OpenAI unveils its first custom chip, Jalapeño, made with Broadcom to reduce reliance on Nvidia and handle surging demand for AI inference.

Key takeaway

OpenAI and Broadcom unveiled Jalapeño, OpenAI's first custom AI chip, designed to serve the company's inference workloads more efficiently and at lower cost than existing alternatives. Announced on Wednesday, the chip is planned for initial deployment by end of 2026, with significant scaling through 2027 and into early 2028. This move reflects OpenAI's strategy to build its own computing stack and address an acute shortage of AI processing capacity as demand from its customers grows beyond what existing suppliers can provide.

3 Key Points

  • What happened

    OpenAI and Broadcom on Wednesday announced Jalapeño, OpenAI's debut custom silicon chip designed to run AI models in production. The companies designed the chip in nine months and plan initial deployment by the end of 2026, with scaling through 2027 and into the first half of 2028.

  • Why it matters

    OpenAI says it 'cannot get compute fast enough' and Broadcom's CEO confirmed that demand from his six largest customers is 'simply insatiable.' By designing its own chips alongside the broader computing stack, OpenAI aims to serve more AI capability with greater efficiency, reducing its dependence on Nvidia's expensive GPUs and addressing a critical supply constraint.

  • What to watch

    Jalapeño is an ASIC (application-specific integrated circuit), which industry experts say is less flexible than Nvidia's GPU but also less expensive and customizable for specific AI tasks. The companies ultimately aim to build enough capacity to require 10 gigawatts of power, signaling massive infrastructure growth over the coming years.

FAQ

When will the Jalapeño chip be available to use?
The companies are aiming for initial deployment of the Jalapeño chips by the end of 2026, expanding in the years ahead. There will be small prototype development in late 2026, then scaling in 2027 and ramping up fully in the first half of 2028.
How is Jalapeño different from the Nvidia GPUs OpenAI has been using?
Jalapeño is an ASIC (application-specific integrated circuit), which industry experts say is less flexible than Nvidia's GPU but also less expensive and can be designed for specific AI tasks. OpenAI designed the chip and large parts of the computer system where it will be used.
Why is OpenAI building its own chip instead of buying more from Nvidia?
OpenAI President Greg Brockman told CNBC that the company 'cannot get compute fast enough,' and Broadcom CEO Hock Tan confirmed that compute demand is 'simply insatiable' and 'much more than we can address.' By designing its own chip, OpenAI can serve more intelligence with greater efficiency and keep pushing advanced AI toward broader access.
