Welcome to Pune's first OpenAI Codex Community Hackathon.

We are moving past the chat interface. This is about architecting the future of software by shifting the focus from writing code to orchestrating agents. Whether you are building a new autonomous tool or accelerating an existing project, this is where the shipping happens.

​Build something new from scratch or push an existing project further using Codex. Run parallel tasks, experiment with Skills, and use worktrees to operate at a higher level of speed and ambition.

You can participate solo or in teams of up to 4 members maximum. If you're participating as a team, every team member has to register separately.

​​​​Exploration Over Experience

​This event is designed for builders, not just developers. If you have never used Codex (or any agentic coding tools), do not worry. We are all exploring this frontier together. You will build alongside Codex Ambassadors and a room full of peers who are just as curious about the future of software as you are.

​​​​Build Directions

​If any of these ideas excite you, we want you in the room:

• Agentic Coding: Build developer tools that maximize leverage from Codex as an AI coding agent.
• UX for Agentic Applications: Design AI-native interfaces and workflows for agent-driven software.
• Multimodal Intelligence: Create applications that reason across multiple modalities.
• Domain Agents: Build vertical agents that operate within real-world constraints.
• Building Evals: Develop tools to measure, debug, and improve agent performance.

​​​​Prizes

​$100k+ prize pool of credits and subscriptions. We are excited to offer massive support for the winning teams:
