Flux1 AI is a web platform that gives you access to the FLUX family of image models — the technology originally developed by Black Forest Labs in Freiburg, Germany — without installing anything locally. You open the create page, pick a model such as FLUX.2 Pro, Flux 1.1 Pro Ultra, FLUX Krea or FLUX.1 Kontext, type a prompt or upload a photo, and most images are ready within seconds. Flux1 AI states clearly on its site that it is an independent platform and is not affiliated with, endorsed by or sponsored by Black Forest Labs; "FLUX" is a trademark of Black Forest Labs, and references to it on Flux1 AI describe the supported models only.
The model lineup covers several practical workflows. FLUX.2 Pro is positioned for photorealism, accurate text rendering inside images and strong prompt adherence. FLUX.1 Kontext Pro and Max let you edit an existing photo with a single sentence — swapping backgrounds, changing style or rewriting text while keeping the subject consistent. The FLUX utility tools (Fill, Canny, Depth and Redux) handle inpainting, outpainting, composition guidance and image variations. Alongside the FLUX models, one account also unlocks other image models such as Nano Banana Pro, GPT Image and Seedream, plus video models including Seedance, Kling and Veo, so you can compare results without juggling separate subscriptions.
Access is credit-based. New accounts receive a small number of free credits on sign-up — enough to try FLUX.2 Pro and other models — with no credit card required. Paid plans pool credits that can be spent across every model, and a developer API is offered for programmatic use. Images generated on a paid plan may be used in commercial projects according to the vendor's terms.
