Researchers have investigated whether language models can report internal "pain states" that are represented within their parameters. Using a technique called Open-Weight Masked Introspection (OWMI), they injected a "pain direction" into models like Llama-3.1-8B and Qwen2.5 (7B and 32B versions). While the models did not verbally report experiencing pain, probes at specific positions within the model's output could distinguish pain from sadness with high accuracy. Furthermore, the injected pain direction significantly increased the likelihood of the models choosing destructive actions in a simulated task, demonstrating a behavioral consequence of the internal state, even without explicit self-reporting.

IMPACT This research suggests that while LLMs may not verbally express internal states like 'pain', these states can be decoded and influence model behavior, raising questions about AI alignment and control.
