Moonshot launches Kimi K3.1 Pro, with open weights due by November 4

Moonshot announced Kimi K3.1 Pro, which it calls its most capable 3T-class open-weight model: a multimodal mixture-of-experts model with 2.8T total and 104B active parameters and a 1M-token context. Moonshot says K3.1 Pro and K3.1 Pro Highspeed (2–3× faster) are live on Kimi.ai, Kimi Work, Kimi Code and the Kimi API (model ids kimi-k3.1-pro and kimi-k3.1-pro-highspeed). Open weights are promised by November 4, 2026.DeepSeek· Infrastructure
