GitHub Copilot integrates OpenAI's GPT-5.6 family
GitHub Copilot is rolling out OpenAI's GPT-5.6 family, featuring Sol, Terra, and Luna variants tailored for different coding tasks, from complex codebase reasoning to cost-efficient assistance. These models are available under Usage Based Billing and will be accessible through various Copilot SKUs and IDE integrations, though gradual rollout means availability may vary. Administrators must manually enable the new models in Copilot settings.
- →GPT-5.6 Sol model for complex codebase reasoning
- →GPT-5.6 Terra model for balanced coding assistance
- →GPT-5.6 Luna model for cost-efficient tasks
- →Expanded model selection in GitHub Copilot integrations
- →Gradual rollout and administrator enablement required
Features (3) ›
- GPT-5.6 Sol model for complex codebase reasoning
The GPT-5.6 Sol variant offers the highest reasoning ceiling, optimized for complex analysis of large codebases and demanding agentic coding tasks.
- GPT-5.6 Terra model for balanced coding assistance
GPT-5.6 Terra is presented as a balanced, all-round choice suitable for everyday interactive and agentic coding tasks.
- GPT-5.6 Luna model for cost-efficient tasks
The GPT-5.6 Luna variant is a lightweight and cost-efficient option designed for smaller, faster tasks, representing the lowest cost within the family.
Enhancements (1) ›
- Expanded model selection in GitHub Copilot integrations
Users will be able to select GPT-5.6 models via the model picker in various GitHub Copilot integrations including IDEs like VS Code and JetBrains, Copilot CLI, web interface, and mobile apps.
Notes (1) ›
- Gradual rollout and administrator enablement required
The new GPT-5.6 models are rolling out gradually, and Copilot Enterprise and Business plan administrators must explicitly enable the policy for these models in Copilot settings, as it is off by default.
