What is Flux?

FLUX is the family of image models from Black Forest Labs, the company founded by key Stable Diffusion researchers. The models quickly became a favorite for their prompt accuracy, sharp detail and convincing hands, lighting and text. Different versions trade speed against quality, from the lightning-fast Schnell edition to the high-end Pro tier used by professional platforms.

You can use FLUX through the company's own playground and API, through partner platforms such as fal and Replicate, or by running the open-weight versions locally for free. That flexibility made FLUX the default engine inside many other AI image apps. Licensing for hosted versions follows each provider's terms, so check before shipping commercial client work.
