StabilityStableImageUltraNode - ComfyUI Built-in Node Documentation

Generates images synchronously based on prompt and resolution. This node creates images using Stability AI’s Stable Image Ultra model, processing your text prompt and generating a corresponding image with the specified aspect ratio and style.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	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. For example: `The sky was a crisp (blue:0.3) and (green:0.8)` would convey a sky that was blue and green, but more green than blue.	STRING	Yes	-
`aspect_ratio`	Aspect ratio of generated image (default: “1:1”).	COMBO	Yes	`"1:1"` `"16:9"` `"21:9"` `"2:3"` `"3:2"` `"4:5"` `"5:4"` `"9:16"` `"9:21"`
`style_preset`	Optional desired style of generated image. Select “None” to not apply any style preset.	COMBO	No	`"3d-model"` `"analog-film"` `"anime"` `"cinematic"` `"comic-book"` `"digital-art"` `"enhance"` `"fantasy-art"` `"isometric"` `"line-art"` `"low-poly"` `"modeling-compound"` `"neon-punk"` `"origami"` `"photographic"` `"pixel-art"` `"tile-texture"`
`seed`	The random seed used for creating the noise.	INT	Yes	0 - 4294967294
`image`	Optional input image for image-to-image generation.	IMAGE	No	-
`negative_prompt`	A blurb of text describing what you do not wish to see in the output image. This is an advanced feature.	STRING	No	-
`image_denoise`	Denoise of input image; 0.0 yields image identical to input, 1.0 is as if no image was provided at all (default: 0.5).	FLOAT	No	0.0 - 1.0

Note: When an input image is not provided, the image_denoise parameter is automatically disabled and ignored.

Outputs
