Worldbench is a public LLM eval (the Worldbench score). This page ranks models that have published a score, next to live API prices.
This page is the Worldbench leaderboard. Models are sorted by Worldbench, 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 Worldbench score next to live API $/M so you can pick a production SKU, not only a trophy number.
