MindTopo reveals VLMs’ spatial reasoning abilities
The benchmark measures both reasoning and planning, testing not only whether models can recognize topological relationships in static images but also whether they can preserve and manipulate those relationships through a sequence of actions. Current multimodal models perform much better on static recognition than interactive tasks, suggesting they struggle to maintain a consistent understanding of topology over time. Failures often emerge during planning rather than perception, with models losing track of structural relationships as scenes change or proposing actions that violate physical constraints.
