Moonshot AI
GitHub announced general availability of Kimi K3, an open-weight coding model from Moonshot AI, inside GitHub Copilot (VS Code, JetBrains, github.com) as of August 6, 2026, hosted on Fireworks AI infrastructure at $3/$15 per million input/output tokens. Rollout had been briefly paused for a GitHub Actions incident before resuming; the feature is off by default for Business/Enterprise plans pending admin policy enablement.
