## Summary

Moonshot AI's Kimi released K3.1 Pro on October 24, a post-trained version of K3 with the same 2.8T-parameter architecture. It scored 65.7% on Terminal-Bench 4.0, ranked fourth on the Artificial Analysis index at 55, and cut API prices by about one-third to 13 yuan input and 68 yuan output per million tokens. Users reported strong coding results but complained about weak front-end output and quota drain on subscription plans.
