ComfyUI Extension: ComfyUI-Prompt-Combinator

ComfyUI-Prompt-Combinator Introduction

The ComfyUI-Prompt-Combinator is an extension designed to enhance your creative workflow by generating all possible combinations of prompts from multiple lists of strings. This tool is particularly useful for AI artists who want to explore a wide range of creative possibilities without manually crafting each prompt combination. By automating the combination process, the ComfyUI-Prompt-Combinator saves time and effort, allowing you to focus more on the artistic aspects of your work.

How ComfyUI-Prompt-Combinator Works

The ComfyUI-Prompt-Combinator operates on a simple yet powerful principle: it takes multiple lists of strings (prompts) and generates every possible combination of these strings. Imagine you have three lists of words or phrases. The extension will mix and match each item from the lists to create a comprehensive set of unique prompts.

For example, if you have:

• List 1: "a cat", "a dog"
• List 2: "with pointy ears", "with fluffy tail", "with two heads"
• List 3: "cute", "scary" The extension will generate combinations like:
• "a cat with pointy ears cute"
• "a cat with pointy ears scary"
• "a dog with fluffy tail cute"
• "a dog with two heads scary" This combinatorial approach ensures that you explore all potential prompt variations, which can be particularly useful for generating diverse AI-generated art.

ComfyUI-Prompt-Combinator Features

Prompt Combinator Node

This is the core feature that generates all possible combinations of prompts from your input lists. You can input up to 8 different lists, and the node will output a comprehensive list of combined prompts.

Prompt Combinator Merger Node

This feature allows you to merge the outputs of two different Prompt Combinator nodes. It is useful when you want to combine complex sets of prompts generated from different sources.

Prompt Combinator Export Gallery Node

This node generates an HTML gallery to navigate the output of the Prompt Combinator. It visually displays the prompts alongside their corresponding images, making it easier to review and select the best combinations. You can see an example of the gallery here and a gallery with all embedded in a single HTML here.

Pick Random Prompt from Prompt Combinator Node

This feature picks a single random prompt from the output of the Prompt Combinator. It is useful when you want to quickly test a random combination without going through the entire list.

ComfyUI-Prompt-Combinator Models

The extension does not include different models but rather focuses on the combinatorial generation of prompts. The nodes provided are designed to work together to enhance your prompt generation process.

Troubleshooting ComfyUI-Prompt-Combinator

Common Issues and Solutions

Issue: No Output Generated

• Solution: Ensure that all input lists are correctly populated and that there are no empty strings. Check the node connections to make sure they are properly linked.

Issue: HTML Gallery Not Displaying Correctly

• Solution: Verify that the HTML file is correctly generated and that all necessary files (images, CSS) are in the same directory. Try opening the HTML file in a different browser.

Issue: Random Prompt Selection Not Working

• Solution: Make sure the Pick Random Prompt from Prompt Combinator node is correctly connected to the output of the Prompt Combinator node. Check for any errors in the node configuration.

Frequently Asked Questions

Q: Can I use more than 8 input lists?

• A: Currently, the extension supports up to 8 input lists. For more complex combinations, consider merging outputs from multiple Prompt Combinator nodes. Q: How do I identify which inputs were used in the generated prompts?
• A: Prepend the prompts with identifiers (e.g., "cat@a cat") to easily track which inputs were used in each combination.
