FLUX1.1 [pro]
FLUX1.1 [pro] is Black Forest Labs' flagship text-to-image model, released alongside the BFL API for developers and enterprises. It generates images six times faster than FLUX.1 [pro] while improving image quality, prompt adherence, and output diversity.
The model topped the Artificial Analysis image arena benchmark under the codename "blueberry," earning the highest overall Elo score among text-to-image models at launch. It supports ultra high-resolution generation up to 2k without sacrificing prompt following, and is available through the BFL API as well as third-party platforms including Together.ai, Replicate, fal.ai, and Freepik.
Black Forest Labs, founded by researchers behind Stable Diffusion and Latent Diffusion, builds foundational visual intelligence models from labs in Freiburg and San Francisco. The BFL API offers pay-as-you-go pricing with customization options for model choice, image resolution, and content moderation.
