OpenAI's First Custom AI Chip 'Jalapeño' Built with Broadcom

June 24, 2026

OpenAI has taped out its first custom silicon, Jalapeño, co-developed with Broadcom and purpose-built for LLM inference workloads across ChatGPT, Codex, and the API. The chip signals OpenAI's move toward vertical integration of compute, reducing dependence on Nvidia. No specs, die size, or performance numbers have been disclosed.

HOW THIS AFFECTS YOU

●

builderOpenAI's own silicon could eventually shift API pricing and latency characteristics as inference costs change with proprietary hardware.

●

founderWorth watching because custom silicon gives OpenAI structural cost advantages over API-dependent competitors and signals long-term infrastructure independence.

●

investorThis changes the competitive moat calculus for OpenAI — vertical integration from model to chip reduces Nvidia dependency and improves margin potential ahead of IPO.
