Spend an afternoon with Codex! Join us for OpenAI Build Week through a Saturday afternoon of building with Codex and the latest OpenAI models. This event is for passionate builders, technical creators, and dreamers. Enjoy a high-signal environment of fellow Codex enthusiasts to make exciting new projects, prototypes, and solutions that weren't previously possible. Bounce ideas off others, learn from each other, collaborate and ideate to build a product, MVP, or prototype that you're truly proud of. Hack Day is the Sol to Demo Day's Luna: those who build something persuasive this afternoon get the chance to showcase their work during Demo Day on Sunday!
