creative_upscale
Enhance image quality by upscaling resolution and refining details, especially for faces, using advanced Recraft AI technology. Accepts image URLs or local paths for processing.
Instructions
Creative upscale of the input image using Recraft. This operation takes an input image and returns an upscaled image, boosting resolution with a focus on refining small details and faces. This version of upscale is expensive and slower than crisp upscale. Local path or URL to resulting image and its preview will be returned in the response.
