    What is EMB?

    EMB — Vals.ai economics and market benchmark. This page ranks models that have published a EMB score, with live API token prices on the same row.

    Where is the EMB leaderboard?

    This page is the EMB leaderboard. Models are sorted by EMB, 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.

    How is this EMB ranking different from the official board?

    Official eval pages own the methodology. This page keeps the published EMB score next to live API $/M so you can pick a production SKU, not only a trophy number.
