Join **OpenAI and top developers** for a day of hands-on building with **Codex, our AI coding agent.** Create a compelling app that showcases how Codex accelerates designing, building and shipping software or use it to accelerate on an existing project. With the new **Codex app**, you can kick off parallel tasks, leverage skills and worktrees to bring more ideas to life. You'll build alongside the OpenAI team and pitch your project to our judges for a chance to be featured in an exclusive demo showcase.

This event is designed for developers with a baseline of technical knowledge. No prior experience using Codex is required.

The top three teams will win **$90,000 in credits plus a year of ChatGPT Pro.**

Judges include **Greg Brockman**, **Thibault Sottiaux**, **Sonya Huang**, **Lenny Rachitsky**, and **Peter Steinberger**.

*Note: This is a fully in-person event in San Francisco. Space is limited. Maximum team size is four. All attendees must submit an application for approval.*
