About FLUX Pro 1.1

FLUX Pro 1.1 is Black Forest Labs' production-grade text-to-image model, the version that established FLUX's reputation for clean, high-quality output across photographic, editorial, and stylized work. It's a strong general-purpose model with reliable prompt adherence and a distinctive FLUX aesthetic that many creators specifically seek.

Compared to FLUX 2 Flex, FLUX Pro 1.1 is simpler, no guidance scale or inference step controls, just prompt-in / image-out. That makes it faster to iterate with and cheaper per generation. It supports prompt enhancement (auto-rewriting your prompt for better results) and seed control for reproducible outputs.

On DesignerBox, FLUX Pro 1.1 costs 5 credits per generation, with up to 4 images per batch. Use it as a workhorse for general image generation when you don't need FLUX 2 Flex's parameter control or Nano Banana Pro's premium tier.

Best For

General-purpose image generation, photographic and editorial work, batch iteration with reliable quality, and any creator who specifically wants the distinctive FLUX aesthetic.
