What is SUPIR?
SUPIR (Scaling Up to Photorealistic Image Restoration) uses an SDXL backbone for upscaling — restoring fine detail by literally redrawing it instead of interpolating. Heavier than Real-ESRGAN by an order of magnitude but the photorealistic detail recovery on real photos is in a different class.
Pros & cons
✓ PROS
- Reconstructs detail rather than interpolating — best for photos
- Strong prompt conditioning for guided restoration
- ComfyUI nodes available — fits straight into existing pipelines
– CONS
- 16 GB VRAM minimum, 24 GB+ comfortable
- Slow vs. Real-ESRGAN — minutes vs. seconds
- Non-commercial licence
What's actually free?
Non-commercial research licence; weights & code public.
