Jalapeño: OpenAI’s First Chip Could Change the AI Race

OpenAI has just unveiled Jalapeño, its first in-house artificial intelligence chip, designed in just 9 months with help from GPT-5.5. Built with Broadcom and TSMC, this inference ASIC could dramatically reduce ChatGPT’s costs and mark the beginning of a new era for the company.

We explain how the chip manufacturing chain works (OpenAI, Broadcom, TSMC), why OpenAI needs to become independent of Nvidia, the difference between training and inference, and how Jalapeño compares with chips from Google, Amazon, Microsoft, and Meta. This is not just about technology: it is an infrastructure, control, and computing-power race that will redefine AI by 2027–2028.
