Pruned models in safetensors format now available here: https://huggingface.co/Kijai/SUPIR_pruned/tree/main
Added a better way to load the SDXL model, which also allows using LoRAs. The old node will remain for now to not break old workflows, and it is dubbed Legacy along with the single node, as I do not want to maintain those.
As I have learned a lot with this project, I have now separated the single node to multiple nodes that make more sense to use in ComfyUI, and makes it clearer how SUPIR works. This is still a wrapper, though the whole thing has deviated from the original with much wider hardware support, more efficient model loading, far less memory usage and more sampler options. Here's a quick example (workflow is included) of using a Ligntning model, quality suffers then but it's very fast and I recommend starting with it as faster sampling makes it a lot easier to learn what the settings do.
Under the hood SUPIR is SDXL img2img pipeline, the biggest custom part being their ControlNet. What they call "first stage" is a denoising process using their special "denoise encoder" VAE. This is not to be confused with the Gradio demo's "first stage" that's labeled as such for the Llava preprocessing, the Gradio "Stage2" still runs the denoising process anyway. This can be fully skipped with the nodes, or replaced with any other preprocessing node such as a model upscaler or anything you want.

Either manager and install from git, or clone this repo to custom_nodes and run:
pip install -r requirements.txt
or if you use portable (run this in ComfyUI_windows_portable -folder):
python_embeded\python.exe -m pip install -r ComfyUI\custom_nodes\ComfyUI-SUPIR\requirements.txt
Pytorch version should be pretty new too, latest stable (2.2.1) works.
xformers is automatically detected and enabled if found, but it's not necessary, in some cases it can be a bit faster though:
pip install -U xformers --no-dependencies (for portable python_embeded\python.exe -m pip install -U xformers --no-dependencies )
Get the SUPIR model(s) from the original links below, they are loaded from the normal ComfyUI/models/checkpoints -folder
In addition you need an SDXL model, they are loaded from the same folder.
I have not included llava in this, but you can input any captions to the node and thus use anything you want to generate them, or just don't, seems to work great even without.
Memory requirements are directly related to the input image resolution, the "scale_by" in the node simply scales the input, you can leave it at 1.0 and size your input with any other node as well. In my testing I was able to run 512x512 to 1024x1024 with a 10GB 3080 GPU, and other tests on 24GB GPU to up 3072x3072. System RAM requirements are also hefty, don't know numbers but I would guess under 32GB is going to have issues, tested with 64GB.
- fp8 seems to work fine for the unet, I was able to do 512p to 2048 with under 10GB VRAM used. For the VAE it seems to cause artifacts, I recommend using tiled_vae instead.
- CLIP models are no longer needed separately, instead they are loaded from your selected SDXL checkpoint
