    What is Beam 128k?

    Beam 128k is a public LLM eval (the Beam 128k score). This page ranks models that have published a score, next to live API prices.

    Where is the Beam 128k leaderboard?

    This page is the Beam 128k leaderboard. Models are sorted by Beam 128k, 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 Beam 128k ranking different from the official board?

    Official eval pages own the methodology. This page keeps the published Beam 128k score next to live API $/M so you can pick a production SKU, not only a trophy number.
