Confirm this is an issue with the Python library and not an underlying OpenAI API

Describe the bug

Hi,

I am using response api with image generation tool. I want to limit number of images as 1. But could not find the correct parameter for the response api tool. Is there any parameter that limits the number of images while using response api?

https://platform.openai.com/docs/guides/image-generation?image-generation-model=gpt-image-1#customize-image-output

Thanks,

To Reproduce

Create a Azure Openai client.
run client with responses api.

Code snippets

from openai import OpenAI
client = OpenAI()
response = client.responses.create(
                        model="gpt-4.1-mini",
                        input=input_data,
                        tools=[{"type": "image_generation", "quality": "medium", "size":"1024x1024",  "n": 1 }],
                    )
