Moonshot AI Language
Kimi-K3
Open frontier multimodal MoE for long-horizon coding and agents with a 1M-token context window
About
Kimi K3 is Moonshot AI's most capable open-weight model and the largest released to date, a 2.8T-parameter Mixture-of-Experts that activates 16 of 896 experts per token for 104B active parameters. A new architecture built on Kimi Delta Attention and Attention Residuals delivers roughly 2.5x the scaling efficiency of Kimi K2 while holding a 1M-token context window with native text, image, and video understanding.
