FLUX is a family of state-of-the-art text-to-image generation models built by Black Forest Labs, the German research lab founded by the original creators of Stable Diffusion. The current flagship, FLUX.2, delivers production-grade image generation with consistent characters and styles, physics-aware composition, adaptive lighting, and precise text-guided editing (style transfer, object replacement, and in-context edits via FLUX Kontext). FLUX is offered through a no-code browser Playground, a pay-as-you-go API for developers shipping at scale, and open-weight model licenses for self-hosted deployment via Hugging Face and GitHub. Backed by a $300M Series B round and partnerships with Microsoft, Adobe, and Freepik, FLUX has become one of the most widely adopted image models across creative and enterprise workflows.
