Hello @Benjamin Lamasney

Thank you for reaching out to Microsoft Q&A.

We reviewed the current Microsoft Foundry documentation, but at this time, we could not find an official Microsoft announcement or documentation confirming when the newly released OpenAI Decisions API will be available in Microsoft Foundry. Therefore, we do not have a confirmed Foundry availability date to share.

In general:

Foundry Agent Service is the agent platform available through Microsoft Foundry.

Azure OpenAI model inference APIs, such as the Responses API, are used for model interactions.

A Foundry project endpoint such as .../api/projects/<PROJECT> indicates usage of Foundry Agent Service, while an Azure OpenAI endpoint such as ...openai/v1 is used for Azure OpenAI API operations.

The retirement of the Assistants API and migration to Foundry Agent Service should not be interpreted as confirmation that the new Decisions API is already available in Foundry.

Microsoft currently documents the Responses API as available through Microsoft Foundry. You can refer to the following official documentation:

Microsoft Foundry SDKs and endpoints

Integrate Microsoft Foundry with your applications

Build agents using the Responses API

At this time, we therefore don't have a confirmed timeline for when the Decisions API will be offered through Microsoft Foundry. We recommend monitoring the Microsoft Foundry documentation and service announcements for availability updates.

I Hope this helps. Do let me know if you have any further queries.

Thank you!

There is no published ETA in the provided information for when a newly released OpenAI Decisions API will be available in Foundry.

What is documented is:

Azure OpenAI / Foundry APIs have been moving toward the v1 API model, where new capabilities can be introduced without requiring monthly api-version changes.
Some new API capabilities can appear first as preview features, either through feature-specific preview headers or preview paths.
For Foundry and related services, Microsoft does not generally publish advance rollout dates for specific new capabilities unless they are already announced in product documentation or release notes.
