Luma Image to Image Partner Nodes ComfyUI Official Example

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

The Luma Image to Image node allows you to modify existing images based on text prompts using Luma AI technology, while preserving certain features and structures from the original image.

What Luma Image to Image is good at

• Prompt-driven image editing: Modifies existing images based on text prompts while preserving certain features and structures from the original
• Changing objects and shapes: The node works well for changing objects and shapes, though it may not be ideal for color changes
• Adjustable input influence: The image_weight parameter controls how strongly the input image shapes the result, with lower values staying closer to the original

Example outputs

Results at different image_weight values, showing how strongly the input image influences the generated output:

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.
