Moonshot AI released its Kimi-K3 model on Hugging Face on July 27, the company announced. The model is described as the world's first open 3T-class model designed for frontier intelligence across long-horizon coding, knowledge work, and reasoning.

The architecture is built on Kimi Delta Attention and Attention Residuals. It features native agentic capabilities including tool calling, browsing, and multi-step planning. An extended context window is designed for repository-scale code understanding.

The open weights were released on the model's Hugging Face page. The page had accumulated 1,935 users waiting for the release before the weights became public.
