Request body
13 properties · 1 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| prompt* | string | The prompt to generate an image from. | |
| 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 |
| negative_prompt | string | The negative prompt to use. Use it to address details that you don't want in the image. This could be colors, objects, scenery and even the small details (e.g. moustache, blurry, low resolution). | default: "" |
| 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 |
| cfg_trunc_ratio | number | The ratio of the timestep interval to apply normalization-based guidance scale. | 0 ≤ n ≤ 1 · default: 1 |
| num_inference_steps | integer | The number of inference steps to perform. | 1 ≤ n ≤ 50 · default: 30 |
| enable_safety_checker | boolean | If set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked. | default: true |
| image_size | ImageSize | enum | The size of the generated image. | default: "landscape_4_3" |
| cfg_normalization | boolean | Whether to apply normalization-based guidance scale. | default: true |
| system_prompt | string | The system prompt to use. | default: "You are an assistant designed t… |
| 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. | 0 ≤ n ≤ 20 · default: 4 |
| output_format | enum | The format of the generated image. | jpeg | png · default: "jpeg" |
| num_images | integer | The number of images to generate. | 1 ≤ n ≤ 4 · default: 1 |
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 |
