Clarification about retirement/deprecation of Azure OpenAI On Your Data Extension

[arnabbiswas1]

The latest model that Azure OpenAI's On-Your-Data extension supports is GPT-4o (link). Considering gpt-4o (2024-11-20) is retiring on 2026-06-03,

• There needs to be a declaration if On-Your-Data is also retiring on that date.
• If yes, there needs to be a documented migration path from On-Your-Data to Foundry-Agent-Service.

There is some discussion happening on a different repository (one, two: closed issue). Hence, creating a new issue here.

Open queries about the topic of migration:

• Looks like On-Your-Data works with gpt-4.1, gpt-4.1-mini although the relevant documentation states that these two models are not supported (one, two). In case, gpt-4.1 is declared as a supported model, the retirement date for On-Your-Data shifts to 2026-10-14 (4.1 retirement date) from 2026-06-03 (4o retirement date).
• In the other thread, Foundry Agent Service along with Foundry IQ/Azure AI Search has been recommended as the alternative for On-Your-Data (link). However,

  • The Azure AI Projects client library for Python exposing the Responses API is still in Beta (2025-11-15-preview)

  • Foundry IQ is also in Beta

Considering the there is lesser than 6 months of time for the migration and not all the services/APIs are not in GA/Stable, a quick response would be appreciated.
