→
New stateOn 2 October 2026, GitHub will deprecate the four models across Copilot Chat, inline edits, ask and agent modes, and code completions. GitHub suggests Gemini 3.8 Flash, Kimi K3 and Claude Opus 5 as replacements.

Who is affected

GitHub Copilot users, workflows and integrations that explicitly select one of the four retiring models, plus Business and Enterprise administrators whose model policies govern alternative access.

Action required

Move workflows and integrations to a supported alternative before 2 October 2026 and verify that the chosen replacement is available and enabled in the applicable organization or enterprise policy.

Evidence boundary

GitHub proves the retirement date, affected models, Copilot surfaces and suggested alternatives. A suggestion is not represented as universal entitlement or immediate availability; administrators may need to enable alternatives, and no manual removal action is required after deprecation.
