Summary
Moonshot has published the full Kimi K3.1 Pro weights on Hugging Face, as it had promised for November 4. It is a mixture-of-experts model with 2.8 trillion parameters, 104 billion active per token, and MXFP4 experts. AI News Report puts the download at about 1.56 TB, so serving needs a multi-GPU server. The custom license requires a separate deal above $20 million in 12-month revenue before selling it as a service. The benchmark scores are Moonshot's own, and the file size and license wording could not be independently verified.
