πŸ‘οΈ Top 7 Open Source OCR Models in 2025

OCR is having a renaissance. We’re no longer talking about extracting plain text with errors β€” modern models convert PDFs and complex images into precise Markdown, understanding tables, formulas, and diagrams. All runnable locally.

πŸ† The 7 models:

  • πŸ₯‡ olmOCR-2-7B β€” Allen Institute for AI. Best for equations and complex tables. 82.4 on olmOCR-bench.
  • 🌍 PaddleOCR-VL (0.9B) β€” 109 languages (including Spanish), ultra-compact. Leads OmniDocBench.
  • πŸ“„ OCRFlux-3B β€” Best for PDF β†’ Markdown. Cross-page table and paragraph fusion.
  • πŸ“± MiniCPM-V 4.5 (8B) β€” Outperforms GPT-4o and Gemini-2.0 Pro on average. Runs on mobile.
  • ⚑ InternVL 2.5-4B β€” Efficient for resource-constrained environments.
  • 🏒 Granite Vision 3.3 (2B) β€” IBM. Focus on enterprise documents, tables, and charts.
  • πŸ“ TrOCR Large β€” Microsoft. Classic Transformer for simple printed text.

πŸ’‘ Quick explanation

Traditional OCR reads text as if “photographing” individual characters. New models are multimodal: they understand context, document structure, and content semantics. The difference is like between a basic scanner and an assistant that reads and comprehends the document!
