   This issue might be a duplicate of or closely related to existing issues. Please check:

   • fix(copilot): claude-sonnet-4.6 max reasoning effort not available; model key mismatch on refresh #33607: Claude models via GitHub Copilot have reasoning effort limitations and model key mismatches that affect thinking/reasoning display

   If the thinking feature works with other providers but not GitHub Copilot specifically, the root cause may be the Copilot-specific reasoning effort handling described in #33607.
