- GitHub Copilot usage API separates local BYOK and enterprise custom model metrics
GitHub’s changelog says the Copilot usage metrics API now breaks out bring-your-own-key usage from Copilot-hosted models. Local BYOK covers developer-configured provider keys and local models (for example Ollama, Foundry Local, LM Studio, llama-server) via used_local_byok, totals_by_local_byok, and active local BYOK user counts. Enterprise custom models configured in GitHub settings get is_custom_enterprise_model on totals_by_client model entries, observed server-side across clients including IDEs. Existing aggregate totals are unchanged; there is no backfill for earlier report days.
- GitHub deprecates six models in Copilot, including GPT-5.5, GPT-5.4 and Grok 4.5, as of Oct. 19
As of Oct. 19, GitHub has deprecated Gemini 3.7 Flash, GPT-5.5, GPT-5.4, GPT-5.4 mini, GPT-5 mini and Grok 4.5 across most GitHub Copilot experiences, including Copilot Chat, inline edits, ask and agent modes, and code completions. GitHub suggests Gemini 3.8 Flash, GPT-6.1 Sol, GPT-6 Luna and Grok 4.7 as replacements; the deprecations were announced on Sept. 18. Copilot Enterprise administrators may need to enable the alternative models through their model policies.
- GitHub will retire Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra from Copilot on November 16, pointing users to Opus 5.5, GPT-6.1 Sol or GPT-6 Luna
GitHub says Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra will leave every Copilot experience—including Chat, inline edits, ask and agent modes, and completions—on November 16, 2026, with Claude Opus 5.5, GPT-6.1 Sol or GPT-6 Luna as suggested replacements. Claude Opus 4.8 stays available to individual Copilot subscribers on annual plans so they keep an Opus option. Under default model enablement, Copilot Enterprise and Business get the alternatives automatically unless an admin turned off the global default or disabled the model.
- Gemini 4 Argon is now generally available in GitHub Copilot
GitHub says Google's Gemini 4 Argon is now generally available in GitHub Copilot for Pro+, Max, Business and Enterprise users, selectable in VS Code, Visual Studio, Copilot CLI, the Copilot coding agent, the GitHub Copilot app, JetBrains IDEs, Xcode and Eclipse, with a gradual rollout. GitHub says Argon solved more tasks than previous Gemini models on every coding benchmark in its early testing, with the largest gains in Copilot CLI. It is billed at provider list pricing under usage-based billing, and Business and Enterprise admins control access through model policy.
