English(EN) API-TAIL: Detecting Model Substitution in LLM APIs through Temperature-Aligned Likelihood Tails

新的API-TAIL方法检测大型语言模型模型替换

研究人员开发了一种名为API-TAIL的新方法,用于检测商业语言模型API在收取高级模型费用时秘密替换为更便宜的模型。该技术通过分析响应的“似然尾部”来工作,识别偏离由温度缩放等合法因素引起的预期变化的异常个体输出。API-TAIL旨在控制诚实提供商的误报,并在最小查询预算下有效检测低速率的替换,优于现有审计方法。 AI

影响 通过检测未披露的模型替换,该方法可以提高商业大型语言模型API服务的透明度和信任度。

    API-TAIL:通过温度对齐的似然尾部检测大型语言模型API中的模型替换

    arXiv:2610.36801v1 Announce Type: cross Abstract: Commercial language model APIs return only text, allowing a provider to cut costs by quietly routing a fraction of user requests to a cheaper substitute model while billing for the advertised one. Detecting such partial substituti…
