One-million-token context windows; configurable reasoning levels

GitHub Copilot now supports larger context windows and configurable reasoning levels to help you tackle deeper, more complex work.

Leverage one-million-token context windows

A one-million-token context window means users can now work across larger codebases, longer documents, and complex multi-file projects without losing context. This capability is available now in VS Code, Copilot CLI, and the GitHub Copilot app, and is expanding to more surfaces soon.

Configurable reasoning levels

Configurable reasoning levels let you dial in the right balance of speed and depth and unlock extended thinking for your hardest architectural and debugging challenges. This capability is available in VS Code, Copilot CLI, and the GitHub Copilot app, and is expanding to more surfaces soon.

A note on AI credit consumption

Choosing a larger context window or higher reasoning level will consume more AI credits per interaction. We recommend using the default context window and reasoning level for everyday tasks, and reaching for extended context or higher reasoning when you’re tackling complex, multi-file problems.

Try it today

Select one of the supported models in VS Code, Copilot CLI or the GitHub Copilot app to try these new capabilities today. To get more information about either of these features, review our model documentation.
