Thinking in Structures: Evaluating Spatial Intelligence through Reasoning on Constrained Manifolds
ICML 2026poster
Spatial intelligence is crucial for vision--language models (VLMs) in the physical world, yet many benchmarks evaluate largely unconstrained scenes where models can exploit 2D shortcuts. We introduce SSI-Bench, a VQA benchmark for spatial reasoning on constrained manifolds, built from complex real-w…
