Flux

Flux is a family of advanced text-to-image AI models developed by Black Forest Labs, founded by the original creators of Stable Diffusion. The Flux model lineup includes Flux.1 Pro for maximum quality, Flux.1 Dev for open-source development use, and Flux.1 Schnell for ultra-fast generation. Flux has quickly earned recognition for its exceptional prompt adherence, producing images that closely match complex textual descriptions including spatial relationships, multiple subjects, and specific artistic styles. The models demonstrate strong capabilities in rendering human anatomy, hands, and faces with fewer artifacts than many competitors. Flux.1 Dev and Schnell are available as open-source models that can be run locally or on custom infrastructure, giving developers and researchers full control over their image generation pipeline. The Pro model is available through the Black Forest Labs API and various third-party platforms including Replicate and fal.ai. Flux supports ControlNet conditioning, LoRA fine-tuning for custom styles, and img2img workflows. The architecture uses a novel flow-matching approach that produces high-quality results with fewer denoising steps, enabling faster generation without sacrificing detail. Flux has become the preferred base model for many AI art communities.
