Artificial Intelligence Helped OpenAI Prototype Gadget in Less Than a Week Two OpenAI employees used GPT-6 and Astra models to design a prototype in less than a week, and about a month later a contract manufacturer produced a trial batch. The gadget allows you to interact with the codex programming AI assistant through a physical interface. With this experiment, OpenAI wanted to test how well modeling can take hardware development from the initial idea to a working prototype.
