Selected GitHub Copilot models deprecated (github.blog)

GitHub has announced the deprecation of several models for GitHub Copilot, effective September 1, 2026. This includes prominent models such as Gemini 3.1 Pro and multiple versions of Claude Opus and Claude Sonnet. Users are encouraged to transition to newer alternatives, including Gemini 3.7 Flash and Claude Sonnet 5, to ensure continuity and access to updated features within Copilot experiences, which encompass chat, inline edits, and code completions. This move is significant for the AI/ML community as it reflects GitHub's commitment to providing users with enhanced tools that incorporate the latest advancements in machine learning. The shift also requires Copilot Enterprise administrators to adjust their settings to enable access to the newly supported models. This proactive step emphasizes the importance of keeping AI tools up-to-date, facilitating smoother integration and improved performance for developers.
