Generates images synchronously based on prompt and aspect ratio. This node creates images using text descriptions and allows you to control the image dimensions and style through various reference inputs.

Inputs

Parameter	Data Type	Required	Range	Description
`prompt`	STRING	Yes	-	Prompt for the image generation (default: empty string)
`model`	COMBO	Yes	Multiple options available	Model selection for image generation
`aspect_ratio`	COMBO	Yes	Multiple options available	Aspect ratio for the generated image (default: 16:9 ratio)
`seed`	INT	Yes	0 to 18446744073709551615	Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0)
`style_image_weight`	FLOAT	No	0.0 to 1.0	Weight of style image. Ignored if no style_image provided (default: 1.0)
`image_luma_ref`	LUMA_REF	No	-	Luma Reference node connection to influence generation with input images; up to 4 images can be considered
`style_image`	IMAGE	No	-	Style reference image; only 1 image will be used
`character_image`	IMAGE	No	-	Character reference images; can be a batch of multiple, up to 4 images can be considered

Parameter Constraints:

The image_luma_ref parameter can accept up to 4 reference images
The character_image parameter can accept up to 4 character reference images
The style_image parameter accepts only 1 style reference image
The style_image_weight parameter is only used when style_image is provided
