大型语言模型安全基准可能因多选题格式而高估模型安全性

一篇新发表在arXiv上的研究调查了大型语言模型(LLMs)安全基准中的多选题(MCQ)格式为何会导致较低的拒绝率。研究人员Stepan Epifantsev及其同事使用武器级大规模杀伤性武器代理(WMDP)数据集,在Llama-3.1-8B和Qwen3-8B模型上提供了机制证据。他们的发现表明,与开放式格式中逐渐建立的拒绝过程不同,多选题会促使模型快速确定一个答案字母标记。这种多选题格式似乎与拒绝机制竞争,表明多选题安全分数可能主要反映知识而非真实的拒绝行为。 AI

影响 表明当前的大型语言模型安全基准可能无法准确评估拒绝能力,可能高估了模型安全性。

    强制一封信会抑制拒绝:来自WMDP的机制证据

    arXiv:2611.08639v1 Announce Type: new Abstract: Safety benchmarks for large language models (LLMs) commonly use multiple-choice question (MCQ) format. However, prior studies documented that MCQ format reduces refusal rates, which may significantly affect the safety behavior of th…
