Organic chemistry V2 — spectroscopy, synthesis, and structure-image problems. This page ranks models that have published a Organic Chemistry score, with live API token prices on the same row.
This page is the Organic Chemistry leaderboard. Models are sorted by Organic Chemistry, with input and output token prices on the same row so you can weigh score against cost. Official boards often omit price; that comparison is the point of this index.
Official eval pages own the methodology. This page keeps the published Organic Chemistry score next to live API $/M so you can pick a production SKU, not only a trophy number.
