Moonshot Open-Sources Kimi K3
Moonshot AI introduced Kimi K3, billed as the first open 3-trillion-class model, with weights due July 27.
Scale and architecture: A 2.8T-parameter Stable LatentMoE activating 16 of 896 experts, with a 1M-token context window and native vision in a single model.
New attention design: Kimi Delta Attention delivers up to 6.3x faster decoding in million-token contexts, and Attention Residuals add roughly 25% higher training efficiency at under 2% extra compute.
Agentic strength: Leads Terminal-Bench 2.1 and scores 67.3 on DeepSWE, with demos of autonomous kernel optimization, compiler development, and vision-in-the-loop coding.
Availability: Live via Kimi.com, Kimi Code, and API from about 0.30 dollars to 15 dollars per million tokens, with open weights following on July 27.
