The full picture
Moonshot AI's Kimi K3 model is available on Amazon Bedrock, supporting coding, document analysis, and agent workflows with Bedrock's access, encryption, and auditing controls, including explicit prompt caching. Separately, US inference providers Modal, Fireworks, and Baseten can serve Kimi K3 at one-tenth the cost of Chinese competitors because they have access to advanced Nvidia and AMD chips. Once the model is optimized for next-generation hardware such as Nvidia's Rubin architecture, operating costs could fall by 10 to 100 times.
