GitHub will deprecate MAI-Code-1-Flash across Copilot on 10 September 2026

GitHub will deprecate MAI-Code-1-Flash across all GitHub Copilot experiences on 10 September 2026 and recommends MAI-Code-1.1-Flash as the replacement, with enterprise model policy potentially required before users can select the replacement.

Deprecation scheduled

Commercial transition

Previous stateMAI-Code-1-Flash remained selectable in supported GitHub Copilot experiences subject to account and policy availability.
→
New stateOn 10 September 2026 GitHub plans to deprecate MAI-Code-1-Flash across Copilot, with MAI-Code-1.1-Flash named as the suggested alternative and enterprise administrators potentially needing to enable the replacement model through model policy.

Who is affected

GitHub Copilot users and administrators whose workflows select MAI-Code-1-Flash or whose enterprise policies govern replacement-model access.

Action required

Locate workflows and user guidance that depend on MAI-Code-1-Flash, test MAI-Code-1.1-Flash or another supported model, and verify enterprise model policy permits the chosen replacement before 10 September.

Evidence boundary

GitHub proves the 10 September MAI-Code-1-Flash deprecation and suggests MAI-Code-1.1-Flash. It does not establish a price change, guarantee replacement access for every account without rollout or policy requirements, or imply other Copilot models share the same retirement date.
