About Flux 1.1 Pro

Flux 1.1 Pro, developed by Black Forest Labs, is an image generation model with 12 billion parameters built by the original team behind Stable Diffusion. The model produces high-quality images from text descriptions with excellent prompt adherence, fast generation times, and strong compositional accuracy. Founded by Robin Rombach and others who created the latent diffusion approach used in Stable Diffusion, Black Forest Labs brings deep expertise in diffusion model architecture to Flux. The model competes directly with Midjourney and DALL-E 3 on image quality while offering more flexible API-based access at approximately $0.04 per image. Flux 1.1 Pro supports various aspect ratios, styles, and use cases from photorealism to illustration. Its combination of quality, speed, and accessible API pricing has made it a popular choice for production image generation applications.
