Moonshot launches Kimi K3.1 Pro, a 1M-context open-weight MoE, with weights due by Nov 4
Launched Oct 23, the 2.8T-total/104B-active multimodal model is live on Kimi.ai, Kimi Code, and the API (kimi-k3.1-pro), plus a Highspeed variant that runs 2–3x faster at about 2x the Kimi Code quota. In Kimi Code it needs a Plus plan (256K context) or Pro for the full 1M, and thinking can't be turned off (Kimi Code models).
