Kimi K2.7-Code Becomes the First Open-Weight Model in GitHub Copilot
Moonshot AI
Kimi K2.7-Code, an open-weight model from Moonshot AI with +21.8% on Kimi Code Bench v2 over its predecessor, became generally available in GitHub Copilot on July 1 — the first open-weight model selectable from the Copilot model picker. Available across VS Code (v1.127.0+), GitHub.com, JetBrains, Xcode, Eclipse, and GitHub Mobile, hosted by GitHub on Microsoft Azure.
Why it matters
Adding an open-weight option to the Copilot picker breaks the all-proprietary-model pattern and gives developers a lower-cost, auditable alternative inside their existing workflow without switching tools.
