Kimi K3 weights are open now.
It is the largest open-weight model so far (2.8T parameters). It's only slightly behind Claude Fable 5 Max and GPT-5.6 Sol Max.
Pretty excited about this model, and again, a Muon victory!

Releasing the model weights and technical report of Kimi K3.
Kimi K3 is our most capable model: a 2.8T MoE model with native visual understanding and a 1M-token context window.
New model architecture: 2.5x the intelligence per unit of compute, not just more params.
Alongside Kimi K3, we're opening up more of the stack behind it — high-performance attention kernels, MoE communication library, and infrastructure for running agent environments at scale.
