New benchmark reveals MLLMs struggle with complex topological reasoning

Researchers have introduced ReactBench, a new benchmark designed to evaluate the topological reasoning capabilities of Multimodal Large Language Models (MLLMs) when processing complex chemical reaction diagrams. Existing benchmarks are insufficient for assessing MLLMs' ability to handle branching, converging, and cyclic structures, leading to a significant performance drop. ReactBench, featuring 1,618 expert-annotated QA pairs, reveals that MLLMs struggle with holistic structural reasoning, showing performance gaps exceeding 30% compared to simpler anchor-based tasks. This highlights a fundamental deficit in visual reasoning beyond basic perception. AI

影响 Highlights a critical gap in MLLM reasoning, potentially guiding future research towards more robust structural understanding.
