Researchers have developed DANGERLENS, a new probe designed to uncover hidden dangerous concepts within language models that may persist despite safety alignment training. By mapping internal model states to vocabulary space, DANGERLENS can differentiate between genuine hazard recognition and residual harmful knowledge. Experiments on Qwen1.5 models indicate that models with prior exposure to harmful data retain greater accessibility to these dangerous concepts, even when exhibiting similar safe output behaviors. This suggests that internal accessibility audits are crucial alongside external safety evaluations to fully understand a model's safety. AI
