Request body
10 properties · 1 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| prompt* | string | The prompt to generate an image from. | |
| acceleration | enum | The speed of the generation. The higher the speed, the faster the generation. | none | regular | high · default: "none" |
| enable_safety_checker | boolean | If set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked, and images flagged as unsafe are returned as black images. | default: true |
| sync_mode | boolean | If `True`, the media will be returned as a data URI and the output data won't be available in the request history. | default: false |
| num_images | integer | The number of images to generate. | 1 ≤ n ≤ 4 · default: 1 |
| image_size | ImageSize | enum | The size of the generated image. | default: "landscape_4_3" |
| num_inference_steps | integer | The number of inference steps to perform. | 1 ≤ n ≤ 12 · default: 4 |
| guidance_scale | number | The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you. | 1 ≤ n ≤ 20 · default: 3.5 |
| seed | integer | The same seed and the same prompt given to the same version of the model will output the same image every time. | nullable |
| output_format | enum | The format of the generated image. | jpeg | png · default: "jpeg" |
Types
1 $defsImageSizeobject
| height | integer | The height of the generated image. | 0 < n ≤ 14142 · default: 512 |
| width | integer | The width of the generated image. | 0 < n ≤ 14142 · default: 512 |
