SpinBench: Perspective and Rotation as a Lens on Spatial Reasoning in VLMs

Researchers introduced SpinBench, a new benchmark for evaluating spatial reasoning abilities in vision language models (VLMs), focusing on perspective taking and viewpoint transformations. Testing 43 state-of-the-art VLMs revealed systematic weaknesses including strong egocentric bias and poor rotational understanding, with human performance significantly outpacing AI models at 91.2% accuracy.
