Crystal Upscaler

High-precision image upscaler specialized for portraits and faces, powered by Clarity AI

Model Overview

High-precision image upscaler optimized for portraits and faces, designed to enhance resolution while preserving important details like facial features.

Best At

Upscaling portrait and face-centric images to higher resolutions with minimal artifacts. Excels at preserving natural skin tones, eye details, and facial textures when magnifying.

Limitations / Not Good At

Struggles with non-face-centric images or extreme scaling factors (e.g., 6x+) that may cause softening or unnatural textures in non-facial areas. May not improve already high-quality images and can sometimes introduce subtle noise.

Ideal Use Cases

Up-sizing historical portrait photos, enhancing face details in marketing material, refining meme images, or boosting facial clarity in product mockups.

Input & Output Format

Accepts an input image (via URI or base64) and an optional scale factor (number). Returns an array containing a single URI pointing to the upscaled result image.

Performance Notes

Fast for moderate scale factors (2x-3x). Takes longer with higher resolutions (e.g., 6x) and larger input images. Requires significant GPU memory for high-scale operations
