GPT-5 Startup Hackathon NYC

GPT-5 and Codex are coming to NYC! We’re looking for early startup teams to come build applications powered by GPT-5 with Codex as your collaborator.

With the release of GPT-5-Codex—a version of GPT‑5 further optimized for agentic coding in Codex, your team can now build faster and smarter. GPT-5-Codex adapts its reasoning time to each task and can independently review, test, and improve your code, making it the ultimate partner for your weekend build.

Gain insights from the OpenAI team, meet fellow founders, and show us what you can ship in one weekend. Live demo for a panel of VC judges and win $50k in credits to accelerate your startup.

Applications reviewed on a rolling basis & space is limited. Maximum team size of four. Every team member must apply & be approved to attend!

Please note: this event is fully in person in New York City.
