The models' case: Best overall fit for highly regulated, high-volume operations: strong handwriting and messy-scan processing, human-in-the-loop exception handling, deterministic workflow. The models' main caveat: Expensive, heavyweight enterprise implementation. The strongest alternative is ABBYY Vantage — Near-tie with Hyperscience; exceptional mature OCR/ICR, broad language and document coverage, reusable document skills, REST integration, and explicit.
