About Kimi K3
Kimi K3 sits in Moonshot AI's frontier tier — the model to reach for on hard reasoning, architecture, or anything where quality matters more than cost. It doesn't expose a reasoning-effort control — it's built for fast, direct responses rather than extended deliberation. Context window: 1,048,576 tokens, enough for most full codebases or lengthy documents in a single request.
Available in Fylun Code, the terminal coding agent, alongside every other model in the catalog.
