## 🔧 Technical Details

### DeepSeek-OCR Model:
- **Model**: `deepseek-ai/DeepSeek-OCR`
- **Type**: Image-text-to-text pipeline
- **Capability**: Extract text from document images
- **Accuracy**: High-quality OCR for legal documents

### Integration Points:
```python
# OCR Pipeline
self.ocr_pipeline = pipeline(
    "image-text-to-text", 
    model="deepseek-ai/DeepSeek-OCR", 
    trust_remote_code=True
)

# Process document
def process_document_with_ocr(self, image_path: str) -> str:
    result = self.ocr_pipeline(image_path)
    extracted_text = result[0]['generated_text']
    return extracted_text
```

## ⚠️ Important Notes

### Model Size:
- DeepSeek-OCR is a **large model**
- Requires significant GPU/CPU resources
- First load may take 1-2 minutes on HF Spaces

### Hardware Recommendations:
- **Free Tier**: Works but slower
- **CPU Upgrade**: Better performance
- **T4 GPU**: Best performance for OCR
