Deploying Kimi K3 on AWS
Moonshot AI's Kimi K3 is the first open-weight model in the 3 trillion parameter class
“Kimi K3, a 2.8 trillion parameter Mixture of Experts (MoE) model that represents the first open-weight system to reach the 3 trillion parameter class”
Moonshot AI released Kimi K3 on July 27, 2026 — a 2.8T parameter MoE model and the first open-weight system to cross the 3 trillion parameter threshold. With a 1M token context window, native multimodal support, and only 104B active parameters per token, it brings frontier-level capability to self-hosted deployments. AWS published a deployment guide covering SageMaker HyperPod and EKS, signaling serious enterprise interest in running this class of model on cloud infrastructure.
