OpenAI Chat API Node ComfyUI Official Example

This article will introduce how to use OpenAI Chat Partner nodes in ComfyUI to complete conversational functions

OpenAI is a company focused on generative AI, providing powerful conversational capabilities. Currently, ComfyUI has integrated the OpenAI API, allowing you to directly use the related nodes in ComfyUI to complete conversational functions.

In this guide, we will walk you through completing the corresponding conversational functionality.

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 If you can’t find them in the template, your ComfyUI may be outdated.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

OpenAI Chat Workflow

2. Complete the Workflow Execution Step by Step

In the corresponding template, we have built a role setting for analyzing prompt generation.

You can refer to the numbers in the image to complete the basic text-to-image workflow execution:

1. In the Load Image node, load the image you need AI to interpret
2. (Optional) If needed, you can modify the settings in OpenAI Chat Advanced Options to have AI execute specific tasks
3. In the OpenAI Chat node, you can modify Prompt to set the conversation prompt, or modify model to select different models
4. Click the Run button, or use the shortcut Ctrl(cmd) + Enter to execute the conversation.
5. After waiting for the API to return results, you can view the corresponding AI returned content in the Preview Any node.

3. Additional Notes

• Currently, the file input node OpenAI Chat Input Files requires files to be uploaded to the ComfyUI/input/ directory first. This node is being improved, and we will modify the template after updates
• The workflow provides an example using Batch Images for input. If you have multiple images that need AI interpretation, you can refer to the step diagram and use right-click to set the corresponding node mode to Always to enable it
