Moonshot publishes the weights of Kimi K3.1 Pro on Hugging Face, keeping its promise to release them by 4 November

Moonshot AI has made the weights of Kimi K3.1 Pro public on Hugging Face, in the repository moonshotai/Kimi-K3.1-Pro. When Moonshot launched the model through its API in late October, it promised the full weights by 4 November; that launch ran here on 24 October. What has changed is that the weights can now be downloaded and run by anyone.

The model card describes a mixture-of-experts model with 2.8 trillion parameters in total, 104 billion of them active, and a context of 1,048,576 tokens.

The licence, titled the Kimi K3.1-Pro License, uses MIT-style wording and adds conditions. A business that sells the model as a service and has more than US$20m of revenue in any 12 months must sign a separate agreement with Moonshot. Products with more than 100 million monthly users, or more than US$20m of monthly revenue, must display “Kimi K3.1-Pro”.

The Hugging Face activity feed showed the model as published on 4 November, although some files were uploaded earlier. PANews reported that Moonshot has released the open weights on Hugging Face.
