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