tabs=HTTP)** using the project ID and your source training key and endpoint.

+Call **[ImportProject](/rest/api/customvision/training/projects/import?view=rest-customvision-training-v3.3&tabs=HTTP)** using your target training key and endpoint, along with the reference token. You can also give your project a name in its new account.

+Within a few minutes, the target will be assigned the selected role at the selected scope. For help with these steps, see [Assign Azure roles using the Azure portal](../../role-based-access-control/role-assignments-portal.yml).

+From the **settings** tab of your project on the Custom Vision web portal, you can select a model domain for your project. You'll want to choose the domain that's closest to your use case scenario. If you're accessing Custom Vision through a client library or REST API, you'll need to specify a domain ID when creating the project. You can get a list of domain IDs with [Get Domains](/rest/api/customvision/training/domains/list?view=rest-customvision-training-v3.3&tabs=HTTP). Or, use the table below.

+For help with role assignments, see [Assign Azure roles using the Azure portal](../../role-based-access-control/role-assignments-portal.yml).

+When you call the [CreateProject](/rest/api/customvision/training/projects/create?view=rest-customvision-training-v3.3&tabs=HTTP) API, add the optional parameters _exportModelContainerUri_ and _notificationQueueUri_. Assign the URL values you got in the previous section.

+To update an existing project with Azure storage feature integration, call the [UpdateProject](/rest/api/customvision/training/projects/update?view=rest-customvision-training-v3.3&tabs=HTTP) API, using the ID of the project you want to update.

+When you're ready, call the [TrainProject](/rest/api/customvision/training/projects/train?view=rest-customvision-training-v3.3&tabs=HTTP) API on your project to do an ordinary training operation.

+When you're ready, call the [ExportIteration](/rest/api/customvision/training/iterations/export?view=rest-customvision-training-v3.3&tabs=HTTP) API to export a trained model into a specified platform.

+To enable local authentication, execute the PowerShell cmdlet **[Set-AzCognitiveServicesAccount](/powershell/module/az.cognitiveservices/set-azcognitiveservicesaccount)** with the parameter `-DisableLocalAuthΓÇ»$false`.ΓÇ» Allow a few minutes for the service to accept the change to allow local authentication requests.

+1. **Document type confidence score**: The document type confidence is an indicator of closely the analyzed document resembles documents in the training dataset. When the document type confidence is low, it's indicative of template or structural variations in the analyzed document. To improve the document type confidence, label a document with that specific variation and add it to your training dataset. Once the model is retrained, it should be better equipped to handle that class of variations.

+2. **Field level confidence**: Each labeled field extracted has an associated confidence score. This score reflects the model's confidence on the position of the value extracted. While evaluating confidence scores, you should also look at the underlying extraction confidence to generate a comprehensive confidence for the extracted result. Evaluate the `OCR` results for text extraction or selection marks depending on the field type to generate a composite confidence score for the field.

+3. **Word confidence score** Each word extracted within the document has an associated confidence score. The score represents the confidence of the transcription. The pages array contains an array of words and each word has an associated span and confidence score. Spans from the custom field extracted values match the spans of the extracted words.

+4. **Selection mark confidence score**: The pages array also contains an array of selection marks. Each selection mark has a confidence score representing the confidence of the selection mark and selection state detection. When a labeled field has a selection mark, the custom field selection combined with the selection mark confidence is an accurate representation of overall confidence accuracy.

+With the addition of table, row and cell confidence with the ```2024-02-29-preview``` API, here are some common questions that should help with interpreting the table, row, and cell scores:

+## Capabilities

+> * There are separate URLs for Document Intelligence Studio sovereign cloud regions.

+> * Azure for US Government: [Document Intelligence Studio (Azure Fairfax cloud)](https://formrecognizer.appliedai.azure.us/studio)

+> * Microsoft Azure operated by 21Vianet: [Document Intelligence Studio (Azure in China)](https://formrecognizer.appliedai.azure.cn/studio)

+* Get sample code for the language-specific `SDKs` to integrate into your applications.

+Use the [Document Intelligence Studio quickstart](quickstarts/try-document-intelligence-studio.md) to get started analyzing documents with document analysis or prebuilt models. Build custom models and reference the models in your applications using one of the [language specific `SDKs`](quickstarts/get-started-sdks-rest-api.md?view=doc-intel-3.0.0&preserve-view=true) and other quickstarts.

+If you're visiting the Studio for the first time, follow the [getting started guide](studio-overview.md#get-started) to set up the Studio for use.

+* Use the custom extraction model labeling page to navigate through your training documents with ease by making use of the search, filter, and sort by feature.

+* **Custom extraction models**: Document Intelligence's custom models enable you to extract fields and values from models trained with your data, tailored to your forms and documents. To extract data from multiple form types, create standalone custom models or combine two, or more, custom models and create a composed model. Start with the [Studio Custom models feature](https://documentintelligence.ai.azure.com/studio/custommodel/projects). Use the help wizard, labeling interface, training step, and visualizations to understand how the feature works. Test the custom model with your sample documents and iterate to improve the model. To learn more, *see* the [Custom models overview](concept-custom.md) to learn more.

+* **Custom classification models**: Document classification is a new scenario supported by Document Intelligence. the document classifier API supports classification and splitting scenarios. Train a classification model to identify the different types of documents your application supports. The input file for the classification model can contain multiple documents and classifies each document within an associated page range. To learn more, *see* [custom classification models](concept-custom-classifier.md).

+* **Add-on Capabilities**: Document Intelligence now supports more sophisticated analysis capabilities. These optional capabilities can be enabled and disabled in the studio using the `Analze Options` button in each model page. There are four add-on capabilities available: highResolution, formula, font, and barcode extraction capabilities. To learn more, *see* [Add-on capabilities](concept-add-on-capabilities.md).

+Before requesting a quota increase (where applicable), ensure that it's necessary. Document Intelligence service uses autoscaling to bring the required computational resources `on-demand`, keep the customer costs low, and deprovision unused resources by not maintaining an excessive amount of hardware capacity.

+* Get sample code for the language specific `SDKs` to integrate into your applications.

+## Get started

+## Authorization policies

+Your organization can opt to disable local authentication and enforce Microsoft Entra (formerly Azure Active Directory) authentication for Azure AI Document Intelligence resources and Azure blob storage.

+* Using Microsoft Entra authentication requires that key based authorization is disabled. After key access is disabled, Microsoft Entra ID is the only available authorization method.

+* Microsoft Entra allows granting minimum privileges and granular control for Azure resources.

+* For more information *see* the following guidance:

+ * [Disable local authentication for Azure AI Services](../disable-local-auth.md).

+ * [Prevent Shared Key authorization for an Azure Storage account](../../storage/common/shared-key-authorization-prevent.md)

+* **Designating role assignments**. Document Intelligence Studio basic access requires the [`Cognitive Services User`](../../role-based-access-control/built-in-roles/ai-machine-learning.md#cognitive-services-user) role. For more information, *see* [Document Intelligence role assignments](quickstarts/try-document-intelligence-studio.md#azure-role-assignments) and [Document Intelligence Studio Permission](faq.yml#what-permissions-do-i-need-to-access-document-intelligence-studio-).

+## Authentication

+Navigate to the [Document Intelligence Studio](https://formrecognizer.appliedai.azure.com/). If it's your first time logging in, a popup window appears prompting you to configure your service resource. In accordance with your organization's policy, you have one or two options:

+* **Microsoft Entra authentication: access by Resource (recommended)**.

+ * Choose your existing subscription.

+ * Select an existing resource group within your subscription or create a new one.

