Codex Community Kochi Kochi Metro 100 Solo Builders
Codex Nightline
The world’s first AI Build sprint inside a moving Metro system.
On 18 July 2026, 100 builders took over an after-hours Kochi Metro train for two hours of building with AI.
The route
becomes the timer.
Four stations, one loop. Your progress moves with the train from Vyttila to Aluva to Thrippunithura and back.
Tonight, we build.
The sprint happens on the train. The showcase, judging, and wrap-up continue at Vyttila after deboarding.
