What is FLUX?

FLUX is a family of image generation models from Black Forest Labs (founded by Stable Diffusion creators) that achieves state-of-the-art quality on photorealism, typography, and compositional accuracy. FLUX.1 Pro and FLUX.1 Dev are available via API and open weights respectively.

Our Review

FLUX has rapidly displaced Stable Diffusion XL as the preferred open model for quality-focused workflows. The text rendering is genuinely excellent — a long-standing weakness of image generation models. For teams needing the best open-weights image model, FLUX.1 Dev is the clear choice; FLUX.1 Pro rivals Midjourney via API.

Product photography and marketing visuals
