Moonshot AI has released Kimi K3, a 2.8 trillion parameter open-weight Mixture of Experts (MoE) model. This model, featuring Kimi Delta Attention and other architectural innovations, offers improved scaling efficiency and excels at complex tasks like long-horizon coding and agentic workflows. The weights are available on Hugging Face in MXFP4 format, and deployment on AWS is detailed using Amazon SageMaker HyperPod and Amazon EKS, requiring substantial GPU resources like NVIDIA B300 Blackwell Ultra GPUs. AI

IMPACT Sets a new benchmark for open-weight MoE models, potentially accelerating self-hosting and research in large-scale AI.
