How Codex ran OpenAI DevDay 2025
Blog post from OpenAI
OpenAI's third and largest DevDay in San Francisco heavily relied on Codex, marking its debut at the event to assist in various aspects, from stage demos to arcade machines, and app development. Codex played a crucial role in efficiently solving complex tasks, such as controlling cameras and lights using outdated protocols, building apps with engaging interfaces, and developing video games for arcade cabinets by supporting simultaneous development processes. Developers utilized Codex to streamline workflows, create intuitive UIs, evaluate architectural decisions, and manage extensive documentation efforts. The tool's versatility allowed teams to multitask effectively, manage last-minute updates, and enhance project outcomes, significantly reducing the time and effort required for tasks that would have otherwise been cumbersome and prolonged.
