Ai2 Releases olmOCR 2, Turning PDFs Into Markdown at 82.4 on Bench

The Allen Institute for Artificial Intelligence (Ai2) has released an open-source OCR toolkit, olmOCR, that converts PDFs and scanned images into structure-preserving Markdown, and its latest version, olmOCR 2, scored 82.4 on the project's own benchmark after reinforcement-learning tuning. The aim is to make the vast knowledge locked in PDFs—papers, contracts, financial reports, historical archives—readable by LLMs and RAG systems.
