OpenAI unveils Jalapeño, its first custom AI chip — built with Broadcom for LLM inference, deploying by end of 2026

OpenAI and Broadcom announced Jalapeño on June 24, 2026 — OpenAI's first custom 'Intelligence Processor,' an accelerator designed from the ground up for LLM inference. Co-developed with Broadcom and Celestica, it went from design to tape-out in nine months (reportedly the fastest ASIC cycle ever), with OpenAI's own models used to speed development. OpenAI claims performance-per-watt 'substantially better' than current state of the art. Initial deployment is end of 2026 at gigawatt scale with Microsoft and other partners. OpenAI joins Google, Amazon, Microsoft, and Anthropic in building its own silicon — here's what it means for the AI tools you use.
