We argue that progress in true multimodal intelligence calls for a shift from
reactive, task-driven systems and brute-force long context towards a broader
paradigm of supersensing. We frame spatial supersensing as four stages beyond
linguistic-only understanding: semantic perception (naming what is seen),
streaming event cognition (maintaining memory across continuous experiences),
implicit 3D spatial cognition (inferring the world behind pixels), and
predictive world modeling (creating internal models that filter and organize
information). Current benchmarks largely test only the early stages, offering
narrow coverage of spatial cognition and rarely challenging models in ways that
require true world modeling. To drive progress in spatial supersensing, we
present VSI-SUPER, a two-part benchmark: VSR (long-horizon visual spatial
recall) and VSC (continual visual spatial counting). These tasks require
arbitrarily long video inputs yet are resistant to brute-force context
expansion. We then test data scaling limits by curating VSI-590K and training
Cambrian-S, achieving +30% absolute improvement on VSI-Bench without
sacrificing general capabilities. Yet performance on VSI-SUPER remains limited,
indicating that scale alone is insufficient for spatial supersensing. We
propose predictive sensing as a path forward, presenting a proof-of-concept in
which a self-supervised next-latent-frame predictor leverages surprise
(prediction error) to drive memory and event segmentation. On VSI-SUPER, this
approach substantially outperforms leading proprietary baselines, showing that
spatial supersensing requires models that not only see but also anticipate,
select, and organize experience.
