Moonshot AI releases Kimi K3.1 Pro and K3.1 Pro Highspeed models

Today, we are officially launching Kimi K3.1 Pro, the first model in the K3.1 series and our most capable 3-trillion-parameter model to date, supporting a 1-million-token context. Kimi K3.1 Pro shows particularly significant improvements in coding, 3D creation, financial research, and other long-horizon Agent capabilities. We are also launching a high-speed version, Kimi K3.1 Pro Highspeed, offering the same intelligence with roughly 23x faster output. Starting today, Kimi K3.1 Pro and Kimi K3.1 Pro Highspeed are available via kimi.com, the Kimi App, Kimi Work, Kimi Code, and the Kimi API. Full model weights will be released by November 4.
