Summary
GitHub Copilot will deprecate select AI models on October 2nd, 2026, impacting all Copilot experiences. Users and administrators must update workflows and integrations to supported models before this date. Copilot Enterprise and Business administrators need to enable alternative models via Copilot settings to ensure continued access. This change affects how developers interact with AI-powered coding assistance.
Why it matters
Why it matters: Microsoft is phasing out older AI models for GitHub Copilot. This affects all users, especially administrators of Copilot Business and Enterprise, who must actively reconfigure model policies. The company aims to streamline its offerings and push users toward newer, presumably more capable, models. Competitors like OpenAI and Google Gemini also regularly update their model offerings. Developers should monitor Copilot's documentation for supported models and plan migration. The focus is on ensuring a smooth transition to the latest AI capabilities within the developer toolset.
