    What is Ai2d?

    Ai2d is a public LLM eval (the Ai2d score). This page ranks models that have published a score, next to live API prices.

    Where is the Ai2d leaderboard?

    This page is the Ai2d leaderboard. Models are sorted by Ai2d, 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 Ai2d ranking different from the official board?

    Official eval pages own the methodology. This page keeps the published Ai2d score next to live API $/M so you can pick a production SKU, not only a trophy number.