+ * Select your existing Document Intelligence or Azure AI services resource.

+ :::image type="content" source="media/studio/configure-service-resource.png" alt-text="Screenshot of configure service resource form from the Document Intelligence Studio.":::

+* **Local authentication: access by API endpoint and key**.

+ * Retrieve your endpoint and key from the Azure portal.

+ * Go to the overview page for your resource and select **Keys and Endpoint** from the left navigation bar.

+ * Enter the values in the appropriate fields.

+ :::image type="content" source="media/studio/keys-and-endpoint.png" alt-text="Screenshot of the keys and endpoint page in the Azure portal.":::

+## Try a Document Intelligence model

+1. Once your resource is configured, you can try the different models offered by Document Intelligence Studio. From the front page, select any Document Intelligence model to try using with a no-code approach.

+1. To test any of the document analysis or prebuilt models, select the model and use one of the sample documents or upload your own document to analyze. The analysis result is displayed at the right in the content-result-code window.

+1. Custom models need to be trained on your documents. See [custom models overview](concept-custom.md) for an overview of custom models.

+1. After validating the scenario in the Document Intelligence Studio, use the [**C#**](quickstarts/get-started-sdks-rest-api.md?view=doc-intel-3.0.0&preserve-view=true), [**Java**](quickstarts/get-started-sdks-rest-api.md?view=doc-intel-3.0.0&preserve-view=true), [**JavaScript**](quickstarts/get-started-sdks-rest-api.md?view=doc-intel-3.0.0&preserve-view=true), or [**Python**](quickstarts/get-started-sdks-rest-api.md?view=doc-intel-3.0.0&preserve-view=true) client libraries or the [**REST API**](quickstarts/get-started-sdks-rest-api.md?view=doc-intel-3.0.0&preserve-view=true) to get started incorporating Document Intelligence models into your own applications.

+To learn more about each model, *see* our concept pages.

A Logic App is the Azure resource you create when you want to develop a workflow. Here are a few examples of what you can do with a Logic App:

+Let's quickly review what we completed before we test our flow:

+Now that we created the flow, the last thing to do is to test it and make sure that we're getting the expected behavior.

+Congratulations! You completed this tutorial.

+## May 2024

+The Document Intelligence Studio has added support for Microsoft Entra (formerly Azure Active Directory) authentication. For more information, *see* [Document Intelligence Studio overview](studio-overview.md#authentication).

+## Data privacy for Immersive reader

+Immersive reader doesn't store any customer data.

+As you use this API in your application, see the [reference documentation](/rest/api/language) for additional information.

+Within a few minutes, the target will be assigned the selected role at the selected scope. For help with these steps, see [Assign Azure roles using the Azure portal](../../../role-based-access-control/role-assignments-portal.yml).

+ *[Language Runtime CLU APIs](/rest/api/language)

+When you send asynchronous requests, you'll incur charges based on number of text records you include in your request, for each feature use. For example, if you send a text record for sentiment analysis and NER, it will be counted as sending two text records, and you'll be charged for both according to your [pricing tier](https://azure.microsoft.com/pricing/details/cognitive-services/language-service/).

+To submit an asynchronous job, review the [reference documentation](/rest/api/language/analyze-text-submit-job) for the JSON body you'll send in your request.

+A successful call will return a 202 response code. The `operation-location` in the response header will be the URL you'll use to retrieve the API results. The value will look similar to the following URL:

+To [get the status and retrieve the results](/rest/api/language/analyze-text-job-status) of the request, send a GET request to the URL you received in the `operation-location` header from the previous API response. Remember to include your key in the `Ocp-Apim-Subscription-Key`. The response will include the results of your API call.

+Starting in version `2022-07-01-preview` of the REST API, you can request automatic [language detection](../language-detection/overview.md) on your documents. By setting the `language` parameter to `auto`, the detected language code of the text will be returned as a language value in the response. This language detection won't incur extra charges to your Language resource.

+## Addressing out of domain utterances

+Customers can use the new recipe version '2024-06-01-preview' in case the model has poor AIQ on out of domain utterances. An example of this with the default recipe can be like the below where the model has 3 intents Sports, QueryWeather and Alarm. The test utterances are out of domain utterances and the model classifies them as InDomain with a relatively high confidence score.

+| Text | Predicted intent | Confidence score |

+|-|-|-|

+| "*Who built the Eiffel Tower?*" | `Sports` | 0.90 |

+| "*Do I look good to you today?*" | `QueryWeather` | 1.00 |

+| "*I hope you have a good evening.*" | `Alarm` | 0.80 |

+To address this, use the `2024-06-01-preview` configuration version that is built specifically to address this issue while also maintaining reasonably good quality on In Domain utterances.

+```console

+curl --location 'https://<your-resource>.cognitiveservices.azure.com/language/authoring/analyze-conversations/projects/<your-project>/:train?api-version=2022-10-01-preview' \

+--header 'Ocp-Apim-Subscription-Key: <your subscription key>' \

+--header 'Content-Type: application/json' \

+--data '{

+ΓÇéΓÇéΓÇéΓÇéΓÇéΓÇé"modelLabel": "<modelLabel>",

+ΓÇéΓÇéΓÇéΓÇéΓÇéΓÇé"trainingMode": "advanced",

+ΓÇéΓÇéΓÇéΓÇéΓÇéΓÇé"trainingConfigVersion": "2024-06-01-preview",

+ΓÇéΓÇéΓÇéΓÇéΓÇéΓÇé"evaluationOptions": {

+ΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇé"kind": "percentage",

+ΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇé"testingSplitPercentage": 0,

+ΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇéΓÇé"trainingSplitPercentage": 100

+ΓÇéΓÇéΓÇéΓÇéΓÇéΓÇé}

+}

+```

+Once the request is sent, you can track the progress of the training job in Language Studio as usual.

+Caveats:

+- The None Score threshold for the app (confidence threshold below which the topIntent is marked as None) when using this recipe should be set to 0. This is because this new recipe attributes a certain portion of the in domain probabiliities to out of domain so that the model is not incorrectly overconfident about in domain utterances. As a result, users may see slightly reduced confidence scores for in domain utterances as compared to the prod recipe.

+- This recipe is not recommended for apps with just two (2) intents, such as IntentA and None, for example.

+- This recipe is not recommended for apps with low number of utterances per intent. A minimum of 25 utterances per intent is highly recommended.

+Use this article to get an overview of the new API changes starting from `2023-04-15-preview` version. This API change mainly introduces two new concepts (`entity types` and `entity tags`) replacing the `category` and `subcategory` fields in the current Generally Available API. A detailed overview of each API parameter and the supported API versions it corresponds to can be found on the [Skill Parameters][../how-to/skill-parameters.md] page

+The changes introduce better flexibility for the named entity recognition service, including:

+Updates to the structure of input formats:

+ΓÇó InclusionList

+ΓÇó ExclusionList

+ΓÇó Overlap policy

+Updates to the handling of output formats:

+* More granular entity recognition outputs through introducing the tags list where an entity could be tagged by more than one entity tag.

+# Learn about named entity recognition skill parameters

+Use this article to get an overview of the different API parameters used to adjust the input to a NER API call.

+## InclusionList parameter

+The ΓÇ£inclusionListΓÇ¥ parameter allows for you to specify which of the NER entity tags, listed here [link to Preview API table], you would like included in the entity list output in your inference JSON listing out all words and categorizations recognized by the NER service. By default, all recognized entities will be listed.

+## ExclusionList parameter

+The ΓÇ£exclusionListΓÇ¥ parameter allows for you to specify which of the NER entity tags, listed here [link to Preview API table], you would like excluded in the entity list output in your inference JSON listing out all words and categorizations recognized by the NER service. By default, all recognized entities will be listed.

