Moonshot · Priced per token
Kimi K3.1 Pro is the first model in the new K3.1 series and our most capable 3-trillion-parameter model to date, supporting a 1M-token context window. It delivers especially notable improvements in coding, 3D creation, financial research, and other long-horizon agent capabilities. We are also releasing Kimi K3.1 Pro Highspeed, which offers the same level of intelligence with roughly 2–3× faster output. The full model weights will be released by November 4.
