GPT-6.1 Terra is now generally available in GitHub Copilot

GitHub says GPT-6.1 Terra, OpenAI's newest model, is generally available in GitHub Copilot. GitHub describes it as built for everyday agentic coding and terminal work at a lower cost than GPT-6.1 Sol, and says that in early testing it solved noticeably more terminal and C# coding tasks than GPT-5.6 Terra, working in focused, consolidated steps on well-scoped tasks.

• Plans: Copilot Pro, Pro+, Max, Business and Enterprise.
• Where: the model picker in Visual Studio Code, Visual Studio, Copilot CLI, the Copilot cloud agent, the GitHub Copilot app, github.com, GitHub Mobile, JetBrains IDEs, Xcode and Eclipse. Rollout is gradual.
• Billing: provider list pricing under usage-based billing.
• Admins: Business and Enterprise administrators control access through the model policy; under default model enablement, new models are turned on unless the global default is off or the model is disabled.
