Moonshot Launches Kimi K3.1 Pro With 1M Context
Open weights shipping on 4 Nov would make K3.1 Pro the leading open-weights model, giving teams a top-4-lab option they can self-host instead of paying API rates. The WebDev ranking also signals it is tuned for practical coding work, not just benchmarks. Builders in Southeast Asia can try it immediately via the API before deciding whether the open weights fit their stack.
Moonshot (Kimi) launched Kimi K3.1 Pro on 24 Oct as a 2.8T-parameter MoE model with 104B active parameters and a 1M-token context window. It is live now on the Kimi web app, mobile, and API, with open weights scheduled for 4 Nov 2026. The model scored 55 on the Artificial Analysis Intelligence Index, ranking 4th overall and 11 points above Kimi K3, and landed 8th on Arena's WebDev leaderboard.
