OpenAI Teams Up with Broadcom to Build Custom AI Chips
Partnership Overview
OpenAI disclosed a strategic alliance with Broadcom to design and manufacture custom AI accelerator chips intended for use in its data‑center infrastructure. The agreement positions Broadcom as the hardware partner that will enable OpenAI to produce "10 gigawatts of custom AI accelerators," a scale the company describes as comparable to the output of multiple large‑scale power plants.
Strategic Rationale
By developing its own chips, OpenAI seeks to reduce dependence on Nvidia, which currently dominates the AI‑accelerator market. The partnership also aims to embed insights gained from frontier model development directly into hardware, thereby unlocking new levels of capability and efficiency for OpenAI's suite of products.
Technical Ambitions
The custom chips are planned to be integrated into OpenAI's existing and future compute clusters, supporting a range of AI applications from conversational agents to advanced generative tools. The collaboration builds on earlier multi‑gigawatt agreements—six gigawatts with AMD and ten gigawatts with Nvidia—demonstrating OpenAI's broader strategy of diversifying its compute sources.
Timeline and Deployment
Broadcom is expected to begin rolling out rack‑level equipment in the second half of 2026. The full deployment of the agreed‑upon 10‑gigawatt capacity is projected to conclude by the end of 2029. OpenAI co‑founder and CEO Sam Altman highlighted the partnership as a "critical step in building the infrastructure needed to unlock AI’s potential and deliver real benefits for people and businesses."
Industry Context
The move aligns with a growing trend among major tech firms—such as Meta, Google, and Microsoft—to develop proprietary silicon solutions. This shift is driven by soaring AI demand, supply‑chain considerations, and the desire to attain greater control over performance characteristics. While custom chip projects have yet to pose a substantial threat to Nvidia's market dominance, they have opened substantial opportunities for alternative chipmakers like Broadcom.
