OpenAI Codex - Fast Hacks in Tokyo
[Tokyo] Fast Hacks - Hack Night - with OpenAI Codex
An evening for builders who show instead of tell.
Fast Hack Night is a focused, high-tempo gathering of makers putting real projects on display. No hype, no pitches, just rapid experimentation and working demos.
Schedule
5:00 PM - Doors Open
5:30 PM - Introduction
6:00 PM - Building Begins
8:00 PM - Demos Begin
9:00 PM - Event Ends
You and your AI Agents get two hours to build, then everyone with working demos present what they made. Come with a project in mind, team up with someone on the spot, or just show up to watch, learn, and network.
Food and drinks are on us, and the best demos take home prizes!
Come to share what you’ve been working on.
Come to see what others are quietly creating.
Leave inspired.
