Frequently Asked Questions
Should I use Docling or Marker for PDF-to-Markdown RAG ingestion in 2026?
Choose Docling (68.9k stars, MIT license) for permissive enterprise deployments needing 96.8% financial table structure preservation via DocLayNet and TableFormer. Choose Marker (40.5k stars) when you need maximum GPU throughput (24.0 pages/sec) and LaTeX equation extraction.
How much does local Docling or Marker save compared to managed cloud document OCR APIs?
Managed cloud document parsing APIs charge $10.00 per 1,000 pages ($2,500/mo at 250,000 pages). Running Docling or Marker on a single spot L4/A10G GPU costs $0.28 per 1,000 pages ($70/mo), reducing ingestion spend by 97.2%.
