Inputs (11)
| Name | Type | Default | Description |
|---|---|---|---|
| api_key | STRING | Stability AI API key (sent as 'Authorization: Bearer ...'). | |
| base_url | STRING | https://api.stability.ai/v2beta | Stability v2beta API base URL. Override only for relays/proxies. |
| model | COMBO | stable-image-ultra | 'stable-image-ultra' uses Stable Image Ultra; 'sd3.5-*' uses Stable Diffusion 3.5. |
| prompt | STRING | What you wish to see in the output image. A strong, descriptive prompt that clearly defines elements, colors, and subjects will lead to better results. To control the weight of a given word use the format `(word:weight)`, where `word` is the word you'd like to control the weight of and `weight` is a value between 0 and 1. | |
| aspect_ratio | COMBO | 1:1 | Aspect ratio of generated image. Ignored in image-to-image mode. |
| seed | INT | 00–4294967294 | The random seed used for creating the noise. |
| style_presetopt | COMBO | None | Optional desired style of generated image. 'None' applies no preset. |
| cfg_scaleopt | FLOAT | 4.01–10 | Stable Diffusion 3.5 only: how strictly the diffusion process adheres to the prompt. |
| imageopt | IMAGE | Optional input image for image-to-image generation. | |
| negative_promptopt | STRING | A blurb of text describing what you do not wish to see in the output image. | |
| image_denoiseopt | FLOAT | 0.500–1 | Denoise of input image; 0.0 yields an image identical to input, 1.0 is as if no image was provided. Only used when an image is provided. |
