The Price Reversal Phenomenon: When Cheaper Reasoning Models Cost More 事件

The Price Reversal Phenomenon: When Cheaper Reasoning Models Cost More arXiv:2603.23971v2 Announce Type: replace Abstract: Developers and consumers increasingly choose reasoning models (RMs) based on their listed API prices. However, how accurately do these prices reflect actual inference costs? We conduct the first systematic study of this question, evaluating 8 frontier RMs across 12 diverse tasks covering competition math, science QA, code generation, and multi-domain agents. We uncover the
