What is Kimi K3?

Kimi K3 is Moonshot AI's flagship model for long-horizon coding, agent workflows, and end-to-end knowledge work. It combines a 1M-token context window with native visual understanding, giving builders room to work across large codebases, long document collections, images, and video inputs in one workflow.

  • 1M-token context window: analyze large repositories, research corpora, and extended project histories
  • Long-horizon coding: plan and execute complex programming work across many steps
  • Native multimodal understanding: work with text, images, and video input
  • Agent-ready tool use: call external functions and APIs for multi-step workflows
  • Structured output: use JSON mode for reliable downstream processing
  • Controllable reasoning: choose low, high, or auto reasoning effort for the task

Moonshot AI describes Kimi K3 as a 2.8-trillion-parameter model built for industry-leading intelligence. On Atoms, Kimi K3 can power practical product work rather than stopping at chat: research the problem, plan the build, generate the code, review the result, and ship.
