    <p>This is an online demo of SUPIR, a practicing model scaling for photo-realistic image restoration.
    The content added by SUPIR is <b><u>imagination, not real-world information</u></b>.
    SUPIR is for beauty and illustration only.
    Most of the processes last few minutes.
    If you want to upscale AI-generated images, be noticed that <i>PixArt Sigma</i> space can directly generate 5984x5984 images.
    Due to Gradio issues, the generated image is slightly less satured than the original.
    Please leave a <a href="https://huggingface.co/spaces/Fabrice-TIERCELIN/SUPIR/discussions/new">message in discussion</a> if you encounter issues.
    You can also use <a href="https://huggingface.co/spaces/gokaygokay/AuraSR">AuraSR</a> to upscale x4.

## **Piracy**
The images are not stored but the logs are saved during a month.
## **How to get SUPIR**
You can get SUPIR on HuggingFace by [duplicating this space](https://huggingface.co/spaces/Fabrice-TIERCELIN/SUPIR?duplicate=true) and set GPU.
You can also install SUPIR on your computer following [this tutorial](https://huggingface.co/blog/MonsterMMORPG/supir-sota-image-upscale-better-than-magnific-ai).
You can install _Pinokio_ on your computer and then install _SUPIR_ into it. It should be quite easy if you have an Nvidia GPU.
