Tips for your own prompts

  • Name the subject first, then where it is, then the light, then the style or camera.
  • Put words you want written in the image in quotes, and say where they go.
  • For an edit, say what to change and what to keep the same.
  • Keep to the image rules: no real people, no sexual or violent content, no characters or brands owned by others.

To run the model yourself instead, see ComfyUI and the hardware requirements.

Questions

Are these images made by FLUX 3 Klein?

This page lists prompts, not results. Press Try this prompt to make the image yourself; it uses one of your 3 free images a day.

Why are the prompts so long?

The FLUX 3 Klein model card says the model is meant to be used with a prompt upsampler, and that short prompts used directly give mediocre results. Spelling out the subject, setting, light and style does part of that work.

Can I use a prompt for an edit?

Yes. Switch the generator to Edit an image, upload your image, and describe the change, as in the last example on this page. Follow the image rules.
