Flux 1.1 Pro Ultra Text-to-Image
FLUX 1.1 Pro delivers fast text-to-image with excellent prompt adherence and output diversity, and an Ultra variant built for maximum precision.
Working with Flux 1.1 Pro
Flux 1.1 Pro is the premium text-to-image pair from the FLUX.1 generation: the Pro variant is faster and better than the original FLUX Pro with strong prompt adherence and output diversity, and Pro Ultra pushes precision further for demanding work.
When to choose Flux 1.1 Pro
Choose Flux 1.1 Pro when you want the proven premium FLUX.1 text-to-image quality without the size decisions of Flux 2. It generates only — editing lives in the Kontext and Flux 2 families.
Choosing between the variants
Pro is the fast, well-balanced default with strong prompt adherence. Pro Ultra is the higher-precision tier and the one to reach for when a shot has to be exactly right.
