The company is also developing its flagship multimodal reasoning model, Kimi K3. The model features a 2.8-trillion-parameter sparse Mixture-of-Experts network. It supports text, image, and video inputs with a 1,048,576-token context window. Moonshot AI released the model as a hosted service on July 16, 2026, and published its open weights on July 27, 2026. Kimi K3 is positioned as an open-weight model that closes a significant gap to closed frontier systems on standard coding and reasoning suites. The model includes an always-on thinking mode. The administration announced that the model is available across four surfaces: the Kimi.ai chat app, the Kimi Work productivity tool, the Kimi Code terminal-based coding environment, and the Kimi API.
