Cursor adds Moonshot Kimi K3 with US-hosted inference
Cursor says Moonshot AI’s Kimi K3 is now available in its IDE and scores close to the frontier on CursorBench. The model is served via US-based partners Fireworks, Together, and Baseten with Zero Data Retention options for developers.
Key takeaway
A leading coding IDE is treating a Chinese open-weight model as production-ready while routing inference through US hosts and retention controls, which matters more for enterprise adoption than the original download release alone.
Context
Moonshot’s Kimi K3 had already been framed as a public-download release; Cursor’s announcement moves it into day-to-day developer workflows where model choice, latency, and data-handling policies decide real usage. Near-frontier CursorBench results are the product claim supporting that shift.
Serving through Fireworks, Together, and Baseten with Zero Data Retention is the practical bridge for Western teams that want K3 quality without sending traffic to non-US endpoints. That packaging turns a model drop into a usable alternative beside dominant US coding models.
