Artificial Analysis 测评:Claude 升档位比拉满 effort 更划算

Artificial Analysis 对 Anthropic 当前 Claude 系列做了 Cost per Task 与 Time per Task 对比,结论是升级模型档位比在同一模型上拉满 effort 参数更能换来每美元智能。Claude Opus 5.5(xhigh,得分 57)超过 Claude Sonnet 5.5(max,得分 55),且 Cost per Task 低 40%,Time per Task 约为其一半。 进一步看,Claude Fable 5.2(high)的表现超过 Opus 5.5(max),成本和时间都有节省;Fable 5.2(low)则超过 Opus 5.5(high)。也就是说,在大模型梯队里,每一档更大的模型几乎都落在性能-成本帕累托前沿上,与其烧更多推理算力,不如直接换更大的模型。 这一规律在最低档不成立:从 Claude Haiku 5.5(max)再往上走,每一步都意味着成本上升,性价比反而下降。对开发者和企业采购来说,选型的第一杠杆是模型档位,effort 参数更适合在已定档位内做微调。

Artificial Analysis 用 Cost per Task 数据算了一笔账:Opus 5.5 开 xhigh 比 Sonnet 5.5 拉满 effort 又快又便宜,Fable 5.2 也压过 Opus。做 Claude API 选型的人该看看这份对比,别只盯着 effort 参数调。
