support for responses.create() with AzureOpenAI and AsyncAzureOpenAI

Hi OpenAI team 👋

We’ve noticed that, as of now, the AzureOpenAI and AsyncAzureOpenAI clients do not expose the .responses resource like the default OpenAI client does. This is a bit limiting, especially considering that Azure OpenAI has recently added support for the /openai/responses endpoint as part of the 2025-03-01-preview API version.

Currently, attempting to use:

client = AsyncAzureOpenAI(...)
await client.responses.create(...)

raises an AttributeError because .responses is not available on that class.

It would be great if .responses was added to AzureOpenAI and AsyncAzureOpenAI, similarly to how .chat.completions are exposed.

• Azure now supports /openai/responses endpoint
• model / deployment ID is passed in the JSON body, not in the path
• No need to add it to _deployments_endpoints
• Adding this would make the SDK consistent and easier to use for Azure users

Thanks in advance! Happy to contribute a PR if you’re open to it.

Best,
Nikolai

Hi there,

check code below once

client = AsyncAzureOpenAI(...)
await client.responses.create(...)
results in an AttributeError because the .responses property isn't available.

Since Azure now supports the /openai/responses endpoint (using the 2025-03-01-preview API version), it makes sense to add this feature. It would align the behavior of these clients with how .chat.completions is implemented, making everything more consistent. Plus, because the model/deployment ID is passed in the JSON body instead of the endpoint path, integrating this shouldn't require major changes.

Overall, this enhancement would make the client more user-friendly for Azure users. Thanks again for proposing this improvement, and it's great to know you're willing to help with a PR if needed!

@NikGor, @kiranimmadi2, which version of the openai library are you encountering this with? Azure support for /responses should certainly be present; basic Azure OpenAI use of the synchronous client is documented on learn.microsoft.com and I just validated the following quick modification to use the async client with 1.74.1 (and an earlier 1.69.0 environment for a positive comparison):

import asyncio
import os
from openai import AsyncAzureOpenAI

async def main():
    client = AsyncAzureOpenAI(
        api_key=os.getenv("AZURE_OPENAI_API_KEY"),  
        api_version="2025-03-01-preview",
        azure_endpoint = os.getenv("AZURE_OPENAI_ENDPOINT")
        )

    response = await client.responses.create(
        model="gpt-4o-mini", # replace with your model deployment name 
        input="This is a test."
        #truncation="auto" required when using computer-use-preview model.
    )

    print(response.output[0]);

asyncio.run(main())
