Introduction

GitHub Copilot Pro and GitHub Copilot Pro+ users can select the model used by Copilot coding agent.

Note

Model selection for Copilot coding agent is only supported when starting a task from the agents tab or panel, assigning an issue to Copilot on GitHub.com and from the Raycast launcher. See Asking GitHub Copilot to create a pull request.

You may find that different models perform better, or provide more useful responses, depending on the type of tasks you give Copilot.

Support for selecting a model is coming soon for GitHub Copilot Business and GitHub Copilot Enterprise users. Until then, for these users, Copilot coding agent will use Claude Sonnet 4.5. GitHub reserves the right to change the model used at any time.

Supported models

The following options are currently available:

  • Auto
  • Claude Sonnet 4.5
  • GPT-5.1-Codex-Max
  • Claude Opus 4.5

Note

If you select Auto, Copilot auto model selection will select the best model based on availability and to help reduce rate limiting. See About Copilot auto model selection.
