Default Model
This model is the default upscaling model used with UpscalerJS. It is a copy of the 2x model made available via @upscalerjs/esrgan-slim.
Samples + Demo
Here are some examples of upscaled images using this model.

Usage
@upscalerjs/default-model comes pre-installed with upscaler. It is the default model when no model is provided:
import UpscalerJS from 'upscaler';
const upscaler = new UpscalerJS(); // Using the default-model
If for some reason you wish to provide it explicitly, you can do so:
import UpscalerJS from 'upscaler';
import model from '@upscalerjs/default-model';
const upscaler = new UpscalerJS({
model,
})
