• Ultra high-consistency image upscale, up to 8k resolution in 12G memory.
• Especially good when you don't want to wildly change your character's face.
• 4x upscaling demo, denoising strength=0.4: comparison 1, comparison 2
• Compare to Ultimate SD Upscale, the algorithm is much more faithful to the original image and produces significantly fewer artifacts. See the Comparison with Ultimate SD Upcaler (at its optimal denoising strength=0.3) comparison 1, comparison 2

⚠ Instead of generating an 8k image at once, you should first try the default parameters with a small image and a small upscale factor (i.e., 1.5) to see if it works. ⚠ Generally, the denoising strength needs to be <= 0.6. It is not very sensitive to CFG values, so you can try it free.
