OpenAI is deepening its collaboration with Samsung Electronics on next-generation chips and AI accelerators, moving beyond its existing TSMC relationship. Harrison Kim revealed joint research and production efforts at a Seoul press conference, while Samsung emerges as one of the largest global ChatGPT enterprise deployments with 28-fold user growth in South Korea.

OpenAI Samsung Partnership Targets Next-Generation Chips

OpenAI is expanding its semiconductor supply chain by partnering with Samsung Electronics on next-generation chips, marking a strategic shift beyond its current reliance on TSMC. Harrison Kim, General Manager of OpenAI Korea, announced at a Seoul press conference that joint research and production on AI accelerators represents one of the most significant areas of progress between the two companies

Double-Sourcing Strategy Addresses Massive Volume Requirements

The OpenAI Samsung partnership signals the ChatGPT maker's intention to implement a double-sourcing with TSMC strategy, similar to Tesla's approach with its AI5 processors. As a fabless chip designer, OpenAI faces intense competition for leading-edge capacity from AMD, Nvidia, and other hyperscalers developing custom AI chips

2

. OpenAI's existing agreement with Broadcom to procure 10GW of custom AI accelerators underscores the massive scale of its chip requirements

1

. Data center accelerators demand vastly more silicon per unit compared to automotive or robotics applications, and if OpenAI needs gigawatts of large leading-edge processors with multiple dies, wafer requirements could exceed TSMC's available capacity

High-Bandwidth Memory and Advanced Packaging Considerations

The semiconductor supply chain collaboration likely extends beyond logic chips to address critical high-bandwidth memory (HBM) needs. Samsung Electronics, alongside SK Hynix and Micron, represents one of only three manufacturers capable of producing HBM in volume

2

. OpenAI's Jalapeño chip uses HBM4 technology, suggesting its successor will likely adopt the faster HBM4E standard

2

. Securing adequate HBM supply requires early partnerships, particularly as next-generation chips may leverage custom base dies to move memory controllers or logic from compute silicon to the HBM stack itself

. Samsung and SK Hynix signed letters of intent last year to supply memory chips for OpenAI's Stargate data center project

Samsung Foundry Emerges as Viable Alternative

Samsung's 2 nm process technology and advanced packaging capabilities position the foundry as a credible alternative to TSMC for AI infrastructure development. While Samsung previously faced yield challenges with its 3 nm process, recent proof points from companies like Rebellions, Tenstorrent, and Groq demonstrate the foundry's ability to produce sophisticated AI accelerators

2

. Rebellions' Rebel100 accelerator particularly validates Samsung's capabilities, utilizing multi-die architecture and HBM3E—both requiring advanced packaging techniques

. The strategic partnership between Samsung Electronics and Broadcom, valued at over $200 billion through 2030, further facilitates OpenAI's ability to produce accelerators at both Samsung and TSMC foundries
