The work argues that representations are still largely studied along depth alone, treating each layer as a single unit rather than examining modules within layers. The finding matters for researchers who select which representations to probe when evaluating or adapting foundation models.", "body_md": "Which representation should be probed in a transformer-based foundation model?
