OpenAI and Broadcom Unveil Jalapeño, a Breakthrough AI Chip

In a significant move, OpenAI and Broadcom have announced the design of their first jointly-developed chip, Jalapeño. This custom AI accelerator is the result of a collaboration that began in October 2025, with the goal of creating a processor tailored to OpenAI's large language models. According to OpenAI, Jalapeño boasts impressive performance per watt, outpacing current state-of-the-art chip technology. While final performance testing is still underway, the company promises a more detailed technical report in the coming months. The initial deployment of Jalapeño is slated for late 2026, with the chip set to be used in data centers. This marks a major milestone for OpenAI, as it enters the chip production market and gains greater control over the components that power its ChatGPT models. By developing its own chips, OpenAI aims to increase efficiency and expand the accessibility of its tools. Notably, Jalapeño was co-developed in just nine months, a feat made possible by the close collaboration between OpenAI's engineering teams and Broadcom's silicon expertise. This partnership is poised to yield a multi-generation compute platform, designed to make advanced AI faster, more reliable, and more accessible to a broader audience.
