What article on docs.github.com is affected?

https://docs.github.com/en/copilot/reference/ai-models/how-copilot-serves-ai-models

What part(s) of the article would you like to see updated?

Ensure all models are included in this list, as under OpenAI only o3 and o4-mini are listed.
If 4.1 and 4o are served only by Github through Azure (and never OpenAI) it should still be indicated

@Cubox This is another one we're going to work on internally with the team who helped with the article as it stands, so I'm going to transfer it to an internal issue. Thanks again for bringing it up!
