Generation prompt. At most 8000 characters.

Number of outputs generated per job. Only 1 is supported.

enhance_promptboolean

Rewrite the prompt before generation. An LLM expands it into a fuller description and the model receives that text instead of the submitted one; the result's `prompt` reports what ran.

imagesarray

Images to edit or blend; omit to render from the prompt alone. 1 to 3 images, each at most 30 MB.

aspect_ratiostringrequired

Output aspect ratio.

resolutionstringrequired

Output resolution.

output_formatstring

Output image format.
