# DeepSeek OCR (VLLM)

> Advanced OCR with batch processing for multi-page PDFs

## What is DeepSeek OCR?

DeepSeek OCR provides optimized batch processing for multi-page PDFs, processing all pages in a single batch for better performance.

## Usage

```python theme={null}
from upsonic.ocr import OCR
from upsonic.ocr.layer_1.engines import DeepSeekOCREngine
# Also available: from upsonic.ocr import DeepSeekOCREngine

# Create DeepSeek engine
engine = DeepSeekOCREngine(
    model_name="deepseek-ai/DeepSeek-OCR",
    temperature=0.0,
    max_tokens=8192
)

# Create OCR orchestrator
ocr = OCR(layer_1_ocr_engine=engine)

# Automatically uses batch processing for PDFs
result = ocr.process_file('multi_page_document.pdf')
print(f"Processed {result.page_count} pages")
```

## Parameters