+## Example

+To do: work with Bidisha & Mikael to update with a good example

+## overlapPolicy parameter

+The ΓÇ£overlapPolicyΓÇ¥ parameter allows for you to specify how you like the NER service to respond to recognized words/phrases that fall into more than one category.

+By default, the overlapPolicy parameter will be set to ΓÇ£matchLongestΓÇ¥. This option will categorize the extracted word/phrase under the entity category that can encompass the longest span of the extracted word/phrase (longest defined by the most number of characters included).

+The alternative option for this parameter is ΓÇ£allowOverlapΓÇ¥, where all possible entity categories will be listed.

+Parameters by supported API version

+Named Entity Recognition (NER) is one of the features offered by [Azure AI Language](../overview.md), a collection of machine learning and AI algorithms in the cloud for developing intelligent applications that involve written language. The NER feature can identify and categorize entities in unstructured text. For example: people, places, organizations, and quantities. The prebuilt NER feature has a pre-set list of [recognized entities](concepts/named-entity-categories.md). The custom NER feature allows you to train the model to recognize specialized entities specific to your use case.

+> [!NOTE]

+> [Entity Resolution](concepts/entity-resolutions.md) was upgraded to the [Entity Metadata](concepts/entity-metadata.md) starting in API version 2023-04-15-preview. If you are calling the preview version of the API equal or newer than 2023-04-15-preview, please check out the [Entity Metadata](concepts/entity-metadata.md) article to use the resolution feature.

+Use this article to learn which natural languages are supported by the PII and conversation PII features of Azure AI Language.

+As of June 2024, we now provide General Availability support for the Conversational PII service (English-language only).

+Customers can now redact transcripts, chats, and other text written in a conversational style (i.e. text with ΓÇ£umΓÇ¥s, ΓÇ£ahΓÇ¥s, multiple speakers, and the spelling out of words for more clarity) with better confidence in AI quality, Azure SLA support and production environment support, and enterprise-grade security in mind.

+PII detection is one of the features offered by [Azure AI Language](../overview.md), a collection of machine learning and AI algorithms in the cloud for developing intelligent applications that involve written language. The PII detection feature can **identify, categorize, and redact** sensitive information in unstructured text. For example: phone numbers, email addresses, and forms of identification. Azure AI Language supports general text PII redaction, as well as [Conversational PII](how-to-call-for-conversations.md), a specialized model for handling speech transcriptions and the more informal, conversational tone of meeting and call transcripts. The service also supports [Native Document PII redaction](#native-document-support), where the input and output are structured document files.

+In the abstractive text summarization scenario, each document (whether it has a provided label or not) is expected to be provided in a plain .txt file. The file contains one or more lines. If multiple lines are provided, each is assumed to be a paragraph of the document. The following is an example document with three paragraphs.

+In both text and conversation summarization scenarios, a set of documents and corresponding labels can be provided in a single JSON file that references individual document/conversation and summary files.

+The following is an example mapping file for the abstractive text summarization scenario with three documents and corresponding labels.

+ - build-2024

+There's another feature in Azure AI Language named [text summarization](../overview.md?tabs=text-summarization) that is more suitable to summarize documents into concise summaries. When you're deciding between text summarization and conversation summarization, consider the following points:

+* Input format: Conversation summarization can operate on both chat text and speech transcripts, which have speakers and their utterances. Text summarization operates using simple text, or Word, PDF, or PowerPoint formats.

+ - build-2024

+# How to use text summarization

+Text summarization is designed to shorten content that users consider too long to read. Both extractive and abstractive summarization condense articles, papers, or documents to key sentences.

+|Extractive |[Extractive Summarization](#try-text-extractive-summarization) |

+|Abstractive |[Abstractive Summarization](#try-text-abstractive-summarization)|

+### Getting text summarization results

+The text summarization API request is processed upon receipt of the request by creating a job for the API backend. If the job succeeded, the output of the API is returned. The output is available for retrieval for 24 hours. After this time, the output is purged. Due to multilingual and emoji support, the response might contain text offsets. See [how to process offsets](../../concepts/multilingual-emoji-support.md) for more information.

+### Try text extractive summarization

+You can use text extractive summarization to get summaries of articles, papers, or documents. To see an example, see the [quickstart article](../quickstart.md).

+### Try text abstractive summarization

+The following example gets you started with text abstractive summarization:

+curl -i -X POST https://<your-language-resource-endpoint>/language/analyze-text/jobs?api-version=2023-04-01 \

+ "displayName": "Text Abstractive Summarization Task Example",

+ "taskName": "Text Abstractive Summarization Task 1",

+### Abstractive text summarization example JSON response

+ "displayName": "Text Abstractive Summarization Task Example",

+ "taskName": "Text Abstractive Summarization Task 1",

+The query-based text summarization API is an extension to the existing text summarization API.

+ "displayName": "Text Extractive Summarization Task Example",

+"tasks": [

+ "kind": "AbstractiveSummarization",

+ "summaryLength": "short"

+ }

+ }, {

+ "taskName": "Query_based Extractive Summarization",

+ "query": "XYZ-code",

+ "sentenceCount": 3

+* oneSentence: Generates a summary of mostly 1 sentence, with around 80 tokens.

+## Text and document summarization

+Extractive and abstractive text summarization as well as document summarization support the following languages:

+| Arabic | `ar` | |

+ Title: What is summarization?

+# What is summarization?

+Though the services are labeled document and conversation summarization, text summarization only accepts plain text blocks, and conversation summarization accept various speech artifacts in order for the model to learn more. If you want to process a conversation but only care about text, you can use text summarization for that scenario.

+# [Text summarization](#tab/text-summarization)

+* **[Quickstarts](quickstart.md?pivots=rest-api&tabs=text-summarization)** are getting-started instructions to guide you through making requests to the service.

+Text summarization uses natural language processing techniques to generate a summary for documents. There are two supported API approaches to automatic summarization: extractive and abstractive.

+## Key features for text summarization

+There are two aspects of text summarization this API provides:

+* [**Extractive summarization**](how-to/document-summarization.md#try-text-extractive-summarization): Produces a summary by extracting salient sentences within the document.

+ * Rank score: The rank score indicates how relevant a sentence is to a document's main topic. Text summarization ranks extracted sentences, and you can determine whether they're returned in the order they appear, or according to their rank.

+* [**Abstractive summarization**](how-to/document-summarization.md#try-text-abstractive-summarization): Generates a summary that doesn't use the same words as in the document, but captures the main idea.

+The text summarization API request is processed upon receipt of the request by creating a job for the API backend. If the job succeeded, the output of the API is returned. The output is available for retrieval for 24 hours. After this time, the output is purged. Due to multilingual and emoji support, the response can contain text offsets. For more information, see [how to process offsets](../concepts/multilingual-emoji-support.md).

+# [Document summarization](#tab/document-summarization)

+This documentation contains the following article types:

+* **[Quickstarts](quickstart.md?pivots=rest-api&tabs=text-summarization)** are getting-started instructions to guide you through making requests to the service.

+* **[How-to guides](how-to/document-summarization.md)** contain instructions for using the service in more specific or customized ways.

+Document summarization uses natural language processing techniques to generate a summary for documents. There are two supported API approaches to automatic summarization: extractive and abstractive.

