This in-depth benchmark compares DeepSeek-OCR (MIT licensed), PaddleOCR, and Tesseract. DeepSeek-OCR achieves 96-97% accuracy on OmniDocBench and uses its unique 10x text compression for millisecond inference on long documents. It is 2-3x faster than Tesseract in production and outperforms PaddleOCR on complex layouts (like tables and formulas), being named the best Deep OCR tool for 2025.
