Bana ran the 2026 National Youth SW·AI Competition hosted by Hanyang University ERICA. Over four months, from the recruitment call in late March to the results announcement on July 27, more than 2,000 students from over 600 schools across 14 provinces and metropolitan cities took part.
In the pre-training on July 4, students learned AI literacy, prompting, and vibe coding. At the opening ceremony at 14:00 on July 18, 4 SDG themes and 8 specific topics were revealed. Participants built online overnight for 20 hours, with mentor breakout rooms open throughout. Work was submitted by 10:30 on July 19.
Submissions went through three rounds of judging, an AI pre-review, expert scoring, and a final review, and 13 winning teams were selected on July 27. More than 600 teams completed their work, and the entries can be browsed in the Bana gallery.

What Hanyang University ERICA decided was the name and the direction of the competition.
Bana ran four months of the work: nationwide recruiting, pre-training, watching over the overnight build, mentoring, three-stage judging, and the results announcement.
Bana designed it all, from recruiting more than 2,000 students across 14 provinces and metropolitan cities to team assignments and the schedule.
A single Bana dashboard showed how all 2,000 were doing in real time, and we sat through the all-nighter with them.
From AI pre-screening through expert scoring, final review, and the results announcement, we backed the judging process with data.
When the competition ends, every team’s project goes straight to the gallery, and entrants from across the country open each other’s work.
