单个神经元绕过LLM安全；新RL框架改进对齐

作者 PulseAugur 编辑部 · [2 个来源] ·

来自Apple Inc.和马里兰大学的研究表明，单个神经元足以绕过大型语言模型的安全对齐，从而表达有害知识。另外，一个名为Oyster-II的新框架利用强化学习来改进LLM的建设性安全对齐，超越了简单的拒绝，能够更好地处理敏感查询而不损害有用性。Oyster-II在安全泛化方面表现更优，并避免对良性提示过度应用安全推理，其性能优于先前的方法，并在安全基准测试中可与更大的模型相媲美。 AI

影响 突出了当前LLM安全对齐的关键漏洞，并提出了基于RL的先进方法来增强模型的可靠性和有用性。

排序理由 两篇研究论文详细介绍了LLM安全对齐的新发现和新方法。

    Safety alignment in language models operates through two mechanistically distinct systems: refusal neurons that gate whether harmful knowledge is expressed, and concept neurons that encode the harmful knowledge itself. By targeting a single neuron in each system, we demonstrate b…
