    <p>This is an online demo of SUPIR, a practicing model scaling for photo-realistic image restoration.
    It is still a research project under tested and is not yet a stable commercial product.
    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 only last few minutes.
    This demo can handle huge images but the process will be aborted if it lasts more than 10 min.
    If you want to upscale AI-generated images, be noticed that <i>Stable Diffusion Medium</i> spaces can directly generate 1536x1536 images.
    Please leave a <a href="https://huggingface.co/spaces/Fabrice-TIERCELIN/SUPIR/discussions/new">message in discussion</a> if you encounter issues.

## **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).
