High OCR scores can mask field mapping and structural failures that destroy table usability.
Methodology, not just scores, determined which extraction APIs would work in production.
Balancing speed, cost, and accuracy requires routing, not a single parsing model.
Two competing architectures determine which vendor succeeds on scanned PDFs.
Spatial reasoning problems favor specialist document AI over scaled general models.
Regulators demand accountability at every step of document processing, not just faster data capture.
Accuracy and engineering time, not license fees, determine which tool wins.
Most vendors stop at extraction, leaving the layers that determine production reliability unbuilt.
