Parameter Reference

Required Supported Not available

Media Inputs

Parameter	Type	Description	Modes
`image`	file	Required. Input image to upscale Single image per request.	Upscale
`scale_factor`	number	Required. Factor by which to upscale the image	Upscale

Output & Format

Parameter	Type	Description	Modes
`response_format`	string	How to return the image `url` `b64_json` Default: `"url"`	Upscale
`output_format`	string	Output image format `png` `jpeg` `gif` `webp` `avif` Gateway converts to requested format if provider doesn't support it natively.	Upscale
`output_compression`	integer	Compression level for lossy formats (JPEG, WebP, AVIF)	Upscale
`n`	integer	Number of images to generate Default: `1` Gateway generates multiple images in parallel even if provider only supports 1.	Upscale

Additional Parameters

Provider-specific passthrough fields, available only when the request is routed to the listed provider.

Parameter	Type	Description	Modes
Universal
`creativity`	number	Creativity level for upscaling	Upscale

Parameter Normalization

How we handle parameters across different providers

Not every provider speaks the same language. When you send a parameter, we handle it in one of four ways depending on what the model supports:

Behavior	What happens	Example
`passthrough`	Sent as-is to the provider	style, quality
`renamed`	Same value, mapped to the field name the provider expects	prompt
`converted`	Transformed to the provider's native format	size
`emulated`	Works even if the provider has no concept of it	n, response_format

Parameters we don't recognize pass straight through to the upstream API, so provider-specific options still work.

Overview

Crystal Upscaler is a high-precision super-resolution model developed by Clarity AI, specifically engineered to enhance the fidelity of portraits, facial features, and product photography. It distinguishes itself by supporting output resolutions up to 10K, allowing for significant upscaling factors while maintaining structural integrity. The model is designed to bridge the gap between low-resolution captures and high-definition print or digital display requirements.

Strengths

Facial Reconstruction: Excels at restoring micro-details in human faces, such as skin texture, iris definition, and hair strands, without introducing the “uncanny valley” artifacts common in generic upscalers.
High-Scale Factor: Supports ultra-high resolution outputs up to 10K, making it suitable for billboard-scale printing and large-format digital assets.
Edge Definition in Products: Maintains sharp, clean lines on product edges and packaging text, preventing the blurring or “bleeding” of colors often seen when blowing up small product shots.
Noise Reduction: Effectively filters out compression artifacts and sensor noise from the source image while simultaneously synthesizing missing high-frequency details.

Limitations

Generic Texture Hallucination: While optimized for specific subjects like faces and products, the model may struggle with complex, non-standard textures like abstract art or dense foliage, where it might hallucinate patterns that weren’t in the original.
Compute Requirements: Due to the 10K resolution ceiling, processing times for maximum-scale outputs are significantly higher than standard 2x or 4x upscalers.
Stylistic Rigidity: The model prioritizes realism and clarity; it is not intended for artistic style transfer or altering the fundamental composition of the input image.

Technical Background

Crystal Upscaler is built upon the Clarity AI framework, utilizing a specialized super-resolution architecture that emphasizes local feature refinement. The training regimen focused heavily on high-bitrate photographic datasets, specifically curated to teach the model the relationship between low-resolution pixel grids and high-fidelity skin and material textures. This enables the model to perform predictive detail synthesis rather than simple interpolation.

Best For

Crystal Upscaler is ideal for photographers needing to rescue “soft” portraits, e-commerce managers preparing product thumbnails for high-resolution displays, and print designers working with legacy assets. It is a reliable choice for any workflow requiring professional-grade clarity for human subjects.

Crystal Upscaler is available for testing and integration through Lumenfall’s unified API and interactive playground, providing a streamlined way to incorporate 10K upscaling into existing production pipelines.
