## TL;DR

- OpenAI is rolling out GPT-5.6 in GitHub Copilot.

---

## Summary

- OpenAI is rolling out GPT-5.6 in GitHub Copilot. The family includes Sol, Terra, and Luna, giving users a choice between maximum reasoning, general-purpose coding, and faster cost-controlled help.
- Sol targets complex work across large codebases and long-running agentic tasks. Terra is the balanced default for everyday interactive and agentic coding, while Luna is the lighter and lowest-cost option.
- The models are being added to Copilot’s model picker across VS Code, Visual Studio, JetBrains, Xcode, Eclipse, Copilot CLI, github.com, GitHub Mobile, the Copilot app, and the cloud agent. Rollout is gradual.
- Sol is available for Pro+, Max, Business, and Enterprise. Terra and Luna also reach Pro users. Business and Enterprise admins must enable access in Copilot settings because the policy is off by default.

## Nauti's Take

This is useful, but it also adds more model-menu overhead. Sol, Terra, and Luna sound neatly segmented, yet the real test is not the naming, it is whether teams can tell when deeper reasoning is worth the extra cost. GitHub’s announcement is PR-heavy and thin on independent performance evidence. The smart move is to set defaults, watch budgets, and avoid burning Sol on routine edits.
