Request body
11 properties · 1 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| prompt* | string | The prompt to use for generating the image. Be as descriptive as possible for best results. | |
| first_stage_steps | integer | Number of steps to run the first stage for. | 4 ≤ n ≤ 40 · default: 20 |
| enable_safety_checker | boolean | If set to false, the safety checker will be disabled. Disabling it requires account authorization; unauthorized requests are always checked, and images flagged as unsafe are returned as black images. | default: true |
| second_stage_steps | integer | Number of steps to run the second stage for. | 4 ≤ n ≤ 24 · default: 10 |
| 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: "" |
| image_size | ImageSize | enum | The size of the generated image. | default: "square_hd" |
| num_images | integer | The number of images to generate. | 1 ≤ n ≤ 4 · default: 1 |
| second_stage_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: 0 |
| 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 |
| 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 |
| seed | integer | The same seed and the same prompt given to the same version of Stable Cascade will output the same image every time. | nullable |
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 |
