Thinking in Structures: Evaluating Spatial Intelligence in Constraint-Governed Spaces
Researchers have introduced SSI-Bench, a new benchmark designed to evaluate the spatial intelligence of vision-language models (VLMs) in complex, constraint-governed environments. The benchmark features 1,000 ranking questions focused on geometric and topological reasoning within real-world 3D structures, requiring models to resolve intricate spatial relationships. Current VLMs show a significant performance gap compared to humans, with the best models achieving only 33.6% accuracy, indicating fundamental limitations in their spatial understanding. AI
