Request body
16 properties · 2 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| image_url* | string | URL of the input image. | |
| prompt* | string | The text prompt to guide image generation. | |
| enable_prompt_expansion | boolean | Whether to enable prompt expansion. This will use a large language model to expand the prompt with additional details while maintaining the original meaning. | default: false |
| enable_safety_checker | boolean | If set to true, input data will be checked for safety before processing. Disabling it requires account authorization; unauthorized requests are always checked. | default: false |
| negative_prompt | string | Negative prompt for video generation. | default: "" |
| aspect_ratio | enum | Aspect ratio of the generated image. If 'auto', the aspect ratio will be determined automatically based on the input image. | auto | 16:9 | 9:16 | 1:1 · default: "auto" |
| acceleration | enum | Acceleration level to use. The more acceleration, the faster the generation, but with lower quality. The recommended value is 'regular'. | none | regular · default: "regular" |
| shift | number | 1 ≤ n ≤ 10 · default: 2 | |
| image_size | ImageSize | enum | nullable | |
| enable_output_safety_checker | boolean | If set to true, output video will be checked for safety after generation. | default: false |
| num_inference_steps | integer | Number of inference steps for sampling. Higher values give better quality but take longer. | 2 ≤ n ≤ 40 · default: 27 |
| seed | integer | Random seed for reproducibility. If None, a random seed is chosen. | nullable |
| strength | number | Denoising strength. 1.0 = fully remake; 0.0 = preserve original. | 0 ≤ n ≤ 1 · default: 0.5 |
| guidance_scale_2 | number | Guidance scale for the second stage of the model. This is used to control the adherence to the prompt in the second stage of the model. | 1 ≤ n ≤ 10 · default: 4 |
| image_format | enum | The format of the output image. | png | jpeg · default: "jpeg" |
| guidance_scale | number | Classifier-free guidance scale. | 1 ≤ n ≤ 10 · 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 |
