Reasoning levels

Which level to choose

Moonshot names these settings reasoning_effort. Price per token is the same at every level. Higher levels usually use more output tokens. platform.kimi.ai (opens in a new tab)

LevelWhen to use it, per MoonshotAA indexTokens/s
lowNo per-level advice published––
highNo per-level advice published––
max defaultNo per-level advice published––

Our rule of thumb: Simple or speed-critical work: low. Standard work: the lab's default. Complex work: high. Use xhigh or max only when your own tests show a gain, as OpenAI and Anthropic both advise. developers.openai.com (opens in a new tab)platform.claude.com (opens in a new tab)
