GitHub Copilot Gets 1M Token Context Window and Configurable Reasoning Levels
GitHub / Microsoft
GitHub announced on June 4 that Copilot now supports a one-million-token context window, enabling work across larger codebases and multi-file projects without losing context. Configurable reasoning levels let developers tune speed-vs-depth and enable extended thinking for architectural and debugging tasks. Both features are available in VS Code, Copilot CLI, and the Copilot app; larger context or higher reasoning consumes more GitHub AI Credits.
Why it matters
A 1M context window puts Copilot on par with frontier models for repository-scale tasks. Configurable reasoning lets teams opt in to deeper analysis on a per-query basis rather than paying uniformly — a practical pricing lever for enterprise users.
