Omni-InteractScope scored 1,479 human-annotated proactive interactions and found that all 12 tested Omni-LLMs answered on time for at most 40% of tool-invocation targets, and nine of twelve covered none of the 26 guidance sequences in full

Omni-InteractScope is a benchmark of 1,479 human-annotated, cross-reviewed interactions with 1,790 temporal targets across eight task groups, built to test whether Omni-LLMs watching continuous audiovisual streams can connect evidence to timely, sustained intervention. The results are uniformly unflattering: all 12 evaluated models produced an on-time first response for at most 40% of tool-invocation targets and joint timing-and-tool accuracy peaked at 32.0%; timely recall on query-free reminders never exceeded 23.0%; and nine of twelve models covered none of the 26 guidance sequences in full while the remaining three covered only one to three each. Controlled comparisons show tool-invocation scores alone do not establish event grounding, and reminder coverage depends on response history and frequency. The benchmark is new and the sample of models is broad but not exhaustive.

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.
