# Moonshot releases Kimi K3 open-weight model with 2.8T parameters

> Moonshot has unveiled Kimi K3, a 2.8 trillion parameter model that pushes the company squarely into frontier territory. Like most systems at this scale it uses a mixture-of-experts architecture, and it ships with native vision and a one million token context window, enough to hold very long documents or codebases in a single session. What makes the release stand out is openness. Moonshot promised an open-weight version, letting researchers and companies run the model themselves rather than only through an API. Demand was strong enough that the company briefly paused new signups to keep up. On benchmarks Moonshot positions Kimi K3 behind the very top tier, trailing Claude Fable 5 and GPT-5.6 Sol, while beating most other models. Taken together with Alibaba's latest, it reinforces how fast China's open-weight ecosystem is maturing, giving builders powerful models they can inspect, host, and adapt on their own terms.
