Summary
GitHub made Moonshot AI's Kimi K2.7 Code generally available in the Copilot model picker — the first open-weight model, and the first from a China-based lab, to reach Copilot's roster. GitHub hosts the trillion-parameter Mixture-of-Experts model (32B active parameters per token) on Microsoft Azure, and expanded availability from Pro/Pro+/Max tiers to Business and Enterprise a week later.
Key Takeaways
- Reached GA in Copilot just 19 days after Moonshot published the weights on Hugging Face (June 12) — one of the fastest open-weight-to-enterprise-platform turnarounds on record.
- Trillion-parameter MoE architecture with only 32B active parameters per token, the sparsity that makes below-frontier pricing possible.
- Rolled out to Pro/Pro+/Max on July 1, then Business/Enterprise on July 7 — off by default for Business/Enterprise, requiring an admin policy toggle.
- Billed at provider list rates under Copilot's usage-based billing model.
