Moonshot Releases Open-Weight Model Kimi K3.1 Pro
Posted As of
Moonshot AI has uploaded the weights of Kimi K3.1 Pro, a multimodal agent model, to Hugging Face. The parameter count is listed as 2.8T (official) and the model is under a dedicated license.
What happened
- The content is based on the Moonshot AI model card on Hugging Face. Reports conflict on the release date, November 4 or 5, so the repository history needs to be checked.
- The model card describes it as an open-weight native multimodal agent model and Moonshot's top-performing model in the 3T class.
- It was post-trained with large-scale reinforcement learning on Kimi K3 and is the first model in the K3.1 series.
- The page lists 2.8T (official) parameters, and the API model ID is kimi-k3.1-pro.
- The license is not Apache or MIT but a separate "Kimi K3.1 Pro License."
Our take
The official materials include no guidance for running it on laptops or Macs, and reports say it requires a multi-GPU server. We have not found official GGUF or MLX builds, only community uploads. Active parameters, context length, and revenue terms in the license are based on secondary sources and remain unconfirmed, so the LICENSE file should be read directly before any commercial use.
