Vision-language models usually wait to be asked, so a streaming benchmark with 85K training samples and 4.1K evaluation samples measures whether they can act on intent nobody stated

StreamVibe targets implicit user intent, where the question is not even phrased, such as where a person should click next while navigating a website. The benchmark spans explicit, implicit and dynamic intents, and the accompanying model infers intent from a continuous observation stream and updates as it changes, backed by a harness that keeps intents as persistent states with flexible lifecycles. The reported gains are modest and specific: 10.7 percent better response timing and answer quality over existing baselines, with no degradation in general video understanding. The authors are candid that existing proactive models struggle to decide when to speak at all under implicit and dynamic intents.

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.
