This page is the Automationbench Aa leaderboard. Models are sorted by Automationbench Aa, 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 Automationbench Aa score next to live API $/M so you can pick a production SKU, not only a trophy number.
