Request body
13 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. | |
| 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: true |
| 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: 1.5 |
| format | enum | The format of the generated image. | jpeg | png · default: "jpeg" |
| num_images | integer | The number of images to generate. | 1 ≤ n ≤ 8 · default: 1 |
| safety_checker_version | enum | The version of the safety checker to use. v1 is the default CompVis safety checker. v2 uses a custom ViT model. | v1 | v2 · default: "v1" |
| seed | integer | The same seed and the same prompt given to the same version of Stable Diffusion will output the same image every time. | nullable |
| enable_prompt_expansion | boolean | If set to true, the prompt will be expanded with additional prompts. | default: false |
| request_id | string | An id bound to a request, can be used with response to identify the request itself. | default: "" |
| num_inference_steps | integer | The number of inference steps to perform. | 1 ≤ n ≤ 32 · default: 6 |
| 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" |
| enable_safety_checker | boolean | If set to true, the safety checker will be enabled. | default: true |
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 |
