1. NMKD Superscale
   4x
   ESRGAN
   Purpose: Clean Real-World Images
   Upscaling of realistic images/photos with noise and compression artifacts

2. SPANkendata
   4x
   SPAN
   Purpose: Intended as a pretrain model, can be used to upscale undegraded photos.
   4x realistic upscaler that may also work for general purpose usage. Trained on Bicubic downscaled tiles from very high quality images.

3. 4xNomos8kSCHAT-L
   4x
   HAT
   4x photo upscaler with otf jpg compression and blur, trained on musl's Nomos8k_sfw dataset for realisic sr. Since this is a big model, upscaling might take a while.

6. UltraSharp
   4x
   ESRGAN
   It generates lots and lots of detail and leaves a nice texture on images. It works on most images, whether compressed or not. It does work best on JPEG compression though, as that's mostly what it was trained on. It has the ability to restore highly compressed images as well!

7. 4xPurePhoto-RealPLSKR
   4x
   RealPLKSR
   Skilled in working with cats, hair, parties, and creating clear images. Also proficient in resizing photos and enlarging large, sharp images. Can effectively improve images from small sizes as well (300px at smallest on one side, depending on the subject). Experienced in experimenting with techniques like upscaling with this model twice and then reducing it by 50% to enhance details, especially in features like hair or animals.
