New research compares LLM behavior to internal semantic geometry

Researchers investigated the relationship between Large Language Models' (LLMs) internal representations and their observable behavior. By conducting over 17.5 million trials across eight instruction-tuned transformer models, they compared behavioral data from similarity-based forced-choice and free association tasks with the models' hidden-state geometries. The study found that forced-choice behavior more closely mirrored the internal states than free association, suggesting that behavioral measurements can indeed reveal information about an LLM's semantic geometry.

    From Associations to Activations: Comparing Behavioral and Hidden-State Semantic Geometry in LLMs

    arXiv:2602.00628v3 Announce Type: replace-cross Abstract: We investigate the extent to which an LLM's hidden-state geometry can be recovered from its behavior in psycholinguistic experiments. Across eight instruction-tuned transformer models, we run two experimental paradigms -- …
