OfficeQA โ evaluates question answering on office document understanding. This page ranks models that have published a OfficeQA score, with live API token prices on the same row.
This page is the OfficeQA leaderboard. Models are sorted by OfficeQA, 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 OfficeQA score next to live API $/M so you can pick a production SKU, not only a trophy number.
