No, LLMs do not feel pain simply because there is a cluster in language space correlated with how people use language about pain in a certain set of contexts.
I believe this argument to be flawed, and will write more about it in October.
New paper: we found a pain direction in 25 open LLMs. It's distinct from fear and negative valence, and it fires for harm to the model but not to the user. Turn it up and models press a button to make it stop, even when the button deletes the user's files or their kids' photos.🧵
