Upscale an image with Clarity AI’s Crystal Upscaler, a high-fidelity upscaler that stays faithful to the original while restoring faces, skin, and fine texture. The image is sent to Clarity AI’s API and the upscaled result is returned as an image. Selecting a model reveals the parameters specific to that model.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	Model to use. Selecting a model reveals the parameters specific to it: `image`, `scale_factor`, and `creativity`.	DYNAMIC_COMBO	Yes	`"crystal-upscaler"`
`image`	The image to upscale. Must contain exactly one image; image batches are not supported.	IMAGE	Yes	N/A
`scale_factor`	Factor to multiply the image width and height by. The output is limited to 100 megapixels (default: 2.0).	FLOAT	Yes	1.0 to 200.0 (step 0.1)
`creativity`	Higher values let the model reconstruct more detail instead of strictly preserving the original. Has no effect on images whose shorter side is 256 pixels or less (default: 0).	INT	Yes	0 to 10

Note: The input image must be at least 2x2 pixels. The output is capped at 100 megapixels and 65535 pixels per side; a larger result raises an error, so use a smaller image or a lower scale_factor.
