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

• This is an issue with the Python library

Describe the bug

httpx 0.28.0 removed proxies in httpx.Client, result in error:

  File ".../test.py", line 3, in <module>
    client = OpenAI(
        api_key="API_KEY",
        base_url="https://some_url/v1",
    )
  File ".../lib/python3.13/site-packages/openai/_client.py", line 123, in __init__
    super().__init__(

    super().__init__(**kwargs)

TypeError: Client.__init__() got an unexpected keyword argument 'proxies'

To Reproduce

With a python file with the following content can reproduce the error:

from openai import OpenAI

client = OpenAI(
    api_key="API_KEY",
    base_url="https://some_url/v1",
)

I just found it is already fixed with the most recent openai package.
Sorry for the trouble.
