June 24, 2026 Company OpenAI and Broadcom unveil LLM-optimized inference chip Loading… Share Designed to be the best inference platform for LLMs Designed to be the best inference platform for LLMs Nine-month tape-out, accelerated by OpenAI models Building a multi-generation platform with partners Making advanced AI more broadly available Table of contents Designed to be the best inference platform for LLMs Nine-month tape-out, accelerated by OpenAI models Building a multi-generation platform with partners Making advanced AI more broadly available Early testing shows that the first-generation accelerator will deliver performance per watt substantially better than current state-of-the-art Built from the ground up for current and future LLMs across the industry Developed from design to production in nine months, accelerated by OpenAI’s models Expands OpenAI’s full-stack platform, from products to models and now to chips To be deployed at gigawatt scale with data center partners, over multiple generations OpenAI and Broadcom (NASDAQ: AVGO) today unveiled Jalapeño, OpenAI’s first Intelligence Processor: an accelerator architected around OpenAI’s vision for the future of LLM inference, and the first AI accelerator in a multi-generation compute platform the companies are building together to make advanced AI faster, more reliable, and more accessible to more people. Jalapeño was delivered to OpenAI CEO Sam Altman and President Greg Brockman by Broadcom President and CEO Hock Tan and President Charlie Kawwas, marking an important step in OpenAI’s strategy to build the full stack behind its models and products. OpenAI designed the chip from scratch around its deep understanding of LLM fundamentals, informed by its roadmap of models, kernels, serving systems, and product needs, with partners Broadcom and Celestica, helping industrialize the platform through chip implementation, board, rack system integration, high-performance networking, and scalable production systems. Jalapeño is designed with flexibility to work with all LLMs guided by OpenAI’s insights into the inference needs of current and future AI models across the industry. Engineering samples of the Jalapeño chip are running ML workloads in the lab at production target frequency and power, including GPT‑5.3‑Codex‑Spark. While OpenAI is still measuring final performance, early testing shows that Jalapeño will deliver performance per watt substantially better than current state-of-the-art. A detailed technical report on performance will be presented in the coming months. The architecture reduces data movement and balances compute, memory, and networking resources to achieve realized utilization much closer to theoretical peak performance. Broadcom’s silicon implementation and networking technologies, including Tomahawk networking silicon, help bring the platform to large-scale production. “The world is moving to a compute-powered economy,” said Greg Brockman, President and Co-Founder of OpenAI. “Jalapeño is part of our long-term full-stack infrastructure strategy to make compute more abundant, resulting in AI which is faster, more reliable, more affordable for people and businesses, and can be used to solve more important problems. By designing more of the stack ourselves, we can serve more intelligence with greater efficiency and keep pushing advanced AI toward broader access.” “Jalapeño was designed from the ground up for LLM inference using detailed insights from our close collaboration with OpenAI researchers,” said Richard Ho, who leads OpenAI’s hardware program. “We optimized the architecture around the kernels, memory movement, networking, and serving patterns that matter most for frontier AI models. Based on early testing, Jalapeño will efficiently execute our most important workloads close to the hardware’s theoretical limits.” “Our collaboration with OpenAI represents a fundamental commitment to scaling the physical infrastructure required for the next decade of AI,” s
