Tips for better results

  • Subject, action, setting and light

    A good prompt says what it is, what it is doing, where it is and what the light looks like. E.g. "an orange cat asleep on a windowsill, rain outside, soft morning light".

  • Be specific about the mood

    Words like "calm", "dramatic" or "cozy" change colors and composition more than you might expect.

  • Avoid text inside the image

    Letters and numbers still come out wrong. Generate a clean image and add text later in an editor.

  • Generate in the final format

    Creating in the right format avoids crops that ruin the composition.

  • Careful with real people and brands

    Do not generate images that imitate real people, logos or protected characters.
