About FLUX 1.1 Pro Ultra
FLUX 1.1 Pro Ultra is 1.1 Pro with the lid off the resolution — an Ultra mode that pushes output up to 4K. It’s what you use when the image is going on a wall, a poster, or a display where every pixel shows.
You keep the prompt accuracy and natural composition that make 1.1 Pro so good; you just get a lot more detail to print.
2 credits an image — genuinely cheap for something that can render at 4K.
