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.
Massive Multitask Language Understanding — tests knowledge across 57 subjects including STEM, humanities, and social sciences. This page ranks models that have published a MMLU score, with live API token prices on the same row. Official methodology: MMLU (https://github.com/hendrycks/test).
This page is the MMLU leaderboard. Models are sorted by MMLU, 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.
The official MMLU page owns the methodology. This page keeps the published MMLU score next to live API $/M so you can pick a production SKU, not only a trophy number. Source: https://github.com/hendrycks/test
