What it is

Anyone can talk about AI. Fewer can ship it.

Prove you have what it takes and take home OpenAI Codex credits.

The Codex × UX+AI Hackathon is an in-person build for designers, developers, product people, students, founders, and anyone ready to turn an idea into a working prototype.

Apply with the problem you want to solve and what you plan to make. We’ll review every application and email the people who are accepted. A submission is not yet a confirmed spot—watch your inbox.
