Add base_url override support, to allow changing the OpenAI endpoint.

[joshuataylor]

The OpenAI Python library allows overriding the base_url when defining the client.

It would be great if we could do this on a config level, where api_url in ExOpenAI.Config could be defined in config like this:

config :ex_openai,
  base_url: System.get_env("OPENAI_BASE_URL"),

Then it would override the base_url.

Let me know what you think of this, happy for any changes, it's a pretty basic change, so do what you think is best :).

+1 for this. There are a lots of openapi compatible services out there.

Interesting, I didn't know such a use case exists. Thanks for the PR! lGTM

Any ETA on merging this PR?

[dvcrn]

Slipped through the cracks, whoops!

[Tonyhaenn]

Woot! Thanks for the speedy turnaround.

Big thanks to @joshuataylor for the original PR

I want to cut a new release after changes (if any) required for the new gpt-4o model, will try to get around it soon-ish

[Tonyhaenn]

Thank you! I read that GPT4o right now is only supporting text input / output for now. The new AV input/output would be rolled out in the coming months.

I'm building an app that's going to use both Gpt4 and llama3, so eager to see this go live :)
