In the realm of AI image upscaling, two names that often come up are Nightmareh and novita.ai. Both offer promising solutions to enhance image quality using AI, but how do they stack up against each other? Let's dive in.

## What is Nightmare AI Image Upscaler?
Nightmareh's AI image upscaler, known as Real-ESRGAN, is a powerful tool that not only upscales images but also offers optional face correction and adjustable upscale. It uses the ESRGAN (Enhanced Super-Resolution Generative Adversarial Networks) model, which is known for its ability to generate realistic textures during upscaling.

One of the standout features of Nightmareh's upscaler is its face enhancement option. This feature is particularly useful for images of faces, as it can enhance facial features during the upscaling process, resulting in clearer and more detailed faces.
