Unveiling OCI Zettascale10: The Future of AI Cloud Computing

On October 14, 2025, during the highly anticipated Oracle AI World event, Oracle introduced its latest advancement—Oracle Cloud Infrastructure (OCI) Zettascale10, touted as the largest AI supercomputer available in the cloud. This groundbreaking system not only showcases Oracle’s commitment to innovation but also redefines what is possible in artificial intelligence operations.

A Revolution in Performance

The OCI Zettascale10 supercomputer is built to deliver a staggering 16 zettaFLOPS of peak performance. By linking hundreds of thousands of NVIDIA GPUs across multiple data centers, it creates an extensive and powerful multi-gigawatt cluster that is optimized for massive AI workloads. This infrastructure underpins collaborative projects such as the Stargate supercluster—developed in partnership with OpenAI in Abilene, Texas.

Mahesh Thiagarajan, Oracle's Executive Vice President for Cloud Infrastructure, emphasized that this new cluster merges cutting-edge technology with immense power capacity. "Our technology allows clients to build, train, and deploy their largest AI models efficiently while significantly minimizing power use per performance unit,” he remarked.

Optimized Architecture

The Zettascale10 utilizes Oracle Acceleron RoCE networking architecture alongside NVIDIA's state-of-the-art AI infrastructure. This networking design effectively reduces latency within the GPU clusters, providing unparalleled performance for customers engaged in extensive AI training workloads. Notably, these clusters are located in large data center campuses that are strategically designed for maximum efficiency, ensuring high performance within a compact radius of operations.

The architecture also prioritizes speed and reliability, allowing for better utilization and robustness, qualities essential for today's demanding AI applications. Peter Hoeschele from OpenAI noted, "Our collaborative efforts have focused on maximizing performance while maintaining a stable power-to-compute ratio for extensive AI solutions."

Key Features and Innovations

Oracle Acceleron RoCE networking embodies several pivotal benefits:
1. Scalability: By using modern GPU Network Interface Cards (NICs) for connectivity, the network architecture supports a wider and more versatile deployment of AI clusters.
2. High Reliability: This design minimizes the risk of disruptions by managing traffic across isolated network planes effectively.
3. Consistent Performance: The integration of a simplified network facilitates more predictable GPU-to-GPU communication, vital for large-scale AI training sessions.
4. Power Efficiency: Utilizing advanced optical technologies helps reduce the cooling and energy requirements without compromising on throughput capabilities.
5. Operational Flexibility: Enhanced maintenance and independent updates enable quicker deployments and feature enhancements, reducing potential system downtime.

Market Potential and Future Prospects

OCI Zettascale10 is poised to reshape the dynamics of cloud-based AI services. Oracle plans to make this system available for deployment to customers in multi-gigawatt configurations, initially targeting the activation of up to 800,000 NVIDIA GPUs. With a focus on performance predictability and cost efficiency, Oracle promotes this cutting-edge solution as an ideal choice for companies striving to transition from AI experimentation to industrial-grade applications.

Ian Buck, Vice President of Hyperscale at NVIDIA affirmed the partnership's commitment, stating, "By leveraging OCI's distributed cloud synergy with our advanced AI infrastructure, we are well-positioned to facilitate AI at unprecedented scales, empowering organizations globally."

Conclusion

As Oracle opens the doors for orders of the OCI Zettascale10 set for release in the latter half of the next calendar year, it's clear that this innovation in AI cloud computing represents a substantial leap forward in potential for enterprises. The synergy between Oracle and NVIDIA, alongside the deployment in collaboration with OpenAI, signifies a monumental shift in how organizations can harness the power of AI for their operational needs. With its remarkable features and capabilities, OCI Zettascale10 stands ready to set a new standard in the cloud computing landscape.
