Moonshot's Kimi K3.1 Pro pulls an open-weight model to within a point of the frontier
The 1M-token model scores 65.7% on Terminal-Bench 4.0, costs $2/$10 per million tokens, and Moonshot says the full weights ship by November 4.
Moonshot AI has released Kimi K3.1 Pro, the first model in its K3.1 series, along with a faster K3.1 Pro Highspeed variant that it says runs two to three times quicker. The company calls it its most capable 3T-class model.
