Sparse probes and murky physics: a case study of interpretability challenges in a foundation model for continuum dynamics
Researchers applied mechanistic interpretability techniques to Walrus, a foundation model for continuum dynamics, using sparse autoencoders to probe internal mechanisms. The study reveals inconsistent feature alignment with known physics and systematic discrepancies in model outputs, highlighting fundamental challenges in understanding and validating scientific AI systems.
