## Tips

- There are no options: if you need white/green/blur backgrounds or reverse mode, use 851-labs Background Remover (2cr)
- For the highest edge fidelity on hair and fine details, compare with BiRefNet
- Pairs well with an upscaler afterwards — alpha-preserving Bria Increase Resolution keeps the transparency
