# Generate a Bria image
> Use CometAPI Bria POST /bria/text-to-image to generate 1MP photorealistic images from text with enhancements and flexible aspect ratios.
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.
