Join DevDay Exchange Community Hackathon: New Delhi

A full-day builder sprint with Codex — OpenAI’s coding agent that helps developers build and ship faster.

Following the ideas & announcements from OpenAI DevDay we’re bringing the Delhi NCR builder community together again to experiment, build, and ship with Codex.

The goal is simple: build something real in one day.

What to Expect

We’ll start with a DevDay special recap, followed by a short Codex session covering practical workflows and useful patterns for building with coding agents.

After that, most of the day is yours to build.

You can:

  • Start a new project from scratch

  • Build an AI-native product

  • Experiment with agentic developer workflows

  • Create tools around Codex, agents, evals, automation, or productivity

  • Explore something completely different if you can build and demo it

Mentors will be available during the build sprint to help teams with technical, product, and demo-related questions.

Solo or Team?

You can participate:

  • Solo

  • As a team

  • Or come solo and form a team at the hackathon

Maximum team size: 3 members

If you already have a team, every team member must register individually and receive approval separately.

If you're under 18, please bring permission from your parent/guardian to attend. Parents/guardians will not be permitted inside unless separately registered and approved.

We’ll also help interested solo participants meet other builders during the initial team-formation window.

Who This Is For

This event is best suited for:

  • Developers and AI builders

  • Working professionals

  • Startup founders

  • College Students

  • School Students

  • Anyone with enthusiasm or strong project/building experience

No prior Codex experience is required, but participants should be comfortable building software and must bring their own laptop.

Have team diversity for faster approvals!
