OpenAI Build Week
Join a global week of building with Codex
About
OpenAI Build Week is a global hackathon for developers and builders creating with Codex and GPT-5.6. Registration is now open. When submissions open on July 13, we'll share the full challenge details, including tracks, prizes, judges, and resources. You'll then have until July 21 at 5:00 PM PT to create and submit your project. Participate on your own or with a team. Whether you're creating an app, website, agent, game, developer tool, workflow, or something entirely new, use Codex to build something useful, ambitious, or unexpected—show what’s possible when builders and AI agents work side by side. What's next? Meet the community before Build Week begins. Join the #build-week-chat in the OpenAI Discord to connect with other participants. Browse the Participants tab to filter and find teammates
