In this video, I show you how to build a Python API to connect Gradio and Comfy UI for generating AI images. This is a great project to make your own frontend.

In this programming tutorial, I show you step-by-step how to build a Python API to connect Gradio and Comfy UI. We start with a simple example that generates an image on button click. Then we add text and image inputs to control image generation parameters.

I appreciate if you can like and share the video if it was helpful.
