    <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>.
    The aim of SUPIR is the beauty and the illustration.
    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 8 min.
    Please <a href="https://huggingface.co/spaces/Fabrice-TIERCELIN/SUPIR/discussions/new">leave a 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).
