GPT-6.1 Terra is generally available in GitHub Copilot

GitHub says GPT-6.1 Terra is now generally available in GitHub Copilot for Pro, Pro+, Max, Business and Enterprise users, aimed at everyday agentic coding and terminal work at a lower cost than GPT-6.1 Sol. In early testing, GitHub says it solved noticeably more terminal and C# coding tasks than GPT-5.6 Terra. You can pick it in the model picker across Visual Studio Code, Visual Studio, Copilot CLI, cloud agent, the Copilot app, github.com, GitHub Mobile, JetBrains, Xcode and Eclipse; rollout is gradual. It is billed at provider list pricing under usage-based billing, and Business and Enterprise admins can manage access in Copilot model policy settings.
