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.

promptPositive text promptSTRINGYes-
negative_promptNegative text promptSTRINGYes-
image_typeImage reference type selection (advanced). Required when a reference image is provided.COMBOYes"subject_reference"
"style_reference"
image_fidelityReference intensity for user-uploaded images (default: 0.5, advanced)FLOATYes0.0 - 1.0
human_fidelitySubject reference similarity (default: 0.45, advanced)FLOATYes0.0 - 1.0
model_nameModel selection for image generation (default: “kling-v3”)COMBOYes"kling-v3"

nNumber of generated images (default: 1)INTYes1 - 9
imageOptional reference imageIMAGENo-
seedSeed controls whether the node should re-run; results are non-deterministic regardless of seed (default: 0)INTNo0 - 2147483647
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.
