Flux AI

Type a sentence describing a scene, pick a model, and get a finished image back without installing anything.

That is the basic job of Flux AI, a free online text-to-image generator that works with models such as flux.1 pro and flux.1 schnell.

The site also accepts prompts in German and other languages, which helps if English is not your first choice for describing what you want.

As an AI image generator, Flux AI lists several capabilities: multi-modal input, ultra-high resolution output, a range of visual styles, real-time rendering and more accurate anatomy in people, a common weak spot in image models.

Output is described as suitable for commercial use, though you should read the terms yourself before putting images into client work.

Pricing is free, so trying Flux AI costs nothing beyond your time.

Having both a pro and a schnell model is useful: you can pick whichever suits the job, whether that is a polished render or a quick draft while you refine a prompt.
