Request body
13 properties · 2 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| prompt* | string | The prompt to generate an image from. | |
| reference_image_url* | string | URL of image to use for inpainting. | |
| 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 |
| num_inference_steps | integer | The number of inference steps to perform. | 1 ≤ n ≤ 50 · default: 20 |
| 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 |
| id_weight | number | The weight of the ID loss. | 0 ≤ n ≤ 1 · default: 1 |
| max_sequence_length | enum | The maximum sequence length for the model. | 128 | 256 | 512 · default: "128" |
| image_size | ImageSize | enum | The size of the generated image. | default: "landscape_4_3" |
| true_cfg | number | The weight of the CFG loss. | 1 ≤ n ≤ 10 · default: 1 |
| negative_prompt | string | The prompt to generate an image from. | default: "" |
| 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 |
| start_step | integer | The number of steps to start the CFG from. | 0 ≤ n ≤ 50 · default: 0 |
Types
1 $defsImageSizeobject
| width | integer | The width of the generated image. | 0 < n ≤ 14142 · default: 512 |
| height | integer | The height of the generated image. | 0 < n ≤ 14142 · default: 512 |
