Kimi (Moonshot AI)

Uses SSE streaming with OpenAI-compatible tool-calling format. Supports vision (base64 images) and reasoning content — everything from k2.5 onward is natively multimodal, no -vision variant needed. Best for: Agentic workflows, long-context tasks (K3 runs a 1M-token window), reasoning-heavy workloads, and cost-efficient daily automations.

Models

​
Reasoning modes

The brain icon next to the message box controls how this model reasons. Click it to cycle through the modes the selected model supports. Two separate ideas combine here:

​
Thinking — whether the model reasons

  • Off — the model answers immediately. Fastest and cheapest; ideal for simple, direct tasks.
  • On — the model first works through the problem in a dedicated reasoning pass before replying. Slower and uses more tokens, but markedly more accurate on multi-step, logical, or ambiguous tasks.

​
Effort — how hard it thinks

Only effort-capable models expose this; it applies once thinking is on.
  • High — standard reasoning depth. The right default for most agentic work.
  • Max — the model reasons longer and deeper for the hardest problems. More tokens and latency in exchange for higher quality on complex work.

​
Button states

Each model shows only the states it genuinely supports. If a model always reasons (can’t be turned off) or has no effort control, the button reflects that and locks where there’s nothing to change. Wolffish remembers your choice per model. On Kimi: K3 is effort-capable — Off / High / Max, driven by Moonshot’s reasoning_effort dial, and Off genuinely disables thinking (verified against the live API; Moonshot currently ships one real effort level, so High and Max behave alike until lower efforts land). k2.x models are On / Off. The k2.x-code variants reason always-on (locked on). The older moonshot-v1 models don’t reason.
Kimi K3 is Moonshot’s frontier flagship, priced alongside the premium Western mid-tier (3.00/3.00 / 15.00) with a 1M-token window. The k2.x line beneath it keeps Kimi’s classic position — between the budget Chinese providers (DeepSeek, MiMo) and the premium Western providers (Anthropic, OpenAI) — offering strong reasoning at a mid-range cost. See Choosing a Provider for guidance on when to use which tier.
