Broadcom to help OpenAI make AI chip to take on Nvidia

Chip giant is among the chip designers benefiting from a boom in AI development

SEATTLE - Chip giant Broadcom is helping ChatGPT maker OpenAI design and produce an artificial intelligence (AI) accelerator from 2026, getting into a lucrative sphere dominated by Nvidia.

The two firms plan to ship the first chips in that line-up starting in 2026, a person familiar with the matter said. OpenAI will initially use the chip for its own purposes, the Financial Times reported.

Broadcom chief executive officer Tan Hock Eng made veiled references to that partnership on Sept 4 when he said it had secured more than US$10 billion (S$12.9 billion) in orders from a new customer which the person identified as OpenAI for its custom accelerator business.

Accelerators are essential to the development of AI at big tech firms. Bloomberg News previously reported that OpenAI and Broadcom were working on an inference chip design, intended to run or operate AI services after they had been trained.
