Output

Output	Type	Description
Image	File	The generated image. DALL·E output is PNG; GPT Image follows Output Format.

Describe the subject, setting, composition, lighting, palette, and intended use. A specific art direction is more reliable than a list of adjectives.

GPT Image models support transparent backgrounds. Choose PNG or WebP when the downstream workflow must preserve transparency.
