moonshot/kimi-k3
Kimi K3 is Moonshot AI's open-weight flagship: a 2.8T-parameter sparse-MoE model (104B active) with a 1M-token context window and native image understanding. Reasoning is always on, with three effort levels (low / high / max) selected via reasoning_effort, and thinking is streamed as separate reasoning_content deltas. Supports tool calling, JSON Schema structured output and automatic prefix caching. Available through the OpenAI-compatible and Anthropic Messages interfaces.
