OpenAI Build Week Community Buildathon - Manila

Join us for OpenAI Build Week Manila, a one-day Buildathon for people who want to get hands-on with the latest changes across ChatGPT and Codex, including the new GPT-5.6 family of models and ChatGPT-Live-1. ⚡ This is a chance to learn what is newly possible, meet other serious builders, and turn that momentum into a working prototype. We will begin with a practical Codex kickoff, then spend the day building, getting feedback, and showing what we made. This is not just a meetup or a talk. The goal is simple: build something real with Codex. ☀️ What to Expect We will start with a practical Codex session, then move straight into team formation and build time. You can start from scratch, improve something you already have, make a developer tool, prototype an AI-native product, or explore a workflow that makes people more effective. Teams will submit a working project, demo it live, and receive feedback from judges. 🧑‍💻 Who This Is For This Buildathon is for: No prior Codex experience is required, but you should be ready to build, bring your own laptop and charger, and stay for the full event. You are welcome to build in any direction. A few starting points: agentic coding tools and workflows that give developers more leverage with Codex; AI-native products where AI is central to the experience; developer tools that help people build, test, debug, document, or ship; evals and reliability tooling that measures and improves agent performance; or domain agents that solve real problems for a specific community or industry. 🏆 Prizes & Rewards Codex credits & API credits will be distributed. Prize winners will receive: 📍 Event Details Date: Saturday, July 18, 2026Time: 9:00 AM-5:00 PMVenue: Leong Hall, Ateneo de Manila University 📅 Agenda 8:00-9:00 AM: Registration, breakfast, and team formation9:00-9:45 AM: Welcome, Codex briefing, and Buildathon kickoff9:25 AM-12:00 PM: Build Sprint 112:00-1:00 PM: Lunch1:00-2:45 PM: Build Sprint 2 and mentor support2:45-3:00 PM: Submission and demo setup3:00-4:00 PM: Demos and judging4:00-4:15 PM: Awards4:15-5:00 PM: Closing and community time 📝 Registration Capacity is limited, and registration is subject to approval.
