What it does
Black Forest Labs' own demo of FLUX.2, which follows prompts more faithfully and renders finer detail than the previous generation. Nothing to install and no account. As with FLUX.1, the dev release is non-commercial, so output cannot be used for paid work without the vendor's separate commercial terms. FLUX.1 remains in use because of the large ecosystem of style add-ons built around it.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
