Chain-of-Thought Reasoning Impairs Spatial Intelligence in Multimodal AI Models

ai-technology · 2026-04-20

An extensive assessment of seventeen multimodal reasoning models tested against thirteen spatial benchmarks indicates that Chain-of-Thought prompting consistently undermines performance in visual spatial reasoning challenges. Although CoT-based methodologies have revolutionized mathematical and logical problem-solving, they falter in generalized spatial intelligence. A new No-Image++ ablation study revealed that MRMs and CoT-prompted MLMs experience significant shortcut learning, often fabricating visual elements from text even in the absence of images. These results question the effectiveness of text-only CoT for spatial tasks and highlight the necessity for vision-centered reasoning frameworks. Published on arXiv, this research exposes a significant shortcoming in existing multimodal AI strategies for spatial reasoning.
