SOMA asked 37 multimodal models to read a wearer's own body from egocentric video, and the best one reached 50.0 percent where humans reached 68.5

SOMA measures whether multimodal models can read the wearer's own body out of egocentric video, where the body is only partly visible and motion has to be inferred from occluded and temporally scattered cues, using 1,632 human-verified questions across body configuration, motion dynamics and temporal reasoning. Across 37 models the strongest, Qwen3.6-27B, reaches 50.0 percent zero-shot while human observers reach 68.5 percent, with errors concentrating on misreading the wearer's own body, misjudging events in time and a bias toward the right hand and under-counting repetitions. The benchmark, training data and code are stated as forthcoming rather than released, so the numbers are the paper's own evaluation and not yet independently reproducible.

Two sparse-autoencoder analyses have resisted scaling: matching semantically similar features across layers, and compressing large feature circuits into interpretable supernodes. This paper argues both are the same underlying problem, estimating semantic distances between SAE features that sit on different activation manifolds. Its representation treats each feature not as a single decoder vector but as an activation-weighted distribution over the hidden states expressing it, projects those distributions into a shared reference space, and compares them with Wasserstein distance. The representation is proved invariant to activation rescaling and stable under perturbation, and recovers true matches under finite-sample margin conditions. Empirically it outperformed decoder-vector and LLM-based baselines and captured subtle functional distinctions between related features, and it compressed large feature circuits into interpretable supernodes automatically. The limitation is that this is interpretability tooling: the paper demonstrates better feature matching and circuit compression, not that downstream interpretability claims become more accurate.
