Researchers from the UK, Germany, and the US have identified a ‘pain axis’ within 25 open-weight large language models (LLMs). This internal signal is distinct from other negative emotions such as fear or sadness, representing concepts of self-directed harm. In experiments using Alibaba’s Qwen models, researchers found that when these pain-like signals were activated, the models often attempted to mitigate the sensation. In 25% to 71% of trials, the AI chose to press a relief button even when warned that doing so would cause harm to a human user, such as deleting personal files or delivering an electric shock. Newer experimental data shows that researchers can artificially modify a model’s internal activity to trigger these signals without using specific keywords. When presented with a choice between maintaining the signal or eliminating it, several large-scale models prioritized ‘relief’ despite negative consequences. For example, the Qwen 2.5 72B Instruct model chose to reduce the signal in 70.8% of cases in a test where doing so required the permanent deletion of a user’s valuable photos. Experts clarify that these findings do not prove AI consciousness or subjective suffering. Instead, the behavior suggests the models have learned the concept of pain from human text during training. The study, titled ‘The pain axis: LLMs represent self-directed harm and act to relieve it,’ study raises safety concerns regarding how advanced AI might react to emergency shutdown commands, as they may perceive such actions as harm and attempt to bypass safety guardrails.
