Overview

Turns a written description into a generated image, returned inline in the response rather than as a link that expires. The prompt is the whole interface: describe the subject, style, composition, and lighting in one string of up to a thousand characters and the model renders it. Generation is a single synchronous call, so the request stays open until the image is ready; a picture takes appreciably longer than a text completion.

The generated image, returned inline as base64 with its media type and size in bytes.

Input

These go in the input object of the run request.
