01
What it is
PixelDiT (NVIDIA PiD) is an open-weight super-resolution model. It enlarges a picture four times in a single four-step pass and keeps what is there rather than redrawing it, which makes it the smoother choice for clean renders and photos that just need more pixels.
It is the second option in Upscale Image, next to Qwen 2.1 Restore. The app picks the tier from the input: pictures up to 512 pixels on the long edge go to 2048, larger ones to 4096.
