New research reveals distinct internal structure for harmfulness in LLMs

Researchers have identified a distinct and compact set of weights within large language models (LLMs) responsible for generating harmful content. This internal structure for harmfulness is shared across different types of harm and is separate from the model's ability to recognize or explain such content. Alignment training appears to compress these harmfulness weights, which explains why fine-tuning in one domain can lead to broad emergent misalignment, a phenomenon that can be mitigated by pruning these specific weights.

    Large Language Models Generate Harmful Responses Using a Distinct Mechanism, Shared Across Harm Types

    arXiv:2604.09544v2 Announce Type: replace-cross Abstract: Large language models (LLMs) undergo alignment training to avoid harmful behaviors, yet the resulting safeguards remain brittle: jailbreaks routinely bypass them, and fine-tuning on narrow domains can induce ``emergent mis…
