ComfyUI: Load a text-to-image workflow and download missing models

ComfyUITry it →Watch full video →@KevinStratvert ·

Demo summary

The user demonstrates how to load a default text-to-image template in ComfyUI and use the 'show missing models' feature to download required AI checkpoints.

Step-by-step

  1. Select the Text to Image option from the getting started section
  2. Click on Show missing models in the top right-hand corner
  3. Review the required model list provided by ComfyUI
  4. Click on Download all to install the necessary checkpoints
  5. Monitor the download progress at the top of the interface
  6. Zoom in on the workflow nodes once the download is complete

Watch out for

  • The workflow cannot generate images until the specific required models are downloaded and installed

Tips

  • Think of ComfyUI as the application framework, while the model is the engine that actually creates the image
