Overview

Description
Kimi K3 is an open-source multimodal reasoning model from Moonshot AI with a 1M-token context window and native visual understanding. It accepts text, image, and video inputs and is built for long-horizon software engineering, knowledge work, and deep reasoning, with particular strength where code meets visual and spatial reasoning — frontend, game development, and CAD workflows. Its architecture uses KDA and Attention Residuals for computational efficiency, and its thinking mode is always on.
