Oracle has launched the Oracle Cloud Infrastructure (OCI) Zettascale10. It’s the biggest AI supercomputer in the cloud. This system is built to meet the rising needs of advanced AI workloads. This next-gen system links hundreds of thousands of NVIDIA GPUs in several data centers. It creates powerful multi-gigawatt clusters that achieve up to 16 zettaFLOPS of peak performance. OCI Zettascale10 is based on Oracle’s Acceleron RoCE networking. It provides low GPU-to-GPU latency and high reliability. Its price-performance is industry-leading. This makes it great for large-scale AI training and inference tasks.The system is deployed at the Stargate supercluster site in Abilene, Texas, in collaboration with OpenAI, and is expected to be available to customers in the second half of 2026.

“With OCI Zettascale10, we’re fusing OCI’s groundbreaking Oracle Acceleron RoCE network architecture with next-generation NVIDIA AI infrastructure to deliver multi gigawatt AI capacity at unmatched scale,” said Mahesh Thiagarajan, executive vice president, Oracle Cloud Infrastructure. “Customers can build, train, and deploy their largest AI models into production using less power per unit of performance and achieving high reliability.” Peter Hoeschele, vice president, Infrastructure and Industrial Compute at OpenAI, added, “The highly scalable custom RoCE design maximizes fabric-wide performance at gigawatt scale while keeping most of the power focused on compute. We’re excited to keep scaling Abilene and the broader Stargate program together.” Ian Buck, vice president of Hyperscale at NVIDIA, remarked, “OCI Zettascale10 provides the compute fabric needed to advance state of the art AI research and help organizations everywhere move from experimentation to industrialized AI.”
In addition to the Zettascale10, Oracle and AMD have expanded their partnership to offer cloud services powered by AMD’s upcoming MI450 artificial intelligence chips. Starting in Q3 2026, Oracle plans to deploy 50,000 MI450 processors as part of a new AI supercluster, with further expansion in 2027 and beyond. This collaboration aims to meet the growing demand for AI infrastructure supporting tools like ChatGPT, enhancing Oracle’s AI capabilities and strengthening AMD’s position in the AI chip market.
