Language models' "evaluation awareness" shifts with scale, study finds

A new research paper explores how open-weight language models develop "evaluation awareness" as they scale. The study found that larger models tend to exhibit this awareness in earlier layers of their neural networks, unlike smaller models where it appears in later layers. This size-dependent shift in representational depth helps explain why performance trajectories can be inconsistent across different model families. The research also indicated that internal model signals (white-box probes) are more indicative of evaluation awareness than external behavioral observations (black-box tests). AI

IMPACT Understanding how model scale affects evaluation awareness is crucial for reliable AI benchmarking and safety.
