How to Install and Use DeepSeek-OCR: A Visual Text Compression Model Explained
How to Install and Use DeepSeek-OCR: A Visual Text Compression Model Explained
1. Introduction
DeepSeek has done it again.
On October 20, 2025, the company released DeepSeek-OCR, a brand-new open-source model for Optical Character Recognition (OCR).
Unlike traditional OCR systems that read characters sequentially, DeepSeek-OCR actually looks at them.
It introduces a visual token compression mechanism — compressing a 1,000-character document into just 100 visual tokens while maintaining up to 97% accuracy.
An NVIDIA A100 can process 200,000 pages per day, making this model ideal for document digitization, archiving, and AI-based knowledge extraction.
This guide walks you through installation, local usage, and cloud deployment on Hugging Face Spaces.
2. What Is DeepSeek-OCR?
DeepSeek-OCR is a vision-based text extraction model for scanned documents, PDFs, and complex layouts.
Instead of character-level recognition, it uses visual tokenization to process entire pages at once for faster and more accurate inference.
Parameter | Description |
---|---|
Model Size | 3 B (3 billion parameters) |
Input | Images / PDF snapshots |
Output | Plain text or JSON |
Context Length | Up to 8 K tokens |
Frameworks | PyTorch / Transformers |
Repository | Hugging Face – DeepSeek-OCR |
Recommended GPU | RTX 3090 / A100 (≥ 16 GB VRAM) |
3. Key Highlights
- Visual Token Compression – Processes entire pages as image tokens.
- Compact 3B Parameters – Lightweight yet high-accuracy.
- Complex Layout Recognition – Handles multi-column text, tables, headers, footnotes.
- Local Deployment Support – Run fully offline; ideal for confidential data.
- Multilingual – English, Chinese, Japanese, Korean supported.
4. Installation and Environment Setup
Step 1 – Create Environment
conda create -n deepseek_ocr python=3.10
conda activate deepseek_ocr
Step 2 – Install Dependencies
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
pip install transformers accelerate pillow tqdm
Step 3 – Download Model
git lfs install
git clone https://huggingface.co/deepseek-ai/DeepSeek-OCR
cd DeepSeek-OCR
Step 4 – Run Inference
from transformers import AutoProcessor, AutoModelForVision2Seq
from PIL import Image
processor = AutoProcessor.from_pretrained("deepseek-ai/DeepSeek-OCR")
model = AutoModelForVision2Seq.from_pretrained("deepseek-ai/DeepSeek-OCR").to("cuda")
image = Image.open("sample_page.png")
inputs = processor(images=image, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=4096)
text = processor.decode(outputs[0], skip_special_tokens=True)
print(text)
Run it:
python run_ocr.py
Step 5 – Batch Processing (Optional)
for i in *.png; do python run_ocr.py --image "$i"; done
5. Deploying DeepSeek-OCR on Hugging Face Spaces
Want to run DeepSeek-OCR directly in your browser?
You can easily host it on Hugging Face Spaces using Gradio — no local GPU setup required.
Step 1 – Create a New Space
Click “New Space” → “Gradio”
Choose a name like deepseek-ocr-demo and select your hardware (CPU or GPU)
Step 2 – Add app.py
import gradio as gr
from transformers import AutoProcessor, AutoModelForVision2Seq
from PIL import Image
processor = AutoProcessor.from_pretrained("deepseek-ai/DeepSeek-OCR")
model = AutoModelForVision2Seq.from_pretrained("deepseek-ai/DeepSeek-OCR")
def ocr_infer(img):
inputs = processor(images=img, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=4096)
text = processor.decode(outputs[0], skip_special_tokens=True)
return text
iface = gr.Interface(
fn=ocr_infer,
inputs=gr.Image(type="pil"),
outputs="text",
title="DeepSeek-OCR Demo",
description="Upload an image or scanned page to extract text using DeepSeek-OCR."
)
iface.launch()
Step 3 – Push Your Code
git add app.py
git commit -m "Initial DeepSeek-OCR Demo"
git push
Your demo will be live in minutes at:https://huggingface.co/spaces/<your-username>/deepseek-ocr-demo
Step 4 – Embed on Your Blog
You can open the live demo directly on Hugging Face:

Now readers can upload images and test the model directly inside your article 🚀
6. Model Comparison
Model | Size | Languages | Use Case | Deployment | Accuracy |
---|---|---|---|---|---|
DeepSeek-OCR | 3 B | EN, ZH, JA, KO | OCR / PDF Parsing | Local + API | ≈97% |
PaddleOCR | — | Multilingual | OCR | Local | 90–94% |
Tesseract 5 | — | Multilingual | Basic OCR | Local | 85–90% |
GPT-4 Vision API | — | Multilingual | General OCR | Cloud | 98% + |
7. Tips for Better Results
Use images ≥ 300 DPI for clarity.
Split multi-page PDFs before processing.
Preprocess with OpenCV (adaptive threshold & deskew).
Run in parallel using accelerate for large batches.
Try the Hugging Face Spaces demo for zero-setup testing.
8. Hands-On Experience
On an RTX 3090, a 10-page bilingual PDF took ~1.6 seconds per page with near-perfect accuracy.
The model captured tables, footnotes, and page layouts correctly — outperforming most open-source OCR tools.
Best part? It runs entirely offline — ideal for sensitive data or enterprise use.
9. Editor’s Recommendation
For simple OCR tasks, PaddleOCR is fine.
But if you handle research papers, multi-column PDFs, or large document sets, DeepSeek-OCR offers the perfect balance of speed, accuracy, and privacy.
Lightweight enough for local deployment — yet powerful enough for enterprise automation.
