Kimi drops K3.1 Pro weights on Hugging Face
Kimi just released the open weights for K3.1 Pro on Hugging Face under a dedicated license. Billed as its most capable 3T-class model yet, the release packs native multimodality and agentic capabilities directly into the hands of open-source builders.
Kimi just released the model weights for K3.1 Pro on Hugging Face, officially open-sourcing the system under a dedicated "Kimi K3.1 Pro" license.
A 3T-class multimodal agent
According to the team, K3.1 Pro is an open-weight, natively multimodal agentic model and stands as their most capable 3T-class model to date.
Alongside the drop, the team reaffirmed its commitment to advancing open intelligence by putting frontier capabilities directly into builders' hands.
Why it matters
Dropping the weights of a 3T-class native multimodal agent is a welcome move for developers who want local control instead of getting locked into proprietary APIs.
We think Kimi is making a calculated play to rally the open-source community around its ecosystem. That said, because the release ships under a custom license, teams aiming for commercial deployment will need to review the fine print carefully before shipping.
