思考的代价：推理努力作为模型特定API合同条款

AI 摘要

该研究通过注册的配对对比实验，考察了Sonnet 5模型在显式高推理努力与省略该参数两种API合同下的成本与准确性差异。结果显示，显式高努力合同使每次调用成本平均增加0.01031美元，但未检测到准确性的显著差异。研究还发现，推理努力的省略语义在不同模型间甚至同一供应商内存在差异，强调了API合同条款对成本与结果的重要性。

The Price of Thinking: Reasoning Effort as a Model-Specific API Contract Abstract API buyers purchase a dated contract, not a model name alone: the contract includes the requested and served model, reasoning-effort term or its omission, output rail, service product, prompt, and price schedule. We study the reasoning-effort term through a registered paired contrast of Sonnet 5 with explicit high effort against the same model with effort omitted, using 30 AIME 2026 items and five calls per item.
