FLUX-1

You type a text prompt, pick a size or aspect ratio, and FLUX-1 returns an image. FLUX-1 is an AI image generator built around a family of models, so you choose the one that suits the job.

FLUX.1 Schnell is the fast one.

FLUX.1 Dev and Schnell are both open-source for non-commercial use, which makes them easy to try if you want to experiment on your own terms.

FLUX.1 Pro is not open-source.

Commercial use of Schnell needs a different version, so check the licence before putting results into paid work.

The strengths are visual quality, close adherence to the prompt, and a good spread of different outputs from similar requests.

The catches are familiar for text to image models.

Complex scenes can trip it up, and very specific requests may take several attempts to get right.
