Why DALL·E 3 prompts are different

DALL·E 3 is a natural-language model. It reads full sentences — not keyword lists, not parameter flags. A prompt like "a cat, oil painting, vintage, detailed" works in Midjourney but underperforms in DALL·E 3.

The same idea for DALL·E 3 should read:

An oil painting of a calico cat lounging on a vintage Persian rug, soft afternoon light through lace curtains, detailed brushstrokes in the style of late 19th-century Impressionist interiors.

Reprompte generates this format automatically when you select DALL·E as the platform.

DALL·E 3 prompt best practices

  • ✓Write in full sentences — DALL·E 3 parses grammar and context, not keyword piles.
  • ✓Specify artistic medium — "oil painting", "watercolor", "3D render", "photograph".
  • ✓Describe lighting explicitly — "golden hour", "studio softbox", "moody chiaroscuro".
  • ✓Use positive phrasing for exclusions — say "empty street, no cars" rather than a negative-prompt field.
  • ✓Keep prompts 30-60 words — longer prompts get auto-truncated by DALL·E 3.
  • ✗Don't use Midjourney parameters — --ar 16:9 is ignored by DALL·E 3.
