Create your own App: AI-Powered Image Generator App Using Python &Tkinter

Duration: Half Day (3 Hours)

Overview

This practical workshop introduces Python developers to integrating OpenAI's Image Generation API into desktop applications.

Delegates will build a complete AI-powered desktop application using Python and Tkinter that enables users to enter an image prompt or select from predefined topics, generate images using OpenAI, preview the generated image within the application, and save the results locally.

The workshop focuses on practical application development techniques that can be applied immediately to AI-enabled business applications.
