Meta's Nougat is a visual transformer for "Neural Optical Understanding for Academic documents" that converts PDFs to LaTeX/Markdown.
Academic-document focused: Specifically targets academic PDFs, where equations, tables, and reference formatting challenge general-purpose OCR systems.
End-to-end visual transformer: A single visual transformer processes PDF page images into structured Markdown/LaTeX directly - no separate OCR + layout pipeline.
Equation and table extraction: Handles mathematical equations and tables, producing LaTeX-correct output rather than flat text.
Open release: Released with weights, enabling researchers to turn academic PDF collections into machine-readable corpora for downstream training and analysis.
