What is an Image Node?

Image Node
The Image node allows you to generate visual content from text prompts using AI image generation models such as OpenAI’s DALL·E 3 or Stable Diffusion. Use this node to turn descriptions into visuals. Ideal for creative tools, content generation, or enhancing user engagement with dynamic imagery. Common applications include:
  • Illustrating chatbot responses
  • Creating product mockups or concept art
  • Generating visual assets on-the-fly for user interfaces

How to use it?

To use the Image node:
  • Input: Accepts a text string (prompt), often from a user or LLM node.
  • Output: Returns a generated image that can be previewed or used downstream.
The model processes the prompt and returns a generated image in the specified size and style.
