Task Submission Parameters
Request Parameters
| Parameter | Type | Required | Default | Range | Description |
|---|---|---|---|---|---|
| prompt | string | Yes | - | The positive prompt for the generation. | |
| size | string | No | auto | auto, 1024*1024, 1024*1536, 1536*1024 | The size of the generated media in pixels (width*height). |
| quality | string | No | medium | low, medium, high | The quality of the generated image. |
| background | string | No | opaque | auto, transparent, opaque | Background for the generated image |
| output_format | string | No | jpeg | jpeg, png | The format of the output image. |
| enable_sync_mode | boolean | No | false | - | If set to `true`, the request attempts to wait for the generated result and return outputs in the same response. If the result is not ready within the sync wait window, the API can return a timeout body while the task continues processing. This option is only available via the API and is supported only by some models. |
| enable_base64_output | boolean | No | false | - | If set to `true`, the prediction's `output` strings are returned as **naked base64** (no `data:<mime>;base64,` prefix). When `false` (default), outputs are returned as URLs pointing to our CDN. |
