How to prompt Stable Diffusion XL

Tips that work on this model. The prompts under the samples above are good places to start.

Tips

  • Keep prompts compact: the subject, the setting, the light, then "photo".
  • Use the negative prompt to remove blur, text, or extra limbs.
  • Name the lens for portraits (85mm) and use "wide angle" for landscapes.
  • Start from an input image when the composition must stay put.
