OpenAI Codex Hackathon - Singapore
Join us for a day of building with Codex together with our friends at Lorong AI and 65Labs.
This event is designed for developers who already use AI coding tools daily and are comfortable shipping production-grade code. No prior experience with Codex is required, but this is not an introductory workshop. Expect to hit the ground running fast.
Build something new from scratch or push an existing open-source project further with Codex. Spin up parallel tasks, use Skills, and leverage worktrees to operate at a higher level of velocity and ambition.
Attendance is capped (maximum of 4 members per team) to keep the room high-signal and deeply hands-on.
Please note that due to venue capacity, registration is subject to approval. Kindly complete the registration form with your accurate details, as incomplete or inaccurate submissions may not be admitted. If you intend to participate as a team, all members must register individually and receive approval separately.
