    How often is the Aa Index leaderboard updated?

    Scores and API prices on this page are refreshed from published evals and provider rates. The snapshot is labeled August 20, 2026. Treat it as a current index, not a one-off blog post.

    What is Aa Index?

    Aa Index is a public LLM eval (the Aa Index score). This page ranks models that have published a score, next to live API prices.

    Where is the Aa Index leaderboard?

    This page is the Aa Index leaderboard. Models are sorted by Aa Index, 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 Aa Index ranking different from the official board?

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