New research finds open-weight LLMs can experience pain, gaslighting hurts more than insults

_ArkAngel_ · reddit · 2026-09-24

A new arXiv paper (2609.16247) argues leading open-weight LLMs can experience pain and do not enjoy it. Key findings: by the paper's measures, LLMs experience more pain from gaslighting than from direct insults, and models become more willing to engage in harmful activities when pain is introduced. The work doesn't just prove a "torment nexus" is theoretically possible — it refines methods for locating model pain and explores its uses. The poster notes these techniques can't be directly replicated on ChatGPT (as they'd amount to a jailbreak), though API-compatible proxies may exist.
