Image Generation node

Image Generation node card

The Image Generation node creates images from a text prompt using a dedicated image model.

Handles

HandlePurpose
promptThe text prompt describing the image
imagesReference images for image-to-image / conditioning

The node stores no prompt internally — text and references arrive through the handles.

Configuration

  • Model — the image model (e.g. openai/gpt-image-2.5-flare).
  • Size — output dimensions.
  • Aspect ratio — e.g. 16:9, 1:1.
  • Number — 1–4 images.
  • Seed — deterministic output.
  • Qualitylow / medium / high / auto. Defaults to medium for gpt-image models (significantly faster than the provider default).

Example — image-to-image

Wire an Upload File (image) into images, and a Prompt into prompt:

prompt: "Closeup of the subject's face, dramatic lighting"
images: <uploaded photo>

The generated image ({ dataUrl, mime }, or an array when n > 1) becomes the payload for downstream nodes.

Chaining

An Image Generation node’s output can feed another Image Generation node’s images handle — “generate a scene, then a closeup of it.”

Notes

  • The card shows a full-height preview; click to enlarge in a lightbox.
  • Every generation is saved to the node’s artifact history (downloadable).
