At the moment, we're using Claude 3.7 Sonnet - but we're keeping our options open to experiment with other models and potentially bring in a model picker.

(Source: I'm on the product team for Copilot coding agent.)

I was trying to find information on this on the internet and couldn't find any, thanks for providing. Interestingly enough Copilot coding agent on github.com repeatedly could not complete css changes correctly, when I switched to Agent mode in the project IDE with Claude 3.7 it was able to complete it in one round, so I assumed that there was a different model.

Do you at least control the prompt?

In my experience using Claude Sonnet 3.7 in GitHub Copilot extension in VSCode, the model produced hideously verbose code, completely unnecessary stuff. GPT-4.1 was a breath of fresh air.
