feat(provider/azure) : enable codeInterpreter and fileSearch for AzureOpenAI

[tsuzaki430]

Background

The built-in tool 'code_interpreter' and 'file_search' are enabled on Azure OpenAI Responses API.

tool/provider	OpenAI	Azure OpenAI
web_search	✅ Enabled	❌ Not currently supported
code_interpreter	✅ Enabled	✅ Enabled
file_search	✅ Enabled	✅ Enabled

note : currently, web_search is not supported in Azure OpenAI provider.
https://learn.microsoft.com/en-us/azure/ai-foundry/openai/how-to/responses?tabs=python-secure#model-support

Summary

Azure provider's code_interpreter and file_search is enabled same as openai provider.
openai's tools code_interpreter and file_search are added to internal export (packages/openai/src/internal/index.ts).
And azure's tools get the implementations from import openai provider's tools.

azure.tools.fileSearch build-in tool will be available.

const result = await generateText({
  model: azure.responses('gpt-4.1-mini'),
  prompt: 'What does the document say about user authentication?',
  tools: {
    file_search: azure.tools.fileSearch({
      // optional configuration:
      vectorStoreIds: ['vs_123', 'vs_456'],
      maxNumResults: 10,
      ranking: {
        ranker: 'auto',
      },
    }),
  },
  // Force file search tool:
  toolChoice: { type: 'tool', toolName: 'file_search' },
});

azure.tools.codeIinterpreter build-in tool also will be available.

const result = await generateText({
  model: azure.responses('gpt-4.1-mini'),
  prompt: 'Write and run Python code to calculate the factorial of 10',
  tools: {
    code_interpreter: azure.tools.codeInterpreter({
      // optional configuration:
      container: {
        fileIds: ['assistant-123', 'assistant-456'], // optional file IDs to make available
      },
    }),
  },
});

Manual Verification on Azure

✅code_interpreter works.
✅code_interpreter with fileIds "assistant-" prefix files.
✅file_search works is "vs_" vector store.
✅both openai and azure providers , I tried same test and get almost the same result.

Others

I met the file_search zod parse error on openai and azure provider both environments.
#8030 (comment)
When it will be fixed on openai , I think azure's tool will be fixed , too.

My own review finished. Thank you.

Hi @tommasoghisini and @jephal I've seen you reacting to the PR. Can you confirm that the codeInterpreter and fileSearch is working with @tsuzaki430's changes? I have trouble with my own local test environment and Azure right now. I'd like to get this shipped though 😁

[gr2m]

@tsuzaki430 thank you for another great pull request! Changes look great, I just need to confirm it's working as it should, or have someone else confirm.

Could you please add two examples for the Code Interpreter and File Search features? You can use https://github.com/vercel/ai/blob/861fb35ccd8557959f8804230aacca07ba9f8bd3/examples/ai-core/src/generate-text/azure.ts as a template

Hi @gr2m @tsuzaki430, tested locally with a generateText call and got a few errors:

1. when calling with 2 vectorstores it only gives a response based on the last one passed in the array, and doesn't read the first value. (2 vectorstores are max but this seems to be by design). Also i get this warning AI SDK Warning: tool result parts in assistant messages are not supported for OpenAI responses

2. when running code-interpreter i get a type error. in the output response i get a response of type 'code_interpreter_call', could this be as it doesnt match any of the message parts/types 'text', 'tool_call' etc?
   "output": [ { "id": "ci_12345", "type": "code_interpreter_call", "status": "completed", "code": "# Generate and execute a Python script that counts Fibonacci numbers up to 1000\

Hello , dear @gr2m 😊
Thank you for your daily maintenance of the AI ​​SDK.
I recently encountered a conflict, but fixed it and it now works as expected.
We're really looking forward to seeing file-search and code-interpreter working with the AI ​​SDK on Azure!🚀
Could you please review this PR when you have time?✨

[gr2m]

Let's go, thank you all!

[gr2m]

@tommasoghisini @tsuzaki430 @jephal I'm looking into creating a @vercel/ai-sdk-azure team. It would be our first community maintainer team. Would any of you be interested to help out? No expectations, it's just an experiment at this point. But the idea is that we would prioritize pull requests for the azure provider that is either created or approved by a member of the @vercel/ai-sdk-azure team

[rahulbhadja]

@gr2m , we've been using Azure OpenAI for the past 2 years and would be happy to contribute to the ai-sdk project. We're also currently using @ai-sdk/azure in our application, so I'd be glad to contribute and help improve the Azure integration as well.

[tsuzaki430]

@gr2m

Hello,
Thank you for review and new release.

Would any of you be interested to help out?

Yes, maybe I can do something help.
Thank you for your message.
I like think of AI SDK.

[tommasoghisini]

@gr2m I really like the idea. Support for the Azure provider is key for us, so I'm more than happy to help out.

Thanks for putting this together!

[jephal]

@gr2m Sounds great, Azure support for AI-sdk is very important to our team :)

[gr2m]

@rahulbhadja @tsuzaki430 you should have gotten invitations.

@tommasoghisini @jephal coming soon, thank you for offering to help!

[rahulbhadja]

Hi @gr2m , I got the invite but it's asking for Okta login that I don't have, and not able to reset pass. Can you help me with it? Thanks!

[tsuzaki430]

Hello,
Thank you for invite.
Same as Rahul , I don't have Okta login.
So I couldn't input correct username and password.

[gr2m]

Sorry for that! It's the first time that @vercel is inviting external contributors. I'll find out if we can disable the Okta login for you

[tsuzaki430]

@gr2m
Hello , I received the invite and finished successfully.
Thank you and I want to contribute for @ai-sdk/azure , AI SDK.

[gr2m]

great, thank you for confirming. You should all have been invited by now, and shouldn't need an Okta login.

[jephal]

Hi @gr2m, does that include @tommasoghisini and I? I cannot see an invite anywhere

[gr2m]

Hi all, apologies but while we were able to create the @vercel/ai-sdk-azure team, it turns out we cannot add external collaborators to it. I've been thinking what else I could do to keep everyone interested in the loop.

For now, I created an issue that we can utilize to communicate:
#9863

Hi @gr2m, does that include @tommasoghisini and I? I cannot see an invite anywhere

sorry not sure what happened. Can you see if https://github.com/vercel/ai/invitations works for you know?

[tommasoghisini]

Hi @gr2m, I believe the invite now worked :)

Will use #9863 to coordinate

Thanks!
