OpenAI is reportedly launching its first AI chip, Titan, by the end of 2026, co-developed with Broadcom and manufactured on TSMC's 3nm process. The successor, Titan II, is rumored to use TSMC's A16 process. Additionally, OpenAI has supposedly chosen Samsung's 2nm Exynos chip for its 'Sweetpea' AI earbuds.
