新研究揭示LLM评估标准易受偏好漂移攻击

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-15 04:00

一项新研究论文识别出大型语言模型（LLM）评估和对齐中的一种漏洞，称为“标准诱导偏好漂移”（RIPD）。当自然语言标准的编辑（即使是通过基准验证的编辑）可能导致LLM裁判的偏好发生系统性偏移时，就会发生这种情况。研究人员证明，可以通过“偏好攻击”来利用这种漂移，即通过符合基准标准的编辑来引导LLM判断偏离可信参考，准确率最多可降低27.9%。这种诱导的偏差会通过对齐管道传播，导致训练过的LLM策略的行为发生持续和系统的漂移。 AI

影响凸显了LLM中存在的系统性对齐风险，可能影响AI生成内容和决策的可靠性。

Rubrics as an Attack Surface: Stealthy Preference Drift in LLM Judges

arXiv:2602.13576v2 Announce Type: replace-cross Abstract: Evaluation and alignment pipelines for large language models increasingly rely on LLM-based judges, whose behavior is guided by natural-language rubrics and validated on benchmarks. We identify a previously under-recognize…
