Scores and API prices on this page are refreshed from published evals and provider rates. The snapshot is labeled August 20, 2026. Treat it as a current index, not a one-off blog post.
Frontier Science Research — tests ability to reason about cutting-edge scientific papers. This page ranks models that have published a Frontier Science Research score, with live API token prices on the same row.
This page is the Frontier Science Research leaderboard. Models are sorted by Frontier Science Research, 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 Frontier Science Research score next to live API $/M so you can pick a production SKU, not only a trophy number.
