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.
• ​1:00 AM – 2:45 AM: Deboard at Vyttila, submission checks, showcase review, and finalist shortlisting.
• ​2:45 AM – 4:15 AM: Top 10 lightning demos, judge Q&A, deliberation, and winner announcements.
• ​4:15 AM – 5:00 AM: Photos, media bytes, participant exit, and wrap-up.

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.
