GPT-6.1 Terra arrives in GitHub Copilot at provider list pricing, enabled automatically under the default model policy
Copilot gets an everyday coding model cheaper than Sol. This covers who gets it, how it is billed and whether admins need to act.
// Key points
- Generally available to Copilot Pro, Pro+, Max, Business and Enterprise users, positioned for everyday agentic coding and terminal work at lower cost than GPT-6.1 Sol. In early testing it solved noticeably more terminal and C# coding tasks than GPT-5.6 Terra.
- Billed at provider list pricing under usage-based billing.
- Selectable in the model picker in VS Code, Visual Studio, Copilot CLI, the cloud agent, the Copilot app, github.com, GitHub Mobile, JetBrains IDEs, Xcode and Eclipse, with a gradual rollout.
- Business and Enterprise admins manage it through the model policy. Under default model enablement, new models are turned on automatically unless an admin has turned off the global default or disabled this model.
Builder's takeThis is the first new model since the global default policy from 10-23 took effect: in organizations that never configured it, Terra will simply appear in everyone's picker. I would watch a week of the per-client usage report from 10-25, compare unit cost and merge rate for routine tasks on Sol versus Terra, and only then decide whether to make it the team default.

- Oct 25 The Copilot usage metrics API now breaks usage out by client, listing requests and tokens from Claude Code, Codex, OpenCode and other tools
- Oct 25 GitHub public monitoring adds triage, continuous validity checks, a REST API and webhooks, so enterprises can go after leaked secrets that still work first
