Kimi K3.1 Pro: a 1M-context model with open weights promised by 4 November
24 October 2026
Moonshot's new model is live in the Kimi apps, Kimi Code and the API (kimi-k3.1-pro, plus a 2-3x faster Highspeed variant). Moonshot reports 65.7% on Terminal-Bench 4.0, close to the top closed models, and a much lower hallucination rate than K3. Enterprise admins must switch it on; full weights are due by 4 Nov.
Based on reporting by Moonshot AI (Kimi). Read their full coverage for details.
