OpenAI and Sea are both building at the frontier of AI - OpenAI through the models and tools that define what's possible, Sea through the products and systems serving hundreds of millions of people across Southeast Asia and beyond. Together, we're investing in Southeast Asia's AI ecosystem - giving the region's best builders a space to push limits and forge what comes next. The regional Sea x OpenAI Codex Hackathon is where it starts. Singapore is the first stop.
One day. Build something real.
This event is for builders who are already comfortable using AI coding tools and shipping production-grade code - not an introductory workshop for those just getting started with AI.
We're bringing together serious builders - engineers and founders who are already building with AI and want to push further. Expect to move fast, make sharp decisions, and come with a problem worth solving.
