Request body
12 properties · 2 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| image_url* | string | The image URL to generate an image from. Needs to match the dimensions of the mask. | |
| prompt* | string | The prompt to generate an image from. | |
| 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 |
| 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 |
| 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: "" |
| num_images | integer | The number of images to generate. | 1 ≤ n ≤ 4 · default: 1 |
| scale | number | The scale of the subject image. Higher values will make the subject image more prominent in the generated image. | 0 ≤ n ≤ 2 · default: 1 |
| image_size | ImageSize | enum | The size of the generated image. | default: "square_hd" |
| num_inference_steps | integer | The number of inference steps to perform. | 1 ≤ n ≤ 50 · default: 28 |
| output_format | enum | The format of the generated image. | jpeg | png · default: "jpeg" |
| 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: 3.5 |
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 |
