Codex Community Build Hackathon – Bangalore

​Join us for a focused morning of building with Codex.

​Build something new, improve an existing project, or experiment with agentic software-development workflows using Codex. Explore parallel tasks, Skills, worktrees, and other ways to build with greater speed and ambition.

​How it works

​Participants may work individually or in teams of up to four members.

​You could:

• ​Start a new project from scratch
• Extend an existing or open-source project
• Prototype a developer tool or agent workflow
• Experiment with Codex Skills and parallel tasks
• Improve an existing project using Codex

​Suggested build directions

​Projects may explore areas such as:

• ​Agentic Coding: Developer tools and workflows that maximise leverage from Codex
• ​AI-Native Developer Experience: Interfaces and workflows designed around coding agents
• Domain Agents: Agents designed for specific industries or real-world constraints
• Multimodal Applications: Applications that work across text, images, audio, or other modalities
• Agent Evaluation: Tools for measuring, debugging, and improving agent performance
• Open Source: Contributions or improvements to existing open-source projects

​These are suggestions rather than restrictions. Participants are welcome to build in any direction where Codex plays a meaningful role.
