Pros & Cons 优缺点
✓ Pros优点
- High-quality PDF to Markdown conversion achieving ~95% accuracy on structured PDFs (vs ~70% for PyPDF2)
- Preserves tables, formulas, and multi-column layouts that naive text extraction destroys
- Supports batch processing of hundreds of PDFs via CLI
✕ Cons缺点
- GPU inference requires 4GB+ VRAM for acceptable speed; CPU mode is ~5-10x slower
- Complex scanned PDFs with low-resolution images require OCR preprocessing for best results
- Output quality depends heavily on source PDF quality — poorly formatted PDFs still produce messy output
