Toolkit for linearizing PDFs for LLM datasets/training

+Excellent handling of complex document layouts including equations, tables, handwriting, and multi-column formats with natural reading order preservation
+Cost-effective processing at under $200 per million pages, making it economical for large-scale dataset creation
+Continuous model improvements with recent releases showing significant performance gains and reduced hallucinations on blank documents

-Requires GPU resources due to 7B parameter model, making it computationally intensive and potentially expensive to run
-May require multiple retries for some documents to achieve optimal results
-Limited to image-based document formats (PDF, PNG, JPEG) and requires technical expertise for setup and optimization

•Converting academic papers and research documents with complex equations and figures for LLM training datasets
•Processing legacy document archives with multi-column layouts and mixed content types into searchable text format
•Creating high-quality training data from technical manuals, textbooks, and scientific publications for domain-specific language models
