Written by Docling, published under cdla-permissive-2.0, revision 2199320848bb, read 2026-10-19. Shown as written; SAVRN's own facts about this model are on its page.

This page contains models that power the PDF document converion package docling.

Layout Model

The layout model will take an image from a page and apply RT-DETR model in order to find different layout components. It currently detects the labels: Caption, Footnote, Formula, List-item, Page-footer, Page-header, Picture, Section-header, Table, Text, Title. As a reference (from the DocLayNet-paper), this is the performance of standard object detection methods on the DocLayNet dataset compared to human evaluation,

TableFormer

The tableformer model will identify the structure of the table, starting from an image of a table. It uses the predicted table regions of the layout model to identify the tables. Tableformer has SOTA table structure identification,
