GitHub Copilot deprecates Gemini 2.5 Pro and Gemini 3 Flash across every Copilot surface
- Sources: primary, discussion
- Summary: GitHub removed Gemini 2.5 Pro and Gemini 3 Flash from every Copilot surface. The change log states the deprecation is effective the same day with no grace period.
- Why it matters: The suggested replacement models are not automatically available, because Copilot Enterprise administrators may need to enable them in model policy first.
