STEMVerse - Chemistry - Organic Chemistry: leaderboard

STEMVerse chemistry problems labelled with the sub-discipline 'Organic Chemistry', drawn from existing STEM benchmarks pooled into one set; labels come from GPT-4o and were checked by an expert audit. Few-shot prompting in the MegaScience style; accuracy in percent, higher is better. Li et al. (ZGCA and NTU), 2026 preprint.

Metric: Few-shot accuracy (%). Source: arxiv.org. Saturation forecast: Estimated already saturated. 16 models tracked.
