AuraSR-ComfyUI Description

AuraSR-ComfyUI integrates the Aura-SR model into ComfyUI, enhancing image super-resolution capabilities within the user interface. It leverages advanced algorithms to improve image quality and detail.

AuraSR-ComfyUI Introduction

AuraSR-ComfyUI is an extension designed to integrate the powerful Aura-SR upscaling capabilities into the ComfyUI environment. This extension leverages advanced GAN-based Super-Resolution techniques to enhance the quality of real-world images, making them sharper and more detailed. For AI artists, this means you can take your creations to the next level by improving the resolution and clarity of your images without losing the original artistic intent.

AuraSR-ComfyUI is particularly useful for upscaling images generated by AI models, which often suffer from lower resolution. By using this extension, you can achieve high-quality, high-resolution outputs that are suitable for professional use, printing, or detailed analysis.

How AuraSR-ComfyUI Works

AuraSR-ComfyUI works by applying a sophisticated machine learning model to your images, enhancing their resolution. Think of it as a digital magnifying glass that not only enlarges your image but also fills in the details to make it look as if it was originally created at a higher resolution.

The extension uses a variation of the GigaGAN model, which is a type of Generative Adversarial Network (GAN). GANs consist of two neural networks: a generator and a discriminator. The generator creates high-resolution images from low-resolution inputs, while the discriminator evaluates the quality of these images. Through this process, the generator learns to produce increasingly realistic and detailed images.

AuraSR-ComfyUI Features

AuraSR-ComfyUI comes with several features designed to give you control over the upscaling process:

  • Upscaling Node: The core feature of AuraSR-ComfyUI is the upscaling node, which you can add to your ComfyUI workflow. This node takes a low-resolution image and outputs a high-resolution version.
  • Transparency Mask: This optional feature allows you to maintain the transparency of your original images. If you load an RGBA image (an image with transparency), you can use a transparency mask to ensure the upscaled image retains its transparent areas.
  • Reapply Transparency: When using a transparency mask or an RGBA image, this feature attempts to reapply the original transparency to the upscaled image. This is particularly useful for images with transparent backgrounds or elements.


  • Model and Config Files: You can download the model and configuration files from and place them in the \models\Aura-SR folder. You can also rename these files to suit your needs, allowing for multiple models with unique configurations.
  • Compression Artifact Removal: If you are working with compressed images (like JPEGs), you can use a compression artifact-removal model such as DeJPG_OmniSR ( before passing the image to AuraSR. This helps in improving the quality of the final output.

AuraSR-ComfyUI Models

AuraSR-ComfyUI currently supports the Aura-SR model, which is designed for real-world image upscaling. This model is particularly effective for images that need significant enhancement in detail and resolution.

  • Aura-SR Model: Ideal for general-purpose upscaling, this model works well with a variety of images, from digital art to photographs. It is sensitive to image compression, so it's best to use uncompressed images for optimal results.

What's New with AuraSR-ComfyUI

Latest Updates

  • Initial Release: The first version of AuraSR-ComfyUI brings the powerful Aura-SR upscaling capabilities to ComfyUI. This release includes the core upscaling node, transparency mask support, and the ability to reapply transparency.

Troubleshooting AuraSR-ComfyUI

Here are some common issues you might encounter while using AuraSR-ComfyUI and how to solve them:

Common Issues and Solutions

  • Poor Quality Output: If the upscaled image looks bad, it might be due to image compression. Try using uncompressed images or apply a compression artifact-removal model like DeJPG_OmniSR before upscaling.
  • Transparency Issues: If the transparency is not retained in the upscaled image, ensure you are using a valid transparency mask or an RGBA image. Remember that the 'Load Image' node in ComfyUI converts images to RGB by default, so you might need a specialized node to handle RGBA images.

Frequently Asked Questions

  • Q: Can I use JPEG images with AuraSR-ComfyUI?
  • A: Yes, but JPEG images often have compression artifacts. It's recommended to use a compression artifact-removal model before upscaling.
  • Q: How do I maintain transparency in my images?
  • A: Use the transparency mask feature or ensure your image is in RGBA format and use the reapply transparency option.