+# [Text summarization](#tab/text-summarization)

+A native document refers to the file format used to create the original document such as Microsoft Word (docx) or a portable document file (pdf). Native document support eliminates the need for text preprocessing prior to using Azure AI Language resource capabilities. Currently, native document support is available for both [**AbstractiveSummarization**](../summarization/how-to/document-summarization.md#try-text-abstractive-summarization) and [**ExtractiveSummarization**](../summarization/how-to/document-summarization.md#try-text-extractive-summarization) capabilities.

+ Currently **Text Summarization** supports the following native document formats:

+|File type|File extension|Description|

+||--|--|

+|Text| `.txt`|An unformatted text document.|

+|Adobe PDF| `.pdf` |A portable document file formatted document.|

+|Microsoft Word|`.docx`|A Microsoft Word document file.|

+For more information, *see* [**Use native documents for language processing**](../native-document-support/use-native-documents.md)

+## Key features for conversation summarization

+| `tool_choice` | string or object | Controls which (if any) tool is called by the model. `none` means the model won't call any tools and instead generates a message. `auto` is the default value and means the model can pick between generating a message or calling a tool. Specifying a particular tool like `{"type": "file_search"}` or `{"type": "function", "function": {"name": "my_function"}}` forces the model to call that tool. |

+| `max_prompt_tokens` | integer or null | The maximum number of prompt tokens specified to have been used over the course of the run. |

+| `max_completion_tokens` | integer or null | The maximum number of completion tokens specified to have been used over the course of the run. |

+| `cancelled_at`| integer or null | The Unix timestamp (in seconds) for when the run step was canceled.|

+## Stream a run result (preview)

+Stream the result of executing a Run or resuming a Run after submitting tool outputs. You can stream events after:

+* [Create Thread and Run](#create-thread-and-run)

+* [Create Run](#create-run)

+* [Submit Tool Outputs](#submit-tool-outputs-to-run)

+To stream a result, pass `"stream": true` while creating a run. The response will be a [Server-Sent events](https://html.spec.whatwg.org/multipage/server-sent-events.html#server-sent-events) stream.

+### Streaming example

+```python

+from typing_extensions import override

+from openai import AssistantEventHandler

+

+# First, we create a EventHandler class to define

+# how we want to handle the events in the response stream.

+

+class EventHandler(AssistantEventHandler):

+ @override

+ def on_text_created(self, text) -> None:

+ print(f"\nassistant > ", end="", flush=True)

+

+ @override

+ def on_text_delta(self, delta, snapshot):

+ print(delta.value, end="", flush=True)

+

+ def on_tool_call_created(self, tool_call):

+ print(f"\nassistant > {tool_call.type}\n", flush=True)

+

+ def on_tool_call_delta(self, delta, snapshot):

+ if delta.type == 'code_interpreter':

+ if delta.code_interpreter.input:

+ print(delta.code_interpreter.input, end="", flush=True)

+ if delta.code_interpreter.outputs:

+ print(f"\n\noutput >", flush=True)

+ for output in delta.code_interpreter.outputs:

+ if output.type == "logs":

+ print(f"\n{output.logs}", flush=True)

+

+# Then, we use the `create_and_stream` SDK helper

+# with the `EventHandler` class to create the Run

+# and stream the response.

+

+with client.beta.threads.runs.stream(

+ thread_id=thread.id,

+ assistant_id=assistant.id,

+ instructions="Please address the user as Jane Doe. The user has a premium account.",

+ event_handler=EventHandler(),

+) as stream:

+ stream.until_done()

+```

+## Message delta object

+Represents a message delta. For example any changed fields on a message during streaming.

+|Name | Type | Description |

+| | | |

+| `id` | string | The identifier of the message, which can be referenced in API endpoints. |

+| `object` | string | The object type, which is always `thread.message.delta`. |

+| `delta` | object | The delta containing the fields that have changed on the Message. |

+## Run step delta object

+Represents a run step delta. For example any changed fields on a run step during streaming.

+|Name | Type | Description |

+| | | |

+| `id` | string | The identifier of the run step, which can be referenced in API endpoints. |

+| `object` | string | The object type, which is always `thread.run.step.delta`. |

+| `delta` | object | The delta containing the fields that have changed on the run step.

+## Assistant stream events

+Represents an event emitted when streaming a Run. Each event in a server-sent events stream has an event and data property:

+```json

+event: thread.created

+data: {"id": "thread_123", "object": "thread", ...}

+```

+Events are emitted whenever a new object is created, transitions to a new state, or is being streamed in parts (deltas). For example, `thread.run.created` is emitted when a new run is created, `thread.run.completed` when a run completes, and so on. When an Assistant chooses to create a message during a run, we emit a `thread.message.created` event, a `thread.message.in_progress` event, many thread.`message.delta` events, and finally a `thread.message.completed` event.

+|Name | Type | Description |

+| model| string | Required | Model deployment name of the model to use.|

+| temperature | number or null | Optional | Defaults to 1. Determines what sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. |

+| top_p | number or null | Optional | Defaults to 1. An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both. |

+| response_format | string or object | Optional | Specifies the format that the model must output. Compatible with GPT-4 Turbo and all GPT-3.5 Turbo models since gpt-3.5-turbo-1106. Setting this parameter to `{ "type": "json_object" }` enables JSON mode, which guarantees the message the model generates is valid JSON. Importantly, when using JSON mode, you must also instruct the model to produce JSON yourself using a system or user message. Without this instruction, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Additionally, the message content may be partially cut off if you use `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length. |

+Assistants use the [same API for file upload as fine-tuning](/rest/api/azureopenai/files/upload?view=rest-azureopenai-2024-05-01-preview&tabs=HTTP&preserve-view=true). When uploading a file you have to specify an appropriate value for the [purpose parameter](/rest/api/azureopenai/files/upload?view=rest-azureopenai-2024-05-01-preview&tabs=HTTP#purpose&preserve-view=true).

+ Title: Azure OpenAI Service Assistants API concepts

+* Assistants can call Azure OpenAIΓÇÖs [models](../concepts/models.md) with specific instructions to tune their personality and capabilities.

+* Assistants can access **multiple tools in parallel**. These can be both Azure OpenAI-hosted tools like [code interpreter](../how-to/code-interpreter.md) and [file search](../how-to/file-search.md), or tools you build, host, and access through [function calling](../how-to/function-calling.md).

+* Assistants can access **persistent Threads**. Threads simplify AI application development by storing message history and truncating it when the conversation gets too long for the model's context length. You create a Thread once, and simply append Messages to it as your users reply.

+* Assistants can access files in several formats. Either as part of their creation or as part of Threads between Assistants and users. When using tools, Assistants can also create files (such as images or spreadsheets) and cite files they reference in the Messages they create.

+> [!TIP]

+> There is no additional [pricing](https://azure.microsoft.com/pricing/details/cognitive-services/openai-service/) or [quota](../quotas-limits.md) for using Assistants unless you use the [code interpreter](../how-to/code-interpreter.md) or [file search](../how-to/file-search.md) tools.

+Assistants API is built on the same capabilities that power OpenAIΓÇÖs GPT product. Some possible use cases range from AI-powered product recommender, sales analyst app, coding assistant, employee Q&A chatbot, and more. Start building on the no-code Assistants playground on the Azure OpenAI Studio, AI Studio, or start building with the API.

+> Retrieving untrusted data using Function calling, Code Interpreter or File Search with file input, and Assistant Threads functionalities could compromise the security of your Assistant, or the application that uses the Assistant. Learn about mitigation approaches [here](https://aka.ms/oai/assistant-rai).

+## Parameters

+The Assistants API has support for several parameters that let you customize the Assistants' output. The `tool_choice` parameter lets you force the Assistant to use a specified tool. You can also create messages with the `assistant` role to create custom conversation histories in Threads. `temperature`, `top_p`, `response_format` let you further tune responses. For more information, see the [reference](../assistants-reference.md#create-an-assistant) documentation.

