01kimi k3.1 pro: overview
What happened
Early on 24 October (Beijing time) Moonshot released Kimi K3.1 Pro, the first K3.1 model and what it calls its strongest 3T-parameter-class model yet, with a 1M-token context and a Highspeed variant about 2–3x faster. It is live on the Kimi web app, mobile app, Kimi Work, Kimi Code and the API, with full weights due by 4 November. Moonshot reports 65.7% on Terminal-Bench 4.0, above GPT-6 Astra's 58.2% and just below Claude Opus 5.5's 66.4%. API pricing is ¥13 per million input tokens (¥1.3 on cache hits) and ¥68 per million output tokens, doubled for Highspeed. Moonshot also says it stripped cyber-offence data from training for the open-weight release.
Why it matters
Artificial Analysis scored it 55, fourth on its Intelligence Index behind only the max settings of Opus 5.5, Sonnet 5.5 and Muse Wonder Full, and Wccftech called it the strongest model out of China, narrowing the gap between open weights and the closed frontier. VentureBeat, however, reported allegations that influencers were asked to promote it without disclosing a commercial relationship, and users complained quotas ran out fast.
Who it affects
Developers wanting cheaper coding agents, enterprises self-hosting open models, and rival model makers.
