Frequently asked questions
What makes a good FLUX 3 Klein prompt?
Concrete nouns, one clear scene, and explicit style words. Name the subject, the action, the environment, the lighting, and the rendering style — in that order — and keep it to one or two sentences.
How long should a prompt be?
One to three sentences. Longer prompts dilute attention; shorter prompts leave the style to chance. The gallery examples on this page all land in the sweet spot.
Can I use these prompts commercially?
Prompts are not copyrightable, and images you generate are governed by the model license of the service you use. Check the FLUX 3 Klein license terms for commercial-use conditions.
