Moonshot's official Hugging Face listing now includes Kimi K3.1 Pro. On November 5, we verified a public, ungated repository containing 96 safetensors weight shards, configuration and a model card. No weights were downloaded or inference run.

What the card specifies

Moonshot lists 2.8T total parameters, 104B activated per token, text/image input and a 1,048,576-token context. The released format uses quantization-aware MXFP4 weights and MXFP8 activations. These are the publisher’s specifications, not a new independent evaluation.

A custom license

The custom license permits use and modification subject to conditions. If a licensee or affiliate operates Model-as-a-Service and their combined revenue exceeds $20 million over 12 consecutive months, a separate agreement is required before commercial use. Large-product name-display conditions and defined exceptions also apply. Read the exact license for its definitions and scope.

Publication timing remains bounded

The launch post promised weights by November 4. Hugging Face records repository creation on November 2, which does not show when it became public. We confirm availability at this check without asserting an exact release day or deadline compliance. A separate Highspeed checkpoint was not verified.
