Researchers have developed a new framework called SpaceNum to evaluate how well Vision-Language Models (VLMs) understand numerical concepts within spatial contexts. Through two bidirectional tasks, Num2Space and Space2Num, the study found that current VLMs largely fail to ground numbers in spatial meaning, often performing at random guess levels. The analysis revealed that these models rely on superficial spatial cues and struggle to create stable, coordinate-aware representations or abstract structured layouts from visual input. AI
