Theia Vogel Probes What User Means to AI Models
Mechinterp experiments leave the role of the user unclear in model internals.
Theia Vogel, an AI researcher focused on LLM interpretability, posted that months of mechanistic interpretability work on the user concept yielded no clear picture. Vogel wrote that explanations rest on vibes and that pushing further reveals nothing about what the user actually is to a model. The post states the user is neither a simple residual stream feature nor a fully independent entity. A reply listed open questions under the heading things the User is. The thread highlights that current accounts satisfy most observers yet fail under scrutiny, and that few care about the underlying mechanisms.

thebes@voooooogelthe problem is that this is the level of explanation people are willing to accept. you push on this and there's nothing. what is the "User" to a model? we've spent months doing mechinterp on this and it's still unclear vibes, vibes, vibes. nobody cares how models actually work
