Join us for a day of building with Codex together with our friends at GrowthX. We’re bringing together 100 of the most ambitious builders — developers who already use AI coding tools daily and are comfortable shipping production-grade code. This is not an introductory workshop. Expect to move fast. Build something new from scratch or push an existing open-source project further with Codex. Spin up subagents & parallel tasks, use Plugins, and leverage worktrees to operate at a higher level of velocity and ambition. Each builder will receive API credits and 1 month of ChatGPT Pro. What will you build? Registration Details Attendance is capped (maximum of 4 members per team) to keep the room high-signal & deeply hands-on. Please note that due to venue capacity, registration is subject to approval. Kindly complete the registration form with your accurate details, as incomplete or inaccurate submissions will not be admitted. Selected and waitlisted participants will be notified by 10 April. Note: If you intend to participate as a team, all members must register individually and receive approval separately. Please apply by 7 April, 12noon IST Build Directions No fixed theme — just ambitious builds. Focus on ideas that wouldn’t be possible without Codex. Build with Codex, or on top of it (App Server, SDK, or your own abstractions). If any of these directions resonate — apply: 🔹 Agentic Coding — Build developer tools that maximise leverage from Codex as an AI coding agent 🔹 UX for Agentic Applications — Design AI-native interaction patterns and product flows 🔹 Multimodal Intelligence — Create systems that reason across text, voice, and vision 🔹 Domain Agents — Go deep on vertical agents with real-world constraints 🔹 Building Evals — Build tooling to measure, debug, and improve agent performance. 🥇 Prizes To be revealed! Prize pool of over 100k USD in credits & subscriptions will be available.