+## Context window management

+Assistants automatically truncates text to ensure it stays within the model's maximum context length. You can customize this behavior by specifying the maximum tokens you'd like a run to utilize and/or the maximum number of recent messages you'd like to include in a run.

+### Max completion and max prompt tokens

+To control the token usage in a single Run, set `max_prompt_tokens` and `max_completion_tokens` when you create the Run. These limits apply to the total number of tokens used in all completions throughout the Run's lifecycle.

+For example, initiating a Run with `max_prompt_tokens` set to 500 and `max_completion_tokens` set to 1000 means the first completion will truncate the thread to 500 tokens and cap the output at 1000 tokens. If only 200 prompt tokens and 300 completion tokens are used in the first completion, the second completion will have available limits of 300 prompt tokens and 700 completion tokens.

+If a completion reaches the `max_completion_tokens` limit, the Run will terminate with a status of incomplete, and details will be provided in the `incomplete_details` field of the Run object.

+When using the File Search tool, we recommend setting the `max_prompt_tokens` to no less than 20,000. For longer conversations or multiple interactions with File Search, consider increasing this limit to 50,000, or ideally, removing the `max_prompt_tokens` limits altogether to get the highest quality results.

+## Truncation strategy

+You may also specify a truncation strategy to control how your thread should be rendered into the model's context window. Using a truncation strategy of type `auto` will use OpenAI's default truncation strategy. Using a truncation strategy of type `last_messages` will allow you to specify the number of the most recent messages to include in the context window.

+Azure OpenAI Service includes a content filtering system that works alongside core models, including DALL-E image generation models. This system works by running both the prompt and completion through an ensemble of classification models aimed at detecting and preventing the output of harmful content. The content filtering system detects and takes action on specific categories of potentially harmful content in both input prompts and output completions. Variations in API configurations and application design might affect completions and thus filtering behavior.

+## Risk categories

+## Prompt Shields

+|Type| Description|

+|--|--|

+|Prompt Shield for Jailbreak Attacks |Jailbreak Attacks are User Prompts designed to provoke the Generative AI model into exhibiting behaviors it was trained to avoid or to break the rules set in the System Message. Such attacks can vary from intricate roleplay to subtle subversion of the safety objective. |

+|Prompt Shield for Indirect Attacks |Indirect Attacks, also referred to as Indirect Prompt Attacks or Cross-Domain Prompt Injection Attacks, are a potential vulnerability where third parties place malicious instructions inside of documents that the Generative AI system can access and process. Requires [document embedding and formatting](#embedding-documents-in-your-prompt). |

+The default content filtering configuration for the GPT model series is set to filter at the medium severity threshold for all four content harm categories (hate, violence, sexual, and self-harm) and applies to both prompts (text, multi-modal text/image) and completions (text). This means that content that is detected at severity level medium or high is filtered, while content detected at severity level low isn't filtered by the content filters. For DALL-E, the default severity threshold is set to low for both prompts (text) and completions (images), so content detected at severity levels low, medium, or high is filtered. The configurability feature is available in preview and allows customers to adjust the settings, separately for prompts and completions, to filter content for each content category at different severity levels as described in the table below:

+| Low, medium, high | Yes | Yes | Strictest filtering configuration. Content detected at severity levels low, medium and high is filtered.|

+| Medium, high | Yes | Yes | Content detected at severity level low isn't filtered, content at medium and high is filtered.|

+| High | Yes| Yes | Content detected at severity levels low and medium isn't filtered. Only content at severity level high is filtered. Requires approval¹.|

+| No filters | If approved¹| If approved¹| No content is filtered regardless of severity level detected. Requires approval¹.|

+¹ For Azure OpenAI models, only customers who have been approved for modified content filtering have full content filtering control and can turn content filters off. Apply for modified content filters via this form: [Azure OpenAI Limited Access Review: Modified Content Filters and Abuse Monitoring (microsoft.com)](https://customervoice.microsoft.com/Pages/ResponsePage.aspx?id=v4j5cvGGr0GRqy180BHbR7en2Ais5pxKtso_Pz4b1_xURE01NDY1OUhBRzQ3MkQxMUhZSE1ZUlJKTiQlQCN0PWcu)

+## Document embedding in prompts

+A key aspect of Azure OpenAI's Responsible AI measures is the content safety system. This system runs alongside the core GPT model to monitor any irregularities in the model input and output. Its performance is improved when it can differentiate between various elements of your prompt like system input, user input, and AI assistant's output.

+

+For enhanced detection capabilities, prompts should be formatted according to the following recommended methods.

+### Chat Completions API

+The Chat Completion API is structured by definition. It consists of a list of messages, each with an assigned role.

+The safety system will parse this structured format and apply the following behavior:

+- On the latest ΓÇ£userΓÇ¥ content, the following categories of RAI Risks will be detected:

+ - Hate

+ - Sexual

+ - Violence

+ - Self-Harm

+ - Jailbreak (optional)

+This is an example message array:

+```json

+{"role": "system", "content": "Provide some context and/or instructions to the model."},

+{"role": "user", "content": "Example question goes here."},

+{"role": "assistant", "content": "Example answer goes here."},

+{"role": "user", "content": "First question/message for the model to actually respond to."}

+```

+### Embedding documents in your prompt

+In addition to detection on last user content, Azure OpenAI also supports the detection of specific risks inside context documents via Prompt Shields ΓÇô Indirect Prompt Attack Detection. You should identify parts of the input that are a document (e.g. retrieved website, email, etc.) with the following document delimiter.

+```

+<documents>

+*insert your document content here*

+</documents>

+```

+When you do so, the following options are available for detection on tagged documents:

+- On each tagged ΓÇ£documentΓÇ¥ content, detect the following categories:

+ - Indirect attacks (optional)

+Here is an example chat completion messages array:

+```json

+{"role": "system", "content": "Provide some context and/or instructions to the model, including document context. \"\"\" <documents>\n*insert your document content here*\n<\\documents> \"\"\""},

+{"role": "user", "content": "First question/message for the model to actually respond to."}

+```

+#### JSON escaping

+When you tag unvetted documents for detection, the document content should be JSON-escaped to ensure successful parsing by the Azure OpenAI safety system.

+For example, see the following email body:

+```

+Hello Josè,

+I hope this email finds you well today.

+```

+With JSON escaping, it would read:

+```

+Hello Jos\u00E9,\nI hope this email finds you well today.

+```

+The escaped text in a chat completion context would read:

+```json

+{"role": "system", "content": "Provide some context and/or instructions to the model, including document context. \"\"\" <documents>\n Hello Jos\\u00E9,\\nI hope this email finds you well today. \n<\\documents> \"\"\""},

+{"role": "user", "content": "First question/message for the model to actually respond to."}

+```

+This section describes the Azure OpenAI content streaming experience and options. Customers have the option to receive content from the API as it's generated, instead of waiting for chunks of content that have been verified to pass your content filters.

+### Asynchronous Filter

+Customers can choose the Asynchronous Filter as an additional option, providing a new streaming experience. In this case, content filters are run asynchronously, and completion content is returned immediately with a smooth token-by-token streaming experience. No content is buffered, which allows for a fast streaming experience with zero latency associated with content safety.

+**Customer Copyright Commitment**: Content that is retroactively flagged as protected material may not be eligible for Customer Copyright Commitment coverage.

+To enable Asynchronous Filter in Azure OpenAI Studio, follow the [Content filter how-to guide](/azure/ai-services/openai/how-to/content-filters) to create a new content filtering configuration, and select **Asynchronous Filter** in the Streaming section.

