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.
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.
