Kimi K3 is Moonshot AI's open-weight flagship: a 2.8-trillion-parameter Mixture-of-Experts model with native vision and a 1,048,576-token context window.
Kimi K3 is designed for long-horizon coding, knowledge work, and reasoning. Each token activates 16 of its 896 experts, totaling 104B active parameters. Full details are in Moonshot's announcement.
On a Shared Endpoint, you pay per token. The endpoint is OpenAI-compatible and already live: point your existing SDK at it and start sending requests.
A Dedicated Endpoint is your own deployment of Kimi K3, on an inference stack that Modal tunes and autoscales. Bring fine-tuned weights if you have them. Compute is billed by the second, and only while it runs.
