Hello,

We recently received notice regarding the upcoming deprecation of the 2024-12-01-preview API version for the Azure AI Content Understanding service. We would appreciate clarification on two specific points regarding this deprecation and future API lifecycle tracking:

1. Impact on Azure AI Foundry Models

Does the retirement of this specific Content Understanding API version have any direct or indirect impact on models deployed or utilized within Azure AI Foundry (formerly Azure Machine Learning / Azure OpenAI studio ecosystem)? Specifically, we need to know if any Foundry-specific endpoints, model deployments, or dependent workflows rely on this preview version.

2. Notification Systems for API Version Retirements

While we currently receive alerts regarding model retirement and deprecation timelines, tracking individual API version deprecations across services is more challenging.

Is there a centralized, proactive notification system (such as Azure Service Health alerts or specific Azure Advisor configurations) that we can configure to receive explicit warnings when an API version we are actively calling is scheduled for retirement?

Thank you for your assistance and guidance.

Hello Daniel Kudlowiez Franch,

Welcome to Microsoft Q&A,

The Content Understanding API version deprecation does NOT directly impact Foundry models themselves, but it does affect any workflows that use Content Understanding to call Foundry models.

1. Impact on Azure AI Foundry Models

Content Understanding is a Foundry Tool, not a Foundry Model. The retiring API versions (2024-12-01-preview and 2025-05-01-preview) affect only the Content Understanding service endpoints, not deployments of models like GPT-4.1 or GPT-5.2 in your Foundry resources.

However, Content Understanding depends on Foundry models: all generative capabilities route through your connected Foundry model deployments (GPT-5.2, GPT-4.1, or embedding models). So while the models themselves remain available, your Content Understanding analyzers will stop functioning after July 15, 2026, if you don't migrate to the GA API version (2025-11-01).

Action required: Migrate any Content Understanding analyzers from 2024-12-01-preview or 2025-05-01-preview to the 2025-11-01 GA API by July 15, 2026. See Migrate from Preview to GA.

2. Proactive Notifications for API Version Retirements

Azure provides multiple channels:

  • Azure Service Health Alerts (primary): Configure in Azure Portal > Service Health > Planned Maintenance. Subscribe to updates for "Azure Content Understanding" and similar services. You can set email/SMS alerts per subscription.
  • Azure Advisor Recommendations: Advisor periodically flags deprecated/retiring APIs if they detect usage in your subscription. Enable notifications in Advisor preferences.
  • Official Documentation: Bookmark release notes for services you depend on. Content Understanding What's New prominently displays retirement dates.

For tracking across multiple services, set up a subscription-level service health alert filter by resource type or tag your Content Understanding resources and monitor advisories tied to those tags.

Note: Retirements are sometimes enforced early (precedent: HTTP 410 returned ~4 weeks before the announced date). If you encounter this, file a support request referencing the Service Health advisory ID.

    Hello @Daniel Kudlowiez Franch ,

    Welcome to Microsoft Q&A .Thank you for reaching out to us.

    Thank you for sharing the detailed validation results and observations. Based on the behavior observed, the impact is limited to the retired Azure AI Content Understanding preview API versions and does not indicate an impact to Azure AI Foundry model deployments. The successful response from the GA API version confirms that the resource, endpoint, and authentication configuration are functioning correctly. The required action is therefore focused on API lifecycle migration and dependency validation rather than infrastructure troubleshooting.

