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