If your upscaled image appears blurry or shows artifacts, first check the quality and resolution of your input image. Extremely low-resolution or heavily compressed sources may not upscale cleanly, even with advanced AI. Try starting with the highest-quality version of your original image. If the issue persists, test a 2x upscale instead of 4x to see if the model performs better at a lower multiplier. Additionally, compare results with other JAI Portal upscalers like
Flux Vision Upscaler or
Ideogram Upscale, as different models handle textures, edges, and detail reconstruction differently. For portraits specifically,
Portrait Enhance may deliver superior facial detail. JAI Portal's side-by-side comparison tool helps you quickly identify the best upscaler for your content type.
