Overnight AI challenge saw 60 participants tackle a series of challenges using OpenAI Codex, with Kay Hng Quek taking the top prize
SINGAPORE – Media OutReach Newswire – 26 October 2026 – Coupang, a Seattle-based technology company that serves customers in 190 countries and territories, co-hosted an overnight AI hackathon, AI Grand Prix Singapore 2026 (“AI Grand Prix“) with OpenAI. It was presented by Elev8, with Carousell Group as venue partner.
Held from 24 to 25 October 2026 at Carousell Campus, the overnight AI Grand Prix brought together 60 participants, selected from a pool of 150 applicants, to tackle a series of challenges that tested their technical skills, creativity and ability to solve problems under pressure. All participants competed in individual challenges and formed 14 teams for the group challenge. Engagement remained strong through the night, with participants continuing to work on their solutions into the early hours.
From Challenge to Working Solution
Unlike a traditional hackathon centred on a single problem statement, the AI Grand Prix was a multi-challenge competition, requiring them to adapt their approach as the competition progressed. Using OpenAI Codex, participants were tasked with three distinct challenges: Game Hack, which focused on developing creative AI-powered games; Spot the Mismatch, a technical challenge to identify discrepancies in AI-generated product descriptions, images and prices; and Group Hack, in which 14 teams developed AI-powered shopping experiences and solutions. Performance across the challenges was assessed collectively to determine the overall rankings.
Taking the top spot was Kay Hng Quek, who demonstrated strong, consistent problem-solving skills across different technical challenges. He received the Champion’s Builder Kit, a special first-place award comprising a Mac mini, DJI Mic 3 and Elgato Stream Deck Plus, designed to support continued experimentation and creation as an AI builder.
A total of US$13,000 in OpenAI API credits was shared among the winners and OpenAI subscription benefits were also provided to all participants, alongside unlimited Codex usage resets during the event to encourage experimentation with different ideas and approaches. The top 10 participants are scheduled to attend an exclusive networking dinner on 26 October with leadership and technical representatives from Coupang and OpenAI, offering an opportunity to exchange ideas and experiences in building with AI.
“AI Grand Prix was an incredible opportunity to push myself beyond my comfort zone and explore what’s possible with AI. The variety of challenges encouraged us to think creatively, adapt quickly and approach problems from different perspectives. What made the experience even more rewarding was being surrounded by talented, passionate builders who shared ideas and inspired one another. I’m grateful to have been part of such an exciting community, and especially for Jerel, my cofounder, who brings out the best in me,” said Kay Hng Quek, overall champion of AI Grand Prix Singapore 2026.
“Technology and innovation are at the heart of how we create better experiences for our customers, and we see tremendous potential for AI to further transform the future of commerce. Singapore is home to an exciting community of engineers and researchers, and we are thrilled to co-host this event with OpenAI to provide a platform for them to come together, experiment and innovate with AI,” said Xin Fu, VP of Engineering at Coupang.
Derrick Choi, Head of Applied AI, Codex (APAC) at OpenAI, said, “AI is changing how software is built, giving developers new ways to accelerate the journey from concept to product. The AI Grand Prix highlighted the breadth of Singapore’s developer community. It was a great opportunity to give builders a chance to try different approaches with Codex and explore how they could use it to tackle real-world problems.”
The AI Grand Prix marks Coupang’s first event with OpenAI and underscores its continued investment in building the future of commerce with AI, while leveraging Singapore’s position at the heart of Southeast Asia’s technology ecosystem.
