Moonshot AI released full weights for Kimi K3, its 2.8-trillion-parameter multimodal Mixture-of-Experts model with a one-million-token context window, plus a technical report and support for stacks such as vLLM and SGLang. VentureBeat notes the custom license lets many developers download and deploy the model, but companies running Model-as-a-Service above $20 million in annual affiliate revenue must negotiate a separate commercial deal. Large consumer-scale products may also need prominent Kimi K3 attribution. Why it matters: China put another near-frontier open-weight giant on the table for self-hosters. Caveat: open weights are not permissive open source, and the roughly 1.5 TB package still demands serious hardware.
