Generate commercial-safe images from a plain text prompt. For a first request on CometAPI, send prompt, keep num_results at 1, and start with aspect_ratio: "1:1" unless you already know the final layout you need.

​
Use this route when

  • You want a finished image in one call
  • You do not need masks, image inputs, or task polling
  • You want a photorealistic Bria path that is easier to operationalize through CometAPI

​
Start with this request

  • Keep the prompt short and concrete
  • Use num_results: 1 for your first request
  • Start with aspect_ratio: "1:1" unless the target layout is already fixed
  • Download returned URLs promptly if you need long retention

​
Response behavior on CometAPI

Bria’s official docs describe a broader generation pipeline and discuss async status flows. On CometAPI, this route uses a simplified JSON request and returns a final result array immediately rather than a request_id plus status_url.
CometAPI proxies Bria capability rather than mirroring Bria’s public API field-for-field. Use the request and response shapes shown in this page’s API reference and Playground as the source of truth for integration.
