Kimi K3.1 Pro Highspeed does not have a researched profile yet. Everything here comes from its recorded changes and public listings, each linked to its source.
The extended-stable release gives moonshot/kimi-k3.1-pro, kimi/k3.1-pro and their Highspeed variants the K3 thinking, effort and video controls. K3.1 rejects off locally instead of returning a provider 400.
Moonshot released Kimi K3.1 Pro, a post-trained version of Kimi K3 with a 1-million-token context window, plus a Highspeed variant with 2-3x the speed. Both are available on Kimi.com, Kimi Work, Kimi Code and the Kimi API, and full open weights are due by Nov 4, 2026.
