OpenAI and Broadcom unveil LLM-optimized inference chip

OpenAI and Broadcom have unveiled Jalapeño, a specialized AI accelerator chip (a processor designed to speed up artificial intelligence computations) built specifically for LLM inference (the process of running trained AI models to generate outputs). Early testing shows the chip delivers significantly better performance per watt (computational power relative to energy use) than current alternatives, and it will be deployed in data centers starting in 2026.
