Kimi K2.7 Code, First Open-Weight Model in GitHub Copilot, Now Available Across All Plans

My take: Kimi K2.7 Code just became the first open-weight model available in GitHub Copilot's model picker, expanding this week to Business and Enterprise plans after going generally available for Pro, Pro+, and Max on July 1.

What sets this model apart from others in Copilot is not just its size (roughly one trillion total parameters, with 32 billion active per token) or context window (256K tokens), but access to its weights. Being open-weight means security and compliance teams can audit the model in depth, something not possible with proprietary models in Copilot. Outside Copilot, Moonshot charges $0.95 per million input tokens, which can represent real savings for teams with high code volumes. Moonshot also reports the model reduces reasoning tokens by 30% compared to earlier versions, though that figure comes from the maker, not independent tests.

For any technical lead or development team, the relevant question is: does your organization already have a clear policy on which models to choose based on the level of auditability, privacy, and cost per task?
