Claude Sonnet 4.5 is generally available to Copilot Enterprise, Copilot Business, Copilot Pro, and Copilot Pro+ customers.

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

Enabling access within Copilot Chat and IDE

Copilot Business and Copilot Enterprise administrators must opt in by enabling the new Claude Sonnet 4.5 policy in Copilot Chat and IDE settings. Once enabled, users in that organization will see the models in the model picker across all supported IDEs.

For individual plans, enable Claude Sonnet 4.5 by selecting it in the model picker in any supported IDE and confirming the one-time prompt.

Copilot coding agent

Copilot coding agent will also now use Claude Sonnet 4.5 for all subscription types, regardless of your Copilot Chat and IDE settings.
