Source description

My attempt at a straightforward upscaling workflow utilizing SUPIR. This workflow was created with the initial intent of restoring family photos, but it is not at all limited to that use case. Can be complemented with ComfyUI Fooocus Inpaint Workflow for correcting any minor artifacts. (None of the images showcased for this model are touched up so as to accurately display its capabilities as a standalone process.)

My current preference for checkpoint to use with this workflow is HelloWorld XL v7 and for upscaling model either 4xRealWebPhoto v4 DAT2 or 4xUltrasharp .

Based on my own usage this workflow should be able to run on 8gb of vram on the preset settings. Some additional setting considerations if you have capable hardware:

Experiment with disabling fp8_unet and/or enabling high vram on the SUPIR model loader.

In the SUPIR sampler you'll likely want to enable keep_model_loaded (especially if you don't plan to load more models downstream needing to free up vram for them).

You can also bypass the downscaling step (image resize node) in the upscale group.

I'd recommend using ComfyUI-Manager for installing and updating any other custom nodes used within the workflow.

AI-generated commentary

AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.

Purpose

  • Use this ComfyUI workflow to upscale images with SUPIR, including family photos; it takes an image, a checkpoint, and an upscaling model and produces an upscaled image.

Flow

  • For minor artifacts, the author suggests pairing it with ComfyUI Fooocus Inpaint Workflow.

Inputs and outputs

  • The author's preferred checkpoint is HelloWorld XL v7; preferred upscalers are 4xRealWebPhoto v4 DAT2 or 4xUltrasharp.

  • SDXL 1.0 is listed as the base model.

Setup

  • The author recommends ComfyUI-Manager for installing and updating other custom nodes used in the workflow.

    Suggestion

Dependencies

  • The workflow lists 4xRealWebPhoto_v4.safetensors as an upscaler; verify that you have the matching file, since no hash or source link is listed.

    Suggestion

Configuration

  • For capable hardware, the author suggests trying fp8_unet disabled, high vram enabled on the SUPIR model loader, or both.

    Suggestion · not verified

  • The author suggests enabling keep_model_loaded in the SUPIR sampler; you can also bypass the downscaling step in the upscale group.

    Suggestion · not verified

Cautions

  • The author reports that preset settings should run on 8 GB of VRAM based on personal use; check this on your system.

    Suggestion · not verified

  • No license is stated in the listing, so check the reuse terms before using it.
