On March 31, 2029, Microsoft will retire the following eight Azure AI Language features:
- Key Phrase Extraction
- Sentiment Analysis and Opinion Mining
- Custom Text Classification
- Conversational Language Understanding (CLU)
- Custom Question Answering (CQA)
- Orchestration Workflow
- Summarization (extractive and abstractive, for documents and conversations)
- Entity Linking.
After this date, requests to these features will return errors. The related authoring and runtime capabilities in Language Studio, Microsoft Foundry, and via REST APIs will no longer be available.
Customers are encouraged to begin planning migrations ahead of time using supported alternatives in Microsoft Foundry, which provides a unified experience for managing AI models and workloads. Other Azure AI Language features, including Language Detection, PII Detection, Text Analytics for Health, Prebuilt NER, and Custom NER, will continue to be supported.
