Luma Text to Image API Node ComfyUI Official Example

This guide explains how to use the Luma Text to Image API 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.

If you find missing nodes when loading the workflow file below, it may be due to the following situations:

1. You are not using the latest Development (Nightly) version of ComfyUI.
2. You are using the Stable (Release) version or Desktop version of ComfyUI (which does not include the latest feature updates).
3. You are using the latest Commit version of ComfyUI, but some nodes failed to import during startup.

Please make sure you have successfully updated ComfyUI to the latest Development (Nightly) version. See: How to Update ComfyUI section to learn how to update ComfyUI.

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
