What Can DeepSeek OCR Do? Key Features
Vision-as-Compression Technology
DeepSeek OCR pioneers the use of vision as a long-context compression medium, achieving 10× lossless and 20× usable compression ratios. Its custom DeepEncoder combines window + global attention with 16× compression structure, optimized for optical compression rather than visual understanding. This revolutionary approach recovers 600-1000+ text tokens from just 64-100 vision tokens.
Multi-Language Support
Built-in support for multiple languages with high accuracy, including English, Chinese, Japanese and more. The vision-language model understands context across languages, maintaining accuracy even when terms are mixed (e.g., technical terms in English within Chinese documents).
Document to Markdown Conversion
Convert documents to structured Markdown with preserved layouts, tables, and formatting. This feature is perfect for content migration and documentation, handling complex elements like hierarchical headings, code blocks, and table structures that traditional OCR tools struggle with.
Formula and Chart Recognition
Specialized capabilities for parsing mathematical formulas (LaTeX), chemical equations, geometric notations, and extracting data from charts/diagrams. Achieves ~95% formula recognition accuracy, making it ideal for academic and scientific documents.
Multiple Resolution Modes
Flexible processing options including Tiny (64 tokens), Small (100 tokens), Base (256 tokens), Large (400 tokens), and Gundam mode for complex documents. Users can balance token consumption vs accuracy based on their specific needs.
Best DeepSeek OCR Use Cases & Applications
Academic Research Processing
Process 100-page PhD thesis in ~2 minutes on A100-40G GPU, extracting full text, mathematical formulas (LaTeX), chemical equations, and figure captions with ~95% formula recognition accuracy. Ideal for literature review and academic knowledge management.
Technical Documentation Migration
Convert legacy technical manuals, API documentation, and code-heavy documents to structured Markdown while preserving table structures, code blocks, and hierarchical headings. Enables seamless migration of documentation to modern formats.
Multilingual Business Processing
Process international contracts, invoices, and reports with mixed English-Chinese-Japanese text without manual language switching. Maintains context understanding across languages for accurate processing of technical terms in English within foreign language documents.
How to Use DeepSeek OCR: Step-by-Step Guide
Upload your document or image to the online tool (coming soon) or prepare your files for API processing. Supported formats include JPG, PNG, PDF, and other common document types.
Select your preferred resolution mode based on document complexity - Small mode (100 tokens) is recommended for most standard documents to balance accuracy and efficiency.
Choose output format options - either plain text extraction or structured Markdown conversion with preserved layouts and formatting.
Process the document through either the web interface, Python API, or batch processing system depending on your workflow needs.
Review and edit the output if needed. The high 97% accuracy means minimal post-processing required for most documents.
Export or integrate the results into your workflow - save as text/Markdown files, feed into knowledge bases, or use the structured output for documentation systems.

Is DeepSeek OCR Worth It? FAQ & Reviews
DeepSeek OCR uses a vision-language model (VLM) for context-aware OCR, achieving 97% accuracy vs Tesseract's ~85% on complex documents. It provides 100 tokens/page efficiency vs PaddleOCR's higher overhead. While requiring GPU (8GB+ VRAM), it offers superior context understanding and error correction capabilities.
Resolution modes balance token consumption vs accuracy: Tiny (64 tokens) for simple text, Small (100 tokens) recommended for most documents, Base (256 tokens) for complex layouts, Large (400 tokens) for high-res scans, and Gundam mode for academic papers with dense formulas/figures.
Yes, the 3B parameter model is fully open source on GitHub and Hugging Face under a permissive license. You can self-host, modify, and use commercially without fees. The online tool offers a free tier (10 conversions/day) with paid options for higher volume needs.
Minimum: 8GB VRAM GPU (RTX 3070/4060 Ti) for basic inference. Recommended: 16GB+ VRAM (RTX 4090, A100-40G) for production. Enterprise setups may use multi-GPU configurations for 200K+ pages/day throughput.