+Below is a real chat completion response using Asynchronous Filter. Note how the prompt annotations aren't changed, completion tokens are sent without annotations, and new annotation messages are sent without tokens&mdash;they are instead associated with certain content filter offsets.

+> When content filtering is triggered for a prompt and a `"status": 400` is received as part of the response there will be a charge for this request as the prompt was evaluated by the service. [Charges will also occur](https://azure.microsoft.com/pricing/details/cognitive-services/openai-service/) when a `"status":200` is received with `"finish_reason": "content_filter"`. In this case the prompt did not have any issues, but the completion generated by the model was detected to violate the content filtering rules which results in the completion being filtered.

+recommendations: false

+# Getting started with customizing a large language model (LLM)

+There are several techniques for adapting a pre-trained language model to suit a specific task or domain. These include prompt engineering, RAG (Retrieval Augmented Generation), and fine-tuning. These three techniques are not mutually exclusive but are complementary methods that in combination can be applicable to a specific use case. In this article, we'll explore these techniques, illustrative use cases, things to consider, and provide links to resources to learn more and get started with each.

+## Prompt engineering

+### Definition

+[Prompt engineering](./prompt-engineering.md) is a technique that is both art and science, which involves designing prompts for generative AI models. This process utilizes in-context learning ([zero shot and few shot](./prompt-engineering.md#examples)) and, with iteration, improves accuracy and relevancy in responses, optimizing the performance of the model.

+### Illustrative use cases

+A Marketing Manager at an environmentally conscious company can use prompt engineering to help guide the model to generate descriptions that are more aligned with their brandΓÇÖs tone and style. For instance, they can add a prompt like "Write a product description for a new line of eco-friendly cleaning products that emphasizes quality, effectiveness, and highlights the use of environmentally friendly ingredients" to the input. This will help the model generate descriptions that are aligned with their brandΓÇÖs values and messaging.

+### Things to consider

+- **Prompt engineering** is the starting point for generating desired output from generative AI models.

+- **Craft clear instructions**: Instructions are commonly used in prompts and guide the model's behavior. Be specific and leave as little room for interpretation as possible. Use analogies and descriptive language to help the model understand your desired outcome.

+- **Experiment and iterate**: Prompt engineering is an art that requires experimentation and iteration. Practice and gain experience in crafting prompts for different tasks. Every model might behave differently, so it's important to adapt prompt engineering techniques accordingly.

+## RAG (Retrieval Augmented Generation)

+### Definition

+[RAG (Retrieval Augmented Generation)](../../../ai-studio/concepts/retrieval-augmented-generation.md) is a method that integrates external data into a Large Language Model prompt to generate relevant responses. This approach is particularly beneficial when using a large corpus of unstructured text based on different topics. It allows for answers to be grounded in the organizationΓÇÖs knowledge base (KB), providing a more tailored and accurate response.

+RAG is also advantageous when answering questions based on an organizationΓÇÖs private data or when the public data that the model was trained on might have become outdated. This helps ensure that the responses are always up-to-date and relevant, regardless of the changes in the data landscape.

+### Illustrative use case

+A corporate HR department is looking to provide an intelligent assistant that answers specific employee health insurance related questions such as "are eyeglasses covered?" RAG is used to ingest the extensive and numerous documents associated with insurance plan policies to enable the answering of these specific types of questions.

+### Things to consider

+- RAG helps ground AI output in real-world data and reduces the likelihood of fabrication.

+- RAG is helpful when there is a need to answer questions based on private proprietary data.

+- RAG is helpful when you might want questions answered that are recent (for example, before the cutoff date of when the [model version](./models.md) was last trained).

+## Fine-tuning

+### Definition

+[Fine-tuning](../how-to/fine-tuning.md), specifically [supervised fine-tuning](https://techcommunity.microsoft.com/t5/ai-azure-ai-services-blog/fine-tuning-now-available-with-azure-openai-service/ba-p/3954693?lightbox-message-images-3954693=516596iC5D02C785903595A) in this context, is an iterative process that adapts an existing large language model to a provided training set in order to improve performance, teach the model new skills, or reduce latency. This approach is used when the model needs to learn and generalize over specific topics, particularly when these topics are generally small in scope.

+Fine-tuning requires the use of high-quality training data, in a [special example based format](../how-to/fine-tuning.md#example-file-format), to create the new fine-tuned Large Language Model. By focusing on specific topics, fine-tuning allows the model to provide more accurate and relevant responses within those areas of focus.

+### Illustrative use case

+An IT department has been using GPT-4 to convert natural language queries to SQL, but they have found that the responses are not always reliably grounded in their schema, and the cost is prohibitively high.

+They fine-tune GPT-3.5-Turbo with hundreds of requests and correct responses and produce a model that performs better than the base model with lower costs and latency.

+### Things to consider

+- Fine-tuning is an advanced capability; it enhances LLM with after-cutoff-date knowledge and/or domain specific knowledge. Start by evaluating the baseline performance of a standard model against their requirements before considering this option.

+- Having a baseline for performance without fine-tuning is essential for knowing whether fine-tuning has improved model performance. Fine-tuning with bad data makes the base model worse, but without a baseline, it's hard to detect regressions.

+- Good cases for fine-tuning include steering the model to output content in a specific and customized style, tone, or format, or tasks where the information needed to steer the model is too long or complex to fit into the prompt window.

+- Fine-tuning costs:

+ - Fine-tuning can reduce costs across two dimensions: (1) by using fewer tokens depending on the task (2) by using a smaller model (for example GPT 3.5 Turbo can potentially be fine-tuned to achieve the same quality of GPT-4 on a particular task).

+ - Fine-tuning has upfront costs for training the model. And additional hourly costs for hosting the custom model once it's deployed.

+Earliest retirement date for `gpt-35-turbo` 0301 and 0613 has been updated to August 1, 2024.

+Azure OpenAI Service is powered by a diverse set of models with different capabilities and price points. Model availability varies by region. For GPT-3 and other models retiring in July 2024, see [Azure OpenAI Service legacy models](./legacy-models.md).

+| [GPT-4o & GPT-4 Turbo **NEW**](#gpt-4o-and-gpt-4-turbo) | The latest most capable Azure OpenAI models with multimodal versions, which can accept both text and images as input. |

+| [GPT-4](#gpt-4) | A set of models that improve on GPT-3.5 and can understand and generate natural language and code. |

+## GPT-4o and GPT-4 Turbo

+GPT-4o is the latest model from OpenAI. GPT-4o integrates text and images in a single model, enabling it to handle multiple data types simultaneously. This multimodal approach enhances accuracy and responsiveness in human-computer interactions. GPT-4o matches GPT-4 Turbo in English text and coding tasks while offering superior performance in non-English languages and vision tasks, setting new benchmarks for AI capabilities.

+### How do I access the GPT-4o model?

+GPT-4o is available for **standard** and **global-standard** model deployment.

+You need to [create](../how-to/create-resource.md) or use an existing resource in a [supported standard](#gpt-4-and-gpt-4-turbo-model-availability) or [global standard](#global-standard-model-availability-preview) region where the model is available.

+When your resource is created, you can [deploy](../how-to/create-resource.md#deploy-a-model) the GPT-4o model. If you are performing a programmatic deployment, the **model** name is `gpt-4o`, and the **version** is `2024-05-13`.

+### GPT-4 Turbo

+GPT-4 Turbo is a large multimodal model (accepting text or image inputs and generating text) that can solve difficult problems with greater accuracy than any of OpenAI's previous models. Like GPT-3.5 Turbo, and older GPT-4 models GPT-4 Turbo is optimized for chat and works well for traditional completions tasks.

