Ideogram 4.0 is the latest text-to-image model from Ideogram, offering superior photorealistic quality, accurate text rendering, and precise style control. You can use either plain natural language or structured JSON prompts for fine-grained control over layout, colors, and in-image text.
To use the Partner Nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the Partner Nodes Overview section of the documentation to understand the specific requirements for using the Partner Nodes.
Make sure your ComfyUI is updated.Workflows in this guide can be found in the Workflow Templates. If you can’t find them in the template, your ComfyUI may be outdated. (Desktop version’s update will delay sometime)If nodes are missing when loading a workflow, possible reasons:
  1. You are not using the latest ComfyUI version (Nightly version)
  2. Some nodes failed to import at startup

​
Prompt Format

The Ideogram V4 node supports two prompt formats:
  1. Natural Language — Simple and intuitive, best for quick ideas.
  2. Structured JSON — Offers fine-grained control over style palette, element placement (bbox), and literal text rendering in the image. Recommended for poster-like compositions.
The default workflow example uses a structured JSON prompt that includes:
  • high_level_description — Overall scene description
  • style_description — Aesthetic, lighting, medium, color palette
  • compositional_deconstruction — Per-element bounding boxes, descriptions, and color palettes

​
Workflow Steps

  1. Download and drag the workflow file into ComfyUI
  2. The Ideogram V4 node already contains a default structured JSON prompt — you can modify it or write plain natural language
  3. Click Run or use shortcut Ctrl(cmd) + Enter to generate the image
  4. After the API returns results, view the generated image in the Save Image node. Images are saved to the ComfyUI/output/ directory

​
Using the JSON Prompt Builder (Optional)

The workflow includes a built-in Gemini node (Gemini 3.1 Pro) to help you build structured JSON prompts:
  1. Describe your idea in the Gemini node’s user prompt field
  2. The model will generate a schema-matching JSON prompt
  3. Connect the STRING output to the Ideogram V4 node’s prompt input
  4. Run the workflow

​
Additional Notes

  • Negative prompts are not needed — The Ideogram 4.0 model uses asymmetric classifier-free guidance, where the unconditional pass drops text tokens, rather than requiring a separate negative prompt string.
  • Model-assisted prompt building — Consider using the Ideogram 4 Prompt Builder (KJNodes) for visual control over prompt construction on ComfyUI.
