What Is OpenAI's Jalapeño AI Chip? A Simple Guide for Beginners
AI is not only about powerful models like ChatGPT. The hardware running those models also plays an important role. In June 2026, OpenAI introduced Jalapeño, its first custom AI inference chip, developed with Broadcom. On August 25, 2026, OpenAI shared its first measured performance results, showing that Jalapeño can deliver high AI performance while using power efficiently. So, what exactly is Jalapeño, why did OpenAI build its own chip, and does it mean OpenAI is trying to replace NVIDIA? Let's take a simple look. What Is OpenAI's Jalapeño AI Chip? Jalapeño is OpenAI's first custom AI chip designed specifically for AI inference . AI inference is the process of using a trained AI model to produce an answer or prediction from new input. For example, when you ask ChatGPT a question, the model processes your request and generates a response. The computing work involved in producing that response is called inference. A simple way to think about it is: Training = studying for a ...