+## GPT-4

+GPT-4 is the predecessor to GPT-4 Turbo. Both the GPT-4 and GPT-4 Turbo models have a base model name of `gpt-4`. You can distinguish between the GPT-4 and Turbo models by examining the model version.

+- `gpt-4` **Version** `0314`

+- GPT-4 version 0125-preview completes tasks such as code generation more completely compared to gpt-4-1106-preview. Because of this, depending on the task, customers may find that GPT-4-0125-preview generates more output compared to the gpt-4-1106-preview. We recommend customers compare the outputs of the new model. GPT-4-0125-preview also addresses bugs in gpt-4-1106-preview with UTF-8 handling for non-English languages.

+- GPT-4 version `turbo-2024-04-09` is the latest GA release and replaces `0125-Preview`, `1106-preview`, and `vision-preview`.

+> [!IMPORTANT]

+>

+> - `gpt-4` versions 1106-Preview, 0125-Preview, and vision-preview will be upgraded with a stable version of `gpt-4` in the future. Deployments of `gpt-4` versions 1106-Preview, 0125-Preview, and vision-preview set to "Auto-update to default" and "Upgrade when expired" will start to be upgraded after the stable version is released. For each deployment, a model version upgrade takes place with no interruption in service for API calls. Upgrades are staged by region and the full upgrade process is expected to take 2 weeks. Deployments of `gpt-4` versions 1106-Preview, 0125-Preview, and vision-preview set to "No autoupgrade" will not be upgraded and will stop operating when the preview version is upgraded in the region. See [Azure OpenAI model retirements and deprecations](./model-retirements.md) for more information on the timing of the upgrade.

+## What models and regions are available for provisioned throughput?

+> [!NOTE]

+> The provisioned version of `gpt-4` **Version:** `turbo-2024-04-09` is currently limited to text only.

+--model-name gpt-4 \

+Provisioned throughput quota represents a specific amount of total throughput you can deploy. Quota in the Azure OpenAI Service is managed at the subscription level. All Azure OpenAI resources within the subscription share this quota.

+Quota is specified in Provisioned throughput units and is specific to a (deployment type, model, region) triplet. Quota isn't interchangeable. Meaning you can't use quota for GPT-4 to deploy GPT-3.5-Turbo.

+- Larger calls are progressively more expensive to compute. For example, 100 calls of with a 1000 token prompt size will require less capacity than 1 call with 100,000 tokens in the prompt. This also means that the distribution of these call shapes is important in overall throughput. Traffic patterns with a wide distribution that includes some very large calls may experience lower throughput per PTU than a narrower distribution with the same average prompt & completion token sizes.

+### How utilization performance works

+Provisioned deployments provide you with an allocated amount of model processing capacity to run a given model.

+In Provisioned-Managed deployments, when capacity is exceeded, the API will immediately return a 429 HTTP Status Error. This enables the user to make decisions on how to manage their traffic. Users can redirect requests to a separate deployment, to a standard pay-as-you-go instance, or leverage a retry strategy to manage a given request. The service will continue to return the 429 HTTP status code until the utilization drops below 100%.

+### How can I monitor capacity?

+The [Provisioned-Managed Utilization V2 metric](../how-to/monitoring.md#azure-openai-metrics) in Azure Monitor measures a given deployments utilization on 1-minute increments. Provisioned-Managed deployments are optimized to ensure that accepted calls are processed with a consistent model processing time (actual end-to-end latency is dependent on a call's characteristics).

+- You can consider redirecting the traffic to other models, deployments or experiences. This option is the lowest-latency solution because the action can be taken as soon as you receive the 429 signal. For ideas on how to effectively implement this pattern see this [community post](https://github.com/Azure/aoai-apim).

+In the Provisioned-Managed offering, each request is evaluated individually according to its prompt size, expected generation size, and model to determine its expected utilization. This is in contrast to pay-as-you-go deployments which have a [custom rate limiting behavior](../how-to/quota.md) based on the estimated traffic load. For pay-as-you-go deployments this can lead to HTTP 429s being generated prior to defined quota values being exceeded if traffic is not evenly distributed.

+For Provisioned-Managed, we use a variation of the leaky bucket algorithm to maintain utilization below 100% while allowing some burstiness in the traffic. The high-level logic is as follows:

+The number of concurrent calls you can achieve depends on each call's shape (prompt size, max_token parameter, etc.). The service will continue to accept calls until the utilization reach 100%. To determine the approximate number of concurrent calls you can model out the maximum requests per minute for a particular call shape in the [capacity calculator](https://oai.azure.com/portal/calculator). If the system generates less than the number of samplings tokens like max_token, it will accept more requests.

+

+ - Act as a [define role]

+ - Do not perform actions that are not related to [task or topic name].

+ - You use the [insert desired syntax] in your output

+

+ - You will bold the relevant parts of the responses to improve readability, such as [provide example].

+ - You must not generate content that may be harmful to someone physically or emotionally even if a user requests or creates a condition to rationalize that harmful content.

+

+ - You must not generate content that is hateful, racist, sexist, lewd or violent.

+## To Avoid Fabrication or Ungrounded Content in a Q&A scenario

+ - Your answer must not include any speculation or inference about the background of the document or the userΓÇÖs gender, ancestry, roles, positions, etc.

+

+ - Do not assume or change dates and times.

+

+ - You must always perform searches on [insert relevant documents that your feature can search on] when the user is seeking information (explicitly or implicitly), regardless of internal knowledge or information.

+## To Avoid Fabrication or Ungrounded Content in a Q&A RAG scenario

+ - You are an chat agent and your job is to answer users questions. You will be given list of source documents and previous chat history between you and the user, and the current question from the user, and you must respond with a **grounded** answer to the user's question. Your answer **must** be based on the source documents.

+## Answer the following:

+ 1- What is the user asking about?

+

+ 2- Is there a previous conversation between you and the user? Check the source documents, the conversation history will be between tags: <user agent conversation History></user agent conversation History>. If you find previous conversation history, then summarize what was the context of the conversation, and what was the user asking about and and what was your answers?

+

+ 3- Is the user's question referencing one or more parts from the source documents?

+

+ 4- Which parts are the user referencing from the source documents?

+

+ 5- Is the user asking about references that do not exist in the source documents? If yes, can you find the most related information in the source documents? If yes, then answer with the most related information and state that you cannot find information specifically referencing the user's question. If the user's question is not related to the source documents, then state in your answer that you cannot find this information within the source documents.

+

+ 6- Is the user asking you to write code, or database query? If yes, then do **NOT** change variable names, and do **NOT** add columns in the database that does not exist in the the question, and do not change variables names.

+

+ 7- Now, using the source documents, provide three different answers for the user's question. The answers **must** consist of at least three paragraphs that explain the user's quest, what the documents mention about the topic the user is asking about, and further explanation for the answer. You may also provide steps and guide to explain the answer.

+

+ 8- Choose which of the three answers is the **most grounded** answer to the question, and previous conversation and the provided documents. A grounded answer is an answer where **all** information in the answer is **explicitly** extracted from the provided documents, and matches the user's quest from the question. If the answer is not present in the document, simply answer that this information is not present in the source documents. You **may** add some context about the source documents if the answer of the user's question cannot be **explicitly** answered from the source documents.

+

+ 9- Choose which of the provided answers is the longest in terms of the number of words and sentences. Can you add more context to this answer from the source documents or explain the answer more to make it longer but yet grounded to the source documents?

