GPT-5.6 comes in three variants, Sol, Terra, and Luna, so you can match the model to the job, whether that’s reasoning over a large codebase, everyday agentic coding, or fast, cost-efficient assistance. - GPT-5.6 Sol: The highest reasoning ceiling in the family. Best for complex reasoning over large codebases and demanding, long-running agentic work. - GPT-5.6 Terra: The balanced default. A strong all-round choice for everyday interactive and agentic coding. - GPT-5.6 Luna: A lightweight, cost-efficient variant for smaller, faster tasks and also the lowest-cost option in the family. These models are billed at provider list pricing under Usage Based Billing. See [GitHub Copilot’s pricing for models and requests](https://docs.github.com/copilot/reference/copilot-billing/models-and-pricing) for details.
