OpenAI’s GPT-6 Sol and GPT-6 Luna now available

OpenAI’s GPT-6 family is expanding in GitHub Copilot with two additional models: GPT-6 Sol, and GPT-6 Luna. Joining the previously released GPT-6 Astra, these new options let you select the model that best fits your task, whether that’s everyday agentic coding or fast, cost-efficient assistance.

• GPT-6 Sol: A balanced model for interactive and agentic coding. A strong all-round choice for development tasks that benefit from careful, multistep validation.
• GPT-6 Luna: A lightweight, cost-efficient model for smaller, faster tasks and the lowest-cost option in the GPT-6 family.

These models are billed under usage-based billing. See pricing for GitHub Copilot models and requests for details.

GPT-6 Sol is available to Copilot Pro+, Max, Business, and Enterprise plans. GPT-6 Luna is available to Copilot Pro, Pro+, Max, Business, and Enterprise plans.

You can select the models in the model picker in:

• Visual Studio Code
• Visual Studio
• Copilot CLI
• GitHub Copilot cloud agent
• GitHub Copilot app
• github.com
• GitHub Mobile iOS and Android
• JetBrains
• Xcode
• Eclipse

Rollout will be gradual. Check back soon if you don’t see the models yet.

Copilot Enterprise and Copilot Business plan administrators can manage access to GPT-6 models through the model policy in Copilot settings. Under default model enablement, new models are enabled automatically unless an administrator has turned off the global default or explicitly disables this model.
