Claude Sonnet 4.5 is available in public preview to GitHub Copilot Pro, Pro+, Business, and Enterprise plans.

You’ll now be able to access the model in GitHub Copilot Chat on github.com, GitHub Mobile, VS Code, Visual Studio, JetBrains IDEs, Xcode, and Eclipse through the chat model picker (agent, ask, and edit modes). If you do not yet have access, please check again later.

Enabling access