    1. Impact of Azure AI Content Understanding API retirement on Azure AI Foundry Models The retirement of Azure AI Content Understanding preview API versions:
      • 2024-12-01-preview
      • 2025-05-01-preview
      does not directly impact Azure AI Foundry model deployments, model endpoints, or model availability. Azure AI Content Understanding and Azure AI Foundry models are separate Azure AI capabilities with independent lifecycle management. The retirement applies specifically to applications, workflows or integrations that directly call the affected Content Understanding API versions. The following Azure AI Foundry capabilities continue to follow their own lifecycle:
      • Azure AI Foundry model deployments
      • Hosted inference endpoints
      • Model catalog availability
      • GPT and embedding model deployments
      • Foundry projects and associated resources
      Workloads expected to require action are those that use Content Understanding APIs, such as:
      • Document processing applications
      • RAG ingestion pipelines where Content Understanding extracts and prepares content
      • Prompt flows or custom applications integrating Content Understanding capabilities
      Some Azure AI Content Understanding capabilities may use generative AI models as part of processing workflows. However, this does not create a dependency where Azure AI Foundry model deployments are retired or impacted when a Content Understanding API version is retired. For solutions combining Content Understanding and Foundry models , only the Content Understanding API integration requires migration. Existing Azure AI Foundry model deployments do not require redeployment or replacement because of this API retirement.
    2. Understanding the HTTP 410 ApiVersionRetired response The response HTTP 410 ApiVersionRetired indicates that the requested API version is no longer available. Since the GA API version (2025-11-01) successfully responds using the same resource and endpoint, the validation confirms:
      1. The Azure AI Content Understanding resource is healthy.
      2. Authentication and authorization are working.
      3. Endpoint configuration is valid.
      4. Network connectivity is not the issue.
      5. The behavior is isolated to the retired preview API versions.
      The current public documentation confirms the retirement of the affected preview API versions. However, public documentation alone cannot confirm whether a specific 410 ApiVersionRetired response was caused by:
      • A planned phased retirement rollout, or
      • An unexpected early enforcement scenario.
    3. Regarding if the retired preview API versions be restored- Restoration of retired preview API versions cannot be guaranteed. Preview APIs:
      • Do not provide the same SLA commitments as Generally Available APIs.
      • May change or retire as services evolve.
      • Should not be used as long-term production dependencies.
      The recommended production approach is:
      1. Treat retired preview API versions as unavailable.
      2. Migrate affected workloads to the supported GA API version.
      3. Complete application validation before production rollout.

    Please check if the following steps help-

    1. Identifying dependencies on retired API versions Please review:
      • Application source code
      • SDK configurations
      • Automation scripts
      • Azure Functions
      • Logic Apps
      • Prompt flows
      • Data pipelines
      • CI/CD pipelines
      • Infrastructure templates
      Search for 2024-12-01-preview 2025-05-01-preview
    2. Confirming endpoint usage Verify whether the application is calling:
      • Azure AI Content Understanding endpoints, or
      • Azure AI Foundry model inference endpoints
      Only Content Understanding API calls using the retired versions require changes.
    3. Updating to the GA API version Update applications and integrations to use 2025-11-01 Review:
      • API request payload changes
      • Analyzer configurations
      • Response processing logic
      • File handling workflows
      • Existing analyzer behavior
    4. Performing regression validation Kindly validate:
      • Existing document types
      • Extraction results
      • Analyzer behavior
      • Confidence and metadata handling
      • Downstream integrations
      • RAG indexing workflows (where applicable)

    Notification options for future API and service retirements

    Azure provides several mechanisms for tracking lifecycle changes. However, there is currently no single service that automatically discovers every API version used by applications and proactively alerts for every API dependency retirement.

    1. Azure Service Health Azure Service Health is the primary mechanism for receiving Azure service retirement notifications. Recommended alert categories:
      • Service retirements
      • Health advisories
      • Planned changes
    2. Azure Updates Azure Updates provides service announcements, retirement communications and lifecycle information.
    3. Azure Advisor Azure Advisor can provide recommendations related to Azure resource lifecycle changes, reliability, security, cost optimization and operational excellence.
    4. API lifecycle guidance for General Azure API lifecycle information

    Please note that - Azure Advisor and the Service Retirement Workbook can help identify supported Azure resource retirement scenarios, but they do not scan application source code, SDK usage, or API calls. Therefore, they should not be considered a complete solution for detecting every API version dependency.

    Thus , to summarise - the retirement of Azure AI Content Understanding preview API versions affects only workloads that directly use those APIs. Azure AI Foundry model deployments, inference endpoints, and model lifecycle processes remain independent and are not impacted by this retirement.

    The suggested approach is:

    Identify applications using:

    • 2024-12-01-preview
    • 2025-05-01-preview

    Migrate affected Content Understanding integrations to:

    • 2025-11-01 GA API version

    Validate application workflows after migration.

    Establish proactive lifecycle monitoring using:

    • Azure Service Health
    • Azure Updates
    • Azure Advisor where applicable
    • Internal API dependency tracking
