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	Data Type	Required	Range	Description
prompt	STRING	Yes	-	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.
aspect_ratio	COMBO	Yes	Multiple options available	Aspect ratio of generated image.
style_preset	COMBO	No	Multiple options available	Optional desired style of generated image.
seed	INT	Yes	0-4294967294	The random seed used for creating the noise.
image	IMAGE	No	-	Optional input image.
negative_prompt	STRING	No	-	A blurb of text describing what you do not wish to see in the output image. This is an advanced feature.
image_denoise	FLOAT	No	0.0-1.0	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

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

Outputs

Output Name	Data Type	Description
output	IMAGE	The generated image based on the input parameters.
