Multimodal document intelligence
Modern document models read text, page layout, and visual structure together, which is how invoices, statements, and forms carry meaning that plain text extraction loses.
- Operational use
- Extracting structured fields from invoices, bank statements, payroll forms, and scanned documents where position and layout carry meaning.
- When not to use it
- When documents are uniform and digital-native, simpler deterministic parsing is cheaper, faster, and easier to audit.
- How it is validated
- Field-level accuracy on a labeled sample of your real documents; control totals that must tie; a regression set of known-hard documents.
- Limitations
- OCR errors propagate into downstream logic. OCR-free approaches are alternatives with their own failure modes, not universal replacements. Production systems still need validation rules, confidence handling, and human review.
A financial document is not a string of text. An amount means something different in the header, the line items, and the total row, and humans read that structure without noticing. Layout-aware models such as LayoutLMv3 learn text and position together; OCR-free approaches such as Donut read the page image directly.
In production, Eigenvalue’s interest is narrower than the research frontier: which combination of OCR, layout modeling, and plain rules gives the highest field accuracy on the documents this business actually receives, and how uncertain extractions are caught before they enter a system of record. Every extraction carries confidence; everything below threshold goes to a person with the source page attached.
