OpenAI has unveiled its first custom AI chip, developed in partnership with Broadcom, which may potentially challenge Nvidia's position in the market. The new chip, called Jalapeño, is an AI inference chip that was reportedly developed with the help of OpenAI's own models. The move suggests that OpenAI is seeking alternatives to Nvidia, possibly due to dissatisfaction with some of their chips, although the exact implications for Nvidia's market share are unclear.
