Dev's current description of Upscayle "AI": "Free yourself from all the constraints. Upscayl is now everywhere! No more long loading times, hardware issues or quality compromises! . . . With state of the art AI, Upscayl helps you turn low resolution images into high resolution. Crisp and sharp! • Upscayl anywhere, anytime, any device • No GPU or hardware required • Face Enhancement • 10+ models to choose from • 5x faster than Upscayl Desktop • Video Upscaling • Commercial Usage • 5+ Modes • Fully Customizable • Free and Open Source" - - Despite the above, the FAQ states: "Q: Do I need a GPU for this to work?
A: Yes, unfortunately. NCNN Vulkan requires a Vulkan-compatible GPU. Upscayl won't work with most iGPUs or CPUs. But hey, no harm in trying ;)" - - IOW: CONFUSION and GUESTIMATION, not unlike the general HYPE that is current "AI". <-- As such, be glad it's free. Consider it BETAWARE, IMHO. Be certain to keep your SOURCE image! THAT is what's accurate, not any AI reinterpretation.