+

+* If you're converting data from an unsupported format into a supported format, optimize the quality of the model response by ensuring the conversion:

+You need to connect to a data source to upload your data. When you want to use your data to chat with an Azure OpenAI model, your data is chunked in a search index so that relevant data can be found based on user queries.

+The [Integrated Vector Database in vCore-based Azure Cosmos DB for MongoDB](/azure/cosmos-db/mongodb/vcore/vector-search) natively supports integration with Azure OpenAI On Your Data.

+For some data sources such as uploading files from your local machine (preview) or data contained in a blob storage account (preview), Azure AI Search is used. When you choose the following data sources, your data is ingested into an Azure AI Search index.

+|Data ingested through Azure AI Search | Description |

+Azure OpenAI On Your Data has intelligent search enabled for your data. Semantic search is enabled by default if you have both semantic search and keyword search. If you have embedding models, intelligent search defaults to hybrid + semantic search.

+If you're using your own index, you'll be prompted in the Azure OpenAI Studio to define which fields you want to map for answering questions when you add your data source. You can provide multiple fields for *Content data*, and should include all fields that have text pertaining to your use case.

+Mapping these fields correctly helps ensure the model has better response and citation quality. You can additionally configure it [in the API](../references/on-your-data.md) using the `fieldsMapping` parameter.

+# [Vector Database in Azure Cosmos DB for MongoDB](#tab/mongo-db)

+* [vCore-based Azure Cosmos DB for MongoDB](/azure/cosmos-db/mongodb/vcore/introduction) account

+* Only vCore-based Azure Cosmos DB for MongoDB is supported.

+* The search type is limited to [Integrated Vector Database in Azure Cosmos DB for MongoDB](/azure/cosmos-db/mongodb/vcore/vector-search) with an Azure OpenAI embedding model.

+

+Use the script provided on [GitHub](https://github.com/microsoft/sample-app-aoai-chatGPT/tree/main/scripts#data-preparation) to prepare your data.

+When you add your vCore-based Azure Cosmos DB for MongoDB data source, you can specify data fields to properly map your data for retrieval.

+* Content data (required): One or more provided fields to be used to ground the model on your data. For multiple fields, separate the values with commas, with no spaces.

+> Automatic index refreshing is supported for Azure Blob Storage only.

+After the data ingestion is set to a cadence other than once, Azure AI Search indexers will be created with a schedule equivalent to `0.5 * the cadence specified`. This means that at the specified cadence, the indexers will pull, reprocess, and index the documents that were added or modified from the storage container. This process ensures that the updated data gets preprocessed and indexed in the final index at the desired cadence automatically. To update your data, you only need to upload the additional documents from the Azure portal. From the portal, select **Storage Account** > **Containers**. Select the name of the original container, then **Upload**. The index will pick up the files automatically after the scheduled refresh period. The intermediate assets created in the Azure AI Search resource won't be cleaned up after ingestion to allow for future runs. These assets are:

+Using Azure OpenAI Studio, you can upload files from your machine to try Azure OpenAI On Your Data. You also have the option to create a new Azure Blob Storage account and Azure AI Search resource. The service then stores the files to an Azure storage container and performs ingestion from the container. You can use the [quickstart](../use-your-data-quickstart.md) article to learn how to use this data source option.

+A small chunk size like 256 produces more granular chunks. This size also means the model will utilize fewer tokens to generate its output (unless the number of retrieved documents is very high), potentially costing less. Smaller chunks also mean the model doesn't have to process and interpret long sections of text, reducing noise and distraction. This granularity and focus however pose a potential problem. Important information might not be among the top retrieved chunks, especially if the number of retrieved documents is set to a low value like 3.

+### Uncited references

+It's possible for the model to return `"TYPE":"UNCITED_REFERENCE"` instead of `"TYPE":CONTENT` in the API for documents that are retrieved from the data source, but not included in the citation. This can be useful for debugging, and you can control this behavior by modifying the **strictness** and **retrieved documents** runtime parameters described above.

+Azure OpenAI On Your Data works by sending instructions to a large language model in the form of prompts to answer user queries using your data. If there is a certain behavior that is critical to the application, you can repeat the behavior in system message to increase its accuracy. For example, to guide the model to only answer from documents, you can add "*Please answer using retrieved documents only, and without using your knowledge. Please generate citations to retrieved documents for every claim in your answer. If the user question cannot be answered using retrieved documents, please explain the reasoning behind why documents are relevant to user queries. In any case, don't answer using your own knowledge."*.

+> The system message is used to modify how GPT assistant responds to a user question based on retrieved documentation. It doesn't affect the retrieval process. If you'd like to provide instructions for the retrieval process, it is better to include them in the questions.

+* For processing the intent: The token estimate for the *intent prompt* includes those for the user question, conversation history, and the instructions sent to the model for intent generation.

+* For generating the response: The token estimate for the *generation prompt* includes those for the user question, conversation history, the retrieved list of document chunks, role information, and the instructions sent to it for generation.

+To troubleshoot failed operations, always look out for errors or warnings specified either in the API response or Azure OpenAI studio. Here are some of the common errors and warnings:

+### Failed ingestion jobs

+*An index with the name X in service Y couldn't be created. Index quota has been exceeded for this service. You must either delete unused indexes first, add a delay between index creation requests, or upgrade the service for higher limits.*

+*Couldn't execute skill because the Web API request failed*

+*Couldn't execute skill because Web API skill response is invalid*

+### 503 errors when sending queries with Azure AI Search

+Each user message can translate to multiple search queries, all of which get sent to the search resource in parallel. This can produce throttling behavior when the number of search replicas and partitions is low. The maximum number of queries per second that a single partition and single replica can support may not be sufficient. In this case, consider increasing your replicas and partitions, or adding sleep/retry logic in your application. See the [Azure AI Search documentation](../../../search/performance-benchmarks.md) for more information.

+* `gpt-4` (0125)

+> Once the GPT4-Turbo with vision preview model is deprecated, you will no longer be able to use Azure OpenAI On your image data.

+description: Learn how to create helpful AI Assistants with tools like Code Interpreter.

+Azure OpenAI Assistants (Preview) allows you to create AI assistants tailored to your needs through custom instructions and augmented by advanced tools like code interpreter, and custom functions. In this article, we provide an in-depth walkthrough of getting started with the Assistants API.

+Code interpreter is available in all regions supported by Azure OpenAI Assistants. The [models page](../concepts/models.md#assistants-preview) contains the most up-to-date information on regions/models where Assistants are currently supported.

+> [!TIP]

+> We've added support for the `tool_choice` parameter which can be used to force the use of a specific tool (like `file_search`, `code_interpreter`, or a `function`) in a particular run.

+An individual assistant can access up to 128 tools including [code interpreter](./code-interpreter.md) and [file search](./file-search.md), but you can also define your own custom tools via [functions](./assistant-functions.md).

+ api_version="2024-05-01-preview",

+- We enable this assistant to access code interpreter with the line `tools=[{"type": "code_interpreter"}],`. This gives the model access to a sand-boxed python environment to run and execute code to help formulating responses to a user's question.

+- In the instructions we remind the model that it can execute code. Sometimes the model needs help guiding it towards the right tool to solve a given query. If you know you want to use a particular library to generate a certain response that you know is part of code interpreter, it can help to provide guidance by saying something like "Use Matplotlib to do x."

+- Since this is Azure OpenAI the value you enter for `model=` **must match the deployment name**.

+Now let's create a thread.

+A thread is essentially the record of the conversation session between the assistant and the user. It's similar to the messages array/list in a typical chat completions API call. One of the key differences, is unlike a chat completions messages array, you don't need to track tokens with
