This is an introductory Vibe Coding workshop hosted as part of ChatGPT Labs @ Waseda, where you will use Codex (OpenAI's AI agent for coding tasks) to build your own software by simply describing what you want to create. During the session, we will walk you through the setup of Codex and everything else you need, followed by free time for you to bring your vision to life. We will round off the session with demos from participants who would like to share their creations with the rest. Whether you're completely new to programming or already curious about AI, beginners are more than welcome! Participation is prioritized for Waseda University students; however, if spots remain, students from other universities are welcome to attend as well.
