📖 Paper: aclanthology.org/2026.findin… ✨Current multimodal LLMs don’t truly see math diagrams -- they approximate. We introduce SpatialMath, which bridges perception and reasoning, enabling more reliable visual mathematical problem-solving.

SpatialMath: Spatial Comprehension-Infused Symbolic Reasoning for Mathematical Problem-Solving

📊 Key Findings: - Reasoning fails before retrieval - Multilingual gap is real - Effective context <30%: LLMs utilize only a fraction of their claimed context window - RAG helps, but not enough - Uncertainty reasoning is hardest
