## Model overview

`real-esrgan-a100` is an image upscaling model developed by [daanelson](https://aimodels.fyi/creators/replicate/daanelson) that aims to provide practical algorithms for general image restoration. It extends the powerful ESRGAN model to a practical restoration application, trained with pure synthetic data. The model performs well on a variety of images, including general scenes and anime-style artwork. It can be compared to similar models like [real-esrgan](https://aimodels.fyi/models/replicate/real-esrgan-nightmareai) and [real-esrgan-xxl-images](https://aimodels.fyi/models/replicate/real-esrgan-xxl-images-sfarrowgr), which also offer advanced image upscaling capabilities.

## Model inputs and outputs

`real-esrgan-a100` takes a low-resolution image as input and outputs a high-resolution version of the same image. The model is optimized to handle a wide range of image types, including standard photos, illustrations, and anime-style artwork.

### Inputs
- **Image**: The low-resolution input image to be upscaled.
- **Scale**: The factor by which the image should be scaled up, from 0 to 10. The default is 4x.
- **Face Enhance**: An optional flag to run GFPGAN face enhancement along with the upscaling.

### Outputs
- **Output Image**: The high-resolution version of the input image, upscaled by the specified factor and optionally with face enhancement applied.

## Capabilities

`real-esrgan-a100` is capable of producing high-quality upscaled images with impressive detail and clarity. The model is particularly adept at preserving fine textures and details, making it well-suited for upscaling a variety of image types. It can handle both natural photographs and stylized artwork, producing impressive results in both cases.

## What can I use it for?

`real-esrgan-a100` can be used for a variety of image-related tasks, such as:

- **Enhancing low-resolution images**: Upscale and sharpen low-quality images to create high-resolution versions suitable for printing, digital display, or further processing.
- **Improving image quality for creative projects**: Use the model to upscale and enhance illustrations, concept art, and other types of digital artwork.
- **Preparing images for online use**: Upscale images while preserving quality to create assets for websites, social media, and other digital platforms.

## Things to try

When using `real-esrgan-a100`, you can experiment with different scale factors to find the optimal balance between image quality and file size. Additionally, the face enhancement feature can be a useful tool for improving the appearance of portraits and other images with prominent facial features.
