Feature hasn't been suggested before.

  • I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

It looks like Reasoning/Thinking doesn't work with Copilot. /thinking makes no effect even when using models that have variants.

Adding a separate issue to tracks this.

This issue might be a duplicate of existing issues. Please check:

  • #6864: No reasoning at all through Github Copilot provider (exact same issue)
  • #8838: Reasoning process not displayed when using GitHub Copilot with models that support reasoning
  • #5866: GitHub Copilot routing through Chat API instead of Responses API (likely root cause preventing reasoning parameters)
  • #4803: Question about how thinking works with GitHub Copilot
  • #8167: Feature request for keybind to toggle thinking visibility (/thinking)

Feel free to ignore if none of these address your specific case.
