ReactBench (Reaction Diagrams) - Extraction: leaderboard

Metric: Answer accuracy (%) on the topological information extraction questions (reaction conditions, yields and labels tied to graph elements), over the 1,618 expert-annotated question-answer pairs on more than 1,300 real chemical reaction diagrams from chemistry journals and patents of ReactBench (single-line, multi-line, tree and graph topologies), multiple-choice or short open answers matched exactly against the key after template extraction, no LLM judge; higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 24 models tracked.
