Luma Text to Image API Node ComfyUI Official Example

This guide explains how to use the Luma Text to Image Partner node in ComfyUI

The Luma Text to Image node allows you to generate high-quality images from text prompts using Luma AI’s advanced technology, capable of creating photorealistic content and artistic style images.

In this guide, we’ll show you how to set up workflows using this node for text-to-image generation.

To use the API nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the API Nodes Overview section of the documentation to understand the specific requirements for using the API nodes.

Portable or self deployed users

Make sure your ComfyUI is updated.

• Download ComfyUI
• Update Guide

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 If you can’t find them in the template, your ComfyUI may be outdated.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

Desktop or Cloud users

• The Desktop is base on ComfyUI stable release, it will auto-update when there is a new Desktop stable release available.
• Cloud will update after ComfyUI stable release.

So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.

Luma Text to Image API Node Workflow

When the Luma Text to Image node is used without any image inputs, it functions as a text-to-image workflow. In this guide, we’ve created examples using style_image and image_luma_ref to showcase Luma AI’s excellent image processing capabilities.

1. Download Workflow Files

The workflow information is included in the metadata of the image below. Download and drag it into ComfyUI to load the workflow.

Please download these images for input:

2. Follow Steps to Run the Workflow

Follow the numbered steps in the image to complete the basic workflow:

1. Upload the reference image in the Load image node
2. Upload the style reference image in the Load image (renamed to styleref) node
3. (Optional) Modify the prompts in the Luma Text to Image node
4. (Optional) Adjust the style_image_weight to control the style reference image’s influence
5. Click the Run button or use the shortcut Ctrl(cmd) + Enter to generate the image
6. After the API returns results, view the generated image in the Save Image node. Images are saved to the ComfyUI/output/ directory

3. Additional Notes

• The node allows up to 4 reference images and character references simultaneously.
• To enable multiple image inputs, right-click on the purple “Bypassed” nodes and set their mode to always
