SpatialBrain: Spatial Intelligence Growing from Experience
SpatialBrain beat direct answers from the same fixed model on four spatial-reasoning benchmarks and tied on a fifth.
The framework retains experience about when to observe, reconstruct, measure or change reference frames without updating its vision-language backbone. It separates current-scene evidence from reusable reasoning experience, combining spatial memory, a library of tool procedures and guidance on when to use them. Completed task trajectories become process records consolidated between task blocks. Later decisions can use those records without carrying over scene coordinates or reference answers.
