topaz/upscale/image/precision
Upscale Image Precision is Topaz Labs's intelligent image editing model. Transform, retouch, and reimagine existing images using text prompts - from background replacement to artistic style conversion.
Input
Url of the image to be upscaled
0.011
Enhancement strength (0.01-1.0). Applies to Text Refine model only. Range: 0.01 to 1.
Output format of the upscaled image. Allowed values: jpeg, png.
01
Denoising level (0.0-1.0). Default varies by model. Range: 0 to 1.
01
Creativity level for face enhancement. 0.0 means no creativity, 1.0 means maximum creativity. Ignored if face enhancement is disabled. Range: 0 to 1.
01
Strength of the face enhancement. 0.0 means no enhancement, 1.0 means maximum enhancement. Ignored if face enhancement is disabled. Range: 0 to 1.
01
Compression artifact removal level (0.0-1.0). Not supported by the CGI model. Range: 0 to 1.
14
Factor to upscale the image by (e.g. 2.0 doubles width and height) Range: 1 to 4.
Whether to apply face enhancement to the image.
Subject detection mode for the image enhancement. Allowed values: All, Foreground, Background.
01
Sharpening level (0.0-1.0). Default varies by model. Range: 0 to 1.
Precision upscaling model. Standard V2 fits most photos; High Fidelity V3/V2 preserve detail in professional shots; Low Resolution V2 recovers compressed sources; CGI targets art and rendered graphics; Text Refine keeps text and shapes crisp. Allowed values: Standard V2, High Fidelity V3, High Fidelity V2, Low Resolution V2, CGI, Text Refine.

Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read
outputsfrom the completed response
