Moonshot AI announced Kimi K3.1 Pro, a three-trillion-class model post-trained from K3, and Highspeed, which it says produces output two to three times faster. It offers a one-million-token context window and claimed improvements in coding, 3D creation and financial research through web, app, coding and API channels. Benchmark gains and reduced hallucinations reflect the company’s evaluation conditions. Full weights are scheduled for release by November 4, not already available for download; the Highspeed option also consumes more Kimi Code quota than the regular model.
