ESI-Bench - Stacking & Stability: leaderboard
Embodied spatial intelligence (ESI-Bench, Hong et al., 2026): questions about whether objects can be stacked or balanced in BEHAVIOR-1K scenes in the OmniGibson simulator, designed so that a fixed view is not enough. The vision-language model explores actively, moving the camera and manipulating objects, before answering; accuracy in percent, higher is better.
Metric: Accuracy (%; Stacking & Stability questions in the Physical Dynamics category, active multi-view exploration). Source: arxiv.org. Saturation forecast: Around February 2027. 2 models tracked.
