AuraSR

AuraSR is a GAN-based super-resolution tool built on ideas from the GigaGAN paper. It takes low-resolution images and upscales them to 4x their original resolution, bringing back detail and sharpness that was missing before.

The upscaling can be applied repeatedly, so you can push images even further when you need more resolution. This makes it easy to rescue small pictures that would otherwise look soft or pixelated.

AuraSR excels at upscaling images generated by text-to-image models, which often come out at modest sizes. Better still, there are no limitations on resolution or upscaling factor, so you can enhance any image you like.
