ComfyUI: Integrating ChatGPT API for Prompt Generation

ComfyUITry it →Watch full video →pixaroma ·

Demo summary

The instructor demonstrates signing into the ComfyUI API and using a ChatGPT node to automatically generate detailed image prompts for local models.

Step-by-step

  1. Click the plus icon to add a new blank workflow in ComfyUI
  2. Double-click the canvas and search for 'chat GPT' to add the API node
  3. Select a model from the OpenAI list within the node settings
  4. Drag a link from the node's string output and add a 'Preview as Text' node
  5. Go to Settings > User and click 'Sign In' to log in with a ComfyUI or Google account
  6. Click 'Purchase Credits' and select an amount (minimum $5) to fund the API usage
  7. Enter your prompt in the ChatGPT node and run the workflow to generate text
  8. Connect the ChatGPT node output to a local model's positive prompt input

Options

  • Select 'ChatGPT Mini' to consume near-zero credits per request
  • Select larger models for higher quality at a cost of 2-8 credits
  • Pay via Link, credit card, or Google Pay
  • Purchase credits as a business

Watch out for

  • API nodes require a stable internet connection to function
  • A minimum purchase of $5 (1,550 credits) is required to start using paid API nodes
  • You have less control over model internals compared to local nodes

Tips

  • Use ChatGPT Mini for testing to save credits as it is significantly cheaper
  • Log in with Google for a faster setup process
  • Refine your prompt instructions (e.g., 'generate a single prompt') to avoid getting multiple suggestions that might break your workflow
  • Use API nodes to save local VRAM and system resources when running heavy models

Highlights

“From the workflow point of view, nothing special is happening. Nodes still connect left to right. Data still flows through cables.”
