GitHub retires one Copilot model
GitHub deprecated MAI-Code-1-Flash across all Copilot experiences on September 10, replacing it with MAI-Code-1.1-Flash. The changelog says the switch covers Copilot Chat, inline edits, ask and agent modes, and code completions; Enterprise administrators may need to enable the replacement through model policies. Teams tracking Copilot workflow costs should check fallback-model access before a deprecated model disappears from their policy surface.
