Ever wondered which LLM-powered OCR tool reigns supreme for PDF-to-text conversion? I put three top contenders to the test in a head-to-head battle:

-Mistral OCR – A budget-friendly newcomer boasting lightning-fast markdown conversion.

-olmOCR – Allen Institute’s open-source challenger with tons of customization.

-Enhanced Gemini 2.0 Flash – Google’s powerhouse.

I threw them at some of the toughest PDFs I could find, including:

-Complex two-column layouts

-Low-quality, faded scans

-Brutal tables

-Math equations that would make Einstein sweat

Extracting structured data from PDFs, especially complex tables, is a tough challenge. We compared olmOCR, an open-source, budget-friendly tool, with Gemini 2.0 Flash, Google’s AI-powered model, to assess their performance on tricky document layouts. olmOCR is cost-effective but struggles with table accuracy, while Gemini 2.0 delivers near-perfect extraction at a higher price.
