推理模式

支援的模型可透過 reasoning_effort 或相應參數調整思考強度。可用等級依模型而異，較高強度通常更慢且會使用更多計費 token。

先查看模型頁確認是否支援推理及正式等級名稱。
程式不應假設所有模型都有 low、medium、high；不支援時請省略參數。
從最低可接受強度開始，並以 usage、延遲與答案品質共同評估。

Parameter	What it does
`reasoning.effort`	Reasoning depth: `"low"` / `"medium"` / `"high"`. Lower effort — fewer reasoning tokens, cheaper responses
`reasoning.max_tokens`	Token budget for reasoning (Anthropic style). Must be lower than the request's `max_tokens`
`reasoning.enabled: false`	Turn reasoning off (where the model supports it)
`reasoning.exclude: true`	Hide the reasoning text from the response. Does not save money — the model still thinks and the tokens are billed

Model	Behavior
`anthropic/claude-sonnet-5`	Doesn't reason by default. `effort` and `max_tokens` enable thinking, `enabled: false` genuinely disables it
`anthropic/claude-fable-5`	Thinks adaptively — decides on its own how much. `reasoning.*` parameters are not supported (returns 400); control depth with `output_config: { "effort": "low" \| "medium" \| "high" }`
`openai/gpt-5.4`, `gpt-5.5`	Reason by default; `reasoning_effort` scales the depth
`x-ai/grok-4.3`	Reasons by default and generously (hundreds of tokens); `effort: "low"` cuts it down noticeably
`deepseek/deepseek-r1`, `z-ai/glm-5.x`	Always think: "disabling" only hides the text, reasoning tokens are still billed
