Kochi is building after dark. 🌙🚇
Welcome to Codex Nightline, the World's first AI build sprint inside a moving metro system.
​100 curated builders will board at Vyttila Metro Station, build through a moving metro round trip using Codex, and present what they made before sunrise.
​This is not a normal hackathon. It is one train, one night, one intense solo build sprint.
Venue / Mobility Partner: Kochi Metro Rail Limited (KMRL)
Starting & Ending Point: Vyttila Metro Station
Format: Solo AI build sprint
Event Flow
- ​9:30 PM – 11:00 PM: Reporting, check-in, briefing, opening, security, and boarding at Vyttila.
- ​11:00 PM – 1:00 AM: Exclusive Metro AI Sprint. Participants build onboard during the metro round trip using Codex.

Important Note
​👤 This is a solo build sprint, not a team event. Participants will build and compete individually.
​Ideas can be prepared beforehand, but implementation starts only after the official sprint begins.
