GitHub recommends newer alternatives and says enterprise administrators may need to enable them.","body":"GitHub has deprecated six model options across most GitHub Copilot experiences, effective Oct. 19, 2026. The change covers Copilot Chat, inline edits, ask and agent modes, and code completions, the company said.\n\nThe retired models are Gemini 3.7 Flash, GPT-5.5, GPT-5.4, GPT-5.4 mini, GPT-5 mini and Grok 4.5. GitHub recommends Gemini 3.8 Flash as a replacement for Gemini 3.7 Flash; GPT-6.1 Sol for GPT-5.5 and GPT-5.4; GPT-6 Luna for both smaller GPT-5 models; and Grok 4.7 for Grok 4.5.\n\nGitHub said the deprecations were announced on Sept. 18. Copilot Enterprise administrators may need to enable access to the replacement models through model policies in Copilot settings. Once enabled, the alternatives should appear in the Copilot Chat model selector in VS Code and on GitHub.com. Customers do not need to take any action to remove the deprecated models, the company said.\n\nThe announcement applies to most Copilot experiences; GitHub's notice does not say the models are being removed from every product or service. It directs enterprise customers with questions to their account managers.","content_kind":"author_paraphrase","explanation":{"feature":"The models were deprecated across most Copilot experiences on Oct. 19.
