Azure / OpenAI Responses API Tools Parity Tracking

[tsuzaki430]

Description

This issue tracks feature parity specifically for Responses API tools
between the OpenAI and Azure providers.

The goal is to:

• Keep @ai-sdk/azure aligned with @ai-sdk/openai where tool capabilities allow.
• Clearly document platform-level limitations in Microsoft Foundry (Azure OpenAI platform).
• Track open PRs that improve Azure tool support.

This issue also serves as preparation for future Microsoft Foundry
feature updates, enabling the Azure provider to adopt new
tool capabilities with minimal delay.

I’ve reviewed most of the PRs from the list — great stuff, @tsuzaki430 .
I ran into an issue with file uploads: when the Container tool is enabled in Azure, PDF uploads sometimes hang, and no response is returned.
I reproduced this in Agent with Code Interpreter enabled as well. I uploaded a PDF, but never got a response.
Any idea what might be causing this?

@rahulbhadja

Thanks for reporting this — we’re seeing something very similar.

In our app, PDF uploads as vision can fail or hang when code_interpreter is configured with an explicit containerId. I initially thought it was an integration bug on our side, but since you reproduced it in Agent with Code Interpreter enabled, it may be a platform-level issue.
