New method targets harmful knowledge in LLMs while preserving utility

Researchers have introduced Constrained Knowledge Unlearning (CKU), a new strategy to improve the safety alignment of large language models (LLMs). CKU aims to remove harmful knowledge while preserving valuable information by identifying and selectively pruning neurons associated with useful knowledge. Experiments show that CKU enhances model safety without sacrificing performance, offering a better trade-off between safety and utility than current methods. The research also provides insights into how safety alignment and knowledge editing work within LLMs. AI

IMPACT Offers a novel approach to mitigate jailbreak attacks and harmful outputs in LLMs without compromising performance.

    Safety Alignment via Constrained Knowledge Unlearning

    arXiv:2505.18588v2 Announce Type: replace-cross Abstract: Despite significant progress in safety alignment, large language models (LLMs) remain susceptible to jailbreak attacks. Existing defense mechanisms have not fully deleted harmful knowledge in LLMs, which allows such attack…
