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