What Kimi K3 is
Kimi K3 is Moonshot AI's flagship model, released July 16, 2026. It carries 2.8 trillion total parameters (104B active) in a mixture-of-experts design, is natively multimodal, and supports a 1M-token context window, positioned for long-horizon coding, knowledge work, and deep reasoning. It supersedes Kimi K2.6 (April 20, 2026) as the general-purpose flagship, with the coding-focused Kimi K2.7 Code released in June 2026. K3's weights were published on July 27, 2026 under the custom Kimi K3 License, making it one of the largest open-weights models released. K3 powers the Kimi app, Chrome extension, and desktop client, and underpins product surfaces including Agent Swarm, Parallel Agent, Website, Document, Slides, Excel, Deep Research, Kimi Claw, and Kimi Code. Moonshot AI describes the platform as 'seeking the optimal conversion from energy to intelligence' and publishes research openly alongside the product.
