RefineArt Model Mirror
This repository serves as a model mirror for the RefineArt project, providing reliable access to the large model files required for 4K image enhancement using APISR and SUPIR pipelines.

APISR models are included in the main RefineArt repository under src/magine/libs/apisr/weights/.
Overview
RefineArt integrates two state-of-the-art super-resolution models:
- SUPIR (Scaling Up to Excellence for Photo-Realistic Image Restoration) - Designed for realistic photo enhancement
- APISR (Anime Picture Intelligent Super Resolution) - Specialized for anime and illustrations
Due to the large size of these model files and potential availability issues with the original sources, this repository acts as a reliable mirror to ensure smooth operation of the RefineArt application.
SUPIR Models
About SUPIR
SUPIR (Scaling Up to Excellence for Photo-Realistic Image Restoration) originates from the CVPR 2024 paper:
Fanghua Yu, Jinjin Gu, Zheyuan Li, Jinfan Hu, Xiangtao Kong, Xintao Wang, Jingwen He, Yu Qiao, Chao Dong. "Scaling Up to Excellence: Practicing Model Scaling for Photo-Realistic Image Restoration In the Wild." CVPR 2024.
Variants
- SUPIR-v0Q: Quality variant optimized for visual quality
- SUPIR-v0F: Fidelity variant optimized for preserving original details
- FP16 versions: Memory-efficient half-precision variants
- Full versions: Complete precision models
Required Dependencies

Usage
Automatic Download (Recommended)
The RefineArt project automatically downloads required models from this mirror during first execution:
When you run RefineArt for the first time, it will automatically download the required SUPIR models to:
refineart/src/magine/libs/supir/checkpoints/APISR models are included directly in the main repository at:
refineart/src/magine/libs/apisr/weights/
Manual Download
To manually download models for offline use:
Clone this repository:
git clone https://huggingface.co/dzhsurf/refineart-model-mirrorCopy the required model files to the appropriate directories in your RefineArt installation:
- SUPIR models:
refineart/src/magine/libs/supir/checkpoints/ - APISR models: Already included in
refineart/src/magine/libs/apisr/weights/
