RoboStressBench - Spatial Reasoning: leaderboard
RoboStressBench (2026) tests vision-language models on embodied-scene images under physically grounded visual stress (dark, transparent or specular materials, extreme viewpoints, occlusion and clutter, over- and under-exposure). This board is accuracy in percent on its 1,369 spatial-reasoning multiple-choice questions, with greedy decoding and at most 64 new tokens; higher is better.
Metric: Accuracy (%) on the 1,369 spatial-reasoning multiple-choice questions, exact match on the predicted option, greedy decoding with at most 64 new tokens (API models: temperature 0, 64 output tokens), one unified instruction template; images of embodied scenes under physical visual stress (material, viewpoint, lighting, geometry); higher is better. Source: arxiv.org. Saturation forecast: Around February 2027. 16 models tracked.
