Reasoning levels

Which level to choose

Meta names these settings reasoning_effort. max uses more reasoning tokens at the same per-token price, per Meta. dev.meta.ai (opens in a new tab)

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)
