OpenAI Build Week

Requirements

What to build

Create a project using Codex with GPT 5.6. Whether it's an app, agent, website, game, workflow, or something entirely new, your project should fit into one of the following tracks: 

• Apps for your life

  • Consumer apps for everyday life — from productivity and creativity to home, family, travel, health, and personal finance.

• Work and productivity

  • Tools that make teams faster or more effective, from workflow automation and customer support to analytics, sales, and back-office operations.

• Developer tools 

  • Tools for developers, including testing, DevOps, agentic workflows, and security.

• Education

  • Projects that specifically push forward AI for education - either helping students, teachers, or educational organizations.

 

What to submit

• A working project. Build something with Codex using GPT-5.6 that meets the challenge requirements. 

• A category. Pick the category that fits best.

• A project description. Tell us what you created and how it works. 

• A demo video.  Upload a <3-minute public YouTube video showing your project working, audio covering how you used Codex AND GPT-5.6 

• Provide a URL to your code repository for judging and testing. The repository must be either public (with relevant licensing) or private and shared with testing@devpost.com and build-week-event@openai.com.

• Include a README with setup instructions, sample data (if needed), and clear guidance for running your project

• Make sure to highlight where Codex accelerated your workflow, where key decisions were made and how GPT-5.6 and Codex were used. This is an important part of how judges evaluate technical implementation and quality of the idea.

• /feedback Codex Session ID where the majority of the core functionality where you built your Project, get the /feedback session ID and input it into your submission form

• If you're submitting a plugin or developer tool, also include installation instructions, supported platforms, and a way for judges to test your project without rebuilding it from scratch (such as a demo instance, sandbox, or test account)
