FLUX is a family of image generation models by Black Forest Labs (founded by the original Stable Diffusion team) that has rapidly become a benchmark-setter for photorealism and prompt adherence. FLUX.1 Pro and FLUX.1 Dev are available via API, while FLUX.1 Schnell is open-source under the Apache 2.0 licence. The models are state-of-the-art at rendering hands, faces, and complex scenes. Widely integrated into third-party platforms including ComfyUI, Replicate, and FAL.ai.
