Kimi K3's full weights are here, but they're 'open' with a caveat: What enterprises should know

Moonshot AI has released the full weights for Kimi K3, its most performant model featuring a 2.8 trillion-parameter architecture and a one million-token context window. While the model is open, enterprises must adhere to a specific custom usage license. Following its initial API debut, the rollout now includes a 47-page technical report. The developer community is currently evaluating Kimi K3's practical coding capabilities and ecosystem as an alternative to GPT, Claude, and Gemini.
