研究人员开发了 kNNGuard，这是一种无需训练或微调即可为大型语言模型 (LLM) 创建护栏的新颖方法。该方法利用现有 LLM 的隐藏激活来对提示进行安全或不安全的分类。kNNGuard 在不同领域均取得了与微调模型相当或更优的性能，同时还展现出显著更快的推理速度和快速的领域适应能力。 AI

影响这种无需训练的方法可以显著降低部署安全 LLM 的成本和复杂性，从而能够更快地集成到敏感应用程序中。

排序理由该集群描述了一篇详细介绍 LLM 护栏新颖方法的最新研究论文。[lever_c_demoted from research: ic=1 ai=1.0]

kNNGuard: Turning LLM Hidden Activations into a Training-Free Configurable Guardrail

Large language models (LLMs) are increasingly deployed in domains requiring guardrails to detect unsafe, off-topic, or adversarial prompts. Existing guardrails predominately rely on fine-tuning to build classifiers, which often suffer from low generalization and high inference la…
