Prices from bench/prices.json (as of 2026-09-12); edit it for your provider — the benchmark never calls a paid API. The PDF column is the PDF pipeline that scored best in the accuracy run. Scaling: figures are measured at 1,000 documents and 1,000,000 queries; anything at other volumes (10,000 documents, 10M queries) is a linear estimate, not a measurement — index and re-index costs scale with documents, query cost scales with questions asked. Re-index: JDF re-embeds only chunks whose content hash changed (jdf embed --incremental); a PDF has no chunk identity, so an edit means re-chunking and re-embedding the whole document.
