Kling Image Generation Node generates images from text prompts with the option to use a reference image for guidance. It creates one or more images based on your text description and reference settings, then returns the generated images as output.

Inputs

Parameter	Data Type	Required	Range	Description
prompt	STRING	Yes	-	Positive text prompt
negative_prompt	STRING	Yes	-	Negative text prompt
image_type	COMBO	Yes	"subject_reference" "style_reference"	Image reference type selection (advanced). Required when a reference image is provided.
image_fidelity	FLOAT	Yes	0.0 - 1.0	Reference intensity for user-uploaded images (default: 0.5, advanced)
human_fidelity	FLOAT	Yes	0.0 - 1.0	Subject reference similarity (default: 0.45, advanced)
model_name	COMBO	Yes	"kling-v3" "kling-v2" "kling-v1-5"	Model selection for image generation (default: “kling-v3”)
aspect_ratio	COMBO	Yes	"16:9" "9:16" "1:1" "4:3" "3:4" "21:9" "9:21"	Aspect ratio for generated images (default: “16:9”)
n	INT	Yes	1 - 9	Number of generated images (default: 1)
image	IMAGE	No	-	Optional reference image
seed	INT	No	0 - 2147483647	Seed controls whether the node should re-run; results are non-deterministic regardless of seed (default: 0)

Parameter Constraints:

• The image parameter is optional. When a reference image is provided, the image_type parameter must be set to either "subject_reference" or "style_reference".
• When no reference image is provided, the image_type, image_fidelity, and human_fidelity parameters are not used.
• Prompt and negative prompt have a maximum length of 500 characters.
• The seed parameter is optional and does not guarantee deterministic results.

Outputs

Output Name	Data Type	Description
output	IMAGE	Generated image(s) based on the input parameters
