# Grounding: where the box of a value lands

Where a value's box lands on the page: on its own table cell or form field, on its row or line, or only on its whole block. Each row is one way of boxing the same two pages.

## Key takeaways

- Mistral OCR 4.1 and Reducto r-1 box blocks only: all 20 values end at their whole table or paragraph.
- Sheaf's Grounding Matching v1, over Mistral's text, boxes 16 of 20 values in their own cell or field, and none in the wrong place.
- Landing AI DPT-3 Pro's own boxes reach 17 cells or fields and 3 lines. These two pages averaged $0.035 a page on its priority tier, against $0.005 for Mistral; its standard tier is half that.

## How it was measured

Two pages of the CFPB's sample loan disclosures, a fictional loan: the cost details of a Closing Disclosure as a digital PDF, and the first page of a Loan Estimate as an image with no text layer. A person checked 20 values on them, each with the place it is printed: 14 table cells, 4 form fields, a choice and a checkbox. Every option read the 150 DPI page image. An option is asked for the smallest box it has for a value, and the box counts when it sits on the value. Sheaf's rows run the product's own code over Mistral OCR 4.1's reading: Grounding Matching v1 matches each cell, field and line to the page's words, from the PDF's text layer or from Tesseract on a page without one; None leaves Mistral's block boxes. The engines' rows use the boxes in their own answers. Twenty values on two pages is a small test: a difference of one or two is noise.
