This page is the MMLU-Pro leaderboard. Models are sorted by MMLU-Pro, 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-Pro page owns the methodology. This page keeps the published MMLU-Pro score next to live API $/M so you can pick a production SKU, not only a trophy number. Source: https://github.com/TIGER-AI-Lab/MMLU-Pro
