OpenAI just showed off Jalapeño, its first home-grown AI chip, built with Broadcom. It is designed for inference, not training. And it is the clearest sign yet that the company most dependent on Nvidia wants a way out.
OpenAI has a chip now. On Wednesday it unveiled Jalapeño, the first piece of silicon it has designed itself. It is a pointed answer to a question that has hung over the company for years. What happens when the world’s biggest buyer of AI compute decides it no longer wants to rent all of it from Nvidia?
The chip was built with Broadcom, Axios first reported. OpenAI did the core design. Broadcom brought the connectivity and networking know-how, plus its Tomahawk switching silicon. A third partner, Celestica, handled the boards and racks.
OpenAI is already running the first samples in its labs. There they answer Codex queries and run workloads for a model it calls GPT-5.3-Codex-Spark.
OpenAI is not trying to replace Nvidia overnight. It is trying to stop being a captive customer. That is the real story here.
