Flux

Open-weight image generation models from the original Stable Diffusion founders with photorealistic 4MP output

Flux is a family of image generation models created by Black Forest Labs, founded by the original creators of Stable Diffusion. With over 400 million downloads on Hugging Face, Flux has become one of the most widely-used image generation platforms. The FLUX.2 family delivers photorealistic images up to 4MP resolution with exceptional handling of hands, faces, fabrics, and small objects. FLUX.2 klein models generate images in under 1 second. The 4B klein model is fully open (Apache 2.0) for commercial use. Multi-reference features enable consistent character/object generation across scenes.
