Notes

Modes

  • Text-to-image: no images attached
  • Image-editing: upload 1-3 images

Constraints

  • Positive prompt: max 800 characters
  • Negative prompt: max 500 characters
  • Custom width/height: 512-2048 px (total area between 512x512 and 2048x2048)
  • Per image is billed

Performance

  • Responses take 10-30 seconds depending on resolution, image count, and prompt complexity

Content safety

  • Generated images pass an automated content-safety check. An image flagged as explicit is not returned. Because the image is generated before the check runs, a flagged generation is still billed.
