  • Image generation

GPT Image 1.5 creates images from a text prompt and edits images you provide. You can set quality, aspect ratio, number of images, a transparent background, output format and how closely an edit should preserve the input image, which makes it practical for product images, illustrations and image edits.

It is priced per run by quality, with the range shown on this page. Through Hormouz you call it with POST /v1/predictions and fetch the finished images from the returned links.

Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
