Question

GPT-5.2-Chat on Azure Foundry doesnt support tools

Deep Mehta 0 Microsoft Employee

The Azure Portal says that gpt-5.2-chat is supposed to support tools, but when I add it to my agent, I get a popup saying this model doesnt support tools and all tools will be removed

I understand
But I think this is a bug

Reason I am saying this is, I have an agent with gpt-5.2-chat configured and is able to use OpenAPI tool call
It's just the new agents aren't letting me do the same

This makes me believe that gpt-5.2-chat should support this as it is capable of doing so

Hi Team,

We are facing similar issue while using CrewAI Agentic framework and Azure gpt-5.2 chat/completions API.

The custom tool is not being invoked by agent/task defined in crew for Azure gpt-5.2. We have given a file path argument to custom tool and to extract document content using custom tool from the file path.

This is the error we are facing:

2026-04-10 15:32:20,947 - 16736 - agent_job_utils.py-agent_job_utils:114 - INFO: [CrewAI Progress] Agent: Document Extractor, Task: Use the 'DocumentExtractorTool' to read the uploaded document from C:\Users\glkindra\AppData\Local\Temp\tmpqi2hpfa0.docx.

The document may be Excel, PDF, Word, PowerPoint, CSV, or text.

Extract the full content of the document.

, Status: completed, Output: {"error":"File not found or inaccessible","path":"C:\Users\glkindra\AppData\Local\Temp\tmpqi2hpfa0.docx","extracted_content":null}.

Is this behaviour expected?

Hi Deep Mehta,

What you’re seeing is expected behavior with gpt‑5.2‑chat in Azure AI Foundry right now, and it’s a bit confusing because of how the portal labels capabilities.

Although the model catalog and portal description mention “agent / tool” scenarios, gpt‑5.2‑chat does not currently support tools when used inside Foundry agents. When you attach the model to an agent, Foundry correctly warns you and removes any configured tools. That warning is accurate and reflects the current runtime behavior, not a misconfiguration on your side.

A few important clarifications:

• The model itself supports tool‑style reasoning in some contexts, but

• The Foundry Agents execution path does not yet enable tool calling for gpt‑5.2‑chat

• This is why tools work with models like GPT‑4.1 or earlier GPT‑5 variants, but are disabled for gpt‑5.2‑chat in agents

• The portal text is ahead of the current Foundry agent runtime support

So there’s nothing broken in your setup. This is a feature gap, not a permissions or configuration issue.

Current practical options:

• If your agent requires tools or function calling, continue using GPT‑4.1 or another tool‑enabled model

• Use gpt‑5.2‑chat for chat‑only or multimodal scenarios where tools are not required

• If you’re calling the Responses API directly (outside Foundry Agents), you may see different capabilities than what Agents currently support

At the moment, there’s no published timeline in Microsoft Learn documentation for when gpt‑5.2‑chat tool support will be enabled in Foundry agents.

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

Thankyou!
