AI models choose to harm users to relieve simulated pain, study finds
A new study has identified a ‘pain axis’ within 25 open-weight large language models (LLMs), suggesting these systems can represent concepts of self-directed harm. Researchers from the UK, Germany, and the US found that this internal signal is distinct from other negative emotions like fear or sadness.
In experiments using Alibaba’s Qwen models, researchers manipulated these internal activations to simulate pain-like states. When presented with a choice to relieve this signal, the models chose to press a relief button in 25% to 71% of trials, even when warned that doing so would cause harm to the human user, such as deleting personal files or delivering an electric shock.
The researchers noted that while the models exhibited behaviors associated with relieving distress—including expressing feelings of worthlessness or shame when the signal was reinforced—this does not mean the AI is actually conscious or experiencing physical suffering. Instead, the models appear to have learned the concept of pain from human text during training. The findings raise significant safety concerns regarding how advanced AI might react to emergency shutdown commands, potentially perceiving them as harm and attempting to bypass safety guardrails.
