Tips
- Topaz produces the best results but is the most expensive. Use for hero images and final deliverables.
- SeedVR is the best value — excellent quality at a fraction of Topaz’s cost.
- CCSR and Aura-SR are effectively free on fal (varg charges 5 credits for the API overhead). Good for batch processing.
- Combine with Phota Enhance if you need identity-preserving upscaling for faces.
