Moonshot AI is making the weights for its Kimi K3 model available for public download today. The Chinese firm first launched the model on July 16 as a 2.8 trillion parameter system with a one million token context window and native vision support. It ranks close to leading US models from OpenAI and Anthropic on several benchmarks while using a sparse mixture-of-experts design that activates only a small share of parameters per token. Open weights mean anyone with enough computing power can run the model on their own hardware and change it as needed. No token fees apply once it is downloaded. The model is large enough that most users will need enterprise-level servers rather than ordinary laptops. The release follows debate in Silicon Valley over Chinese open models. Some US labs have called for tighter limits, while more than fifty tech firms signed a letter urging against early restrictions. Moonshot had already paused new sign-ups after demand hit its GPU limits.
