Overview

This project shows:

• How to connect a Gradio front-end interface to a Comfy UI backend
• Sending workflow data as API requests
• Updating generation parameters dynamically
• Displaying generated images in Gradio
• Adding text and image inputs
• Using a smartphone camera for image inputs

By the end, you'll understand the basics of building a Python API and connecting a user interface with an AI workflow.

Running the Code

To run the code:

1. Clone the repo
2. Install dependencies (pip install requests Pillow gradio numpy)
3. Modify the Comfy UI installation path
4. Open python app.py and modify the INPUT_DIR and OUTPUT_DIR folder path
5. Run python app.py
6. Open the localhost link to view in Gradio interface

The main files:

• app.py - Contains Gradio UI and API logic
• workflow_api.json - Saved Comfy UI workflow
