NVIDIA and Oracle announced plans to build the Department of Energy's largest AI supercomputer in its history, in an effort to revolutionize scientific discovery.

One of the AI supercomputers being developed as part of this plan is Solstice, which will be equipped with 100,000 NVIDIA Blackwell GPUs and will support the DOE's mission of 'developing AI capabilities to advance American technological leadership in national security, science, and energy.'

The other AI supercomputer, 'Equinox,' will be equipped with 10,000 NVIDIA Blackwell GPUs and is scheduled to be available in the first half of 2026. The two systems will be interconnected via the NVIDIA network and will deliver a combined AI performance of 2,200 EFLOPS .

Solstice and Equinox will be deployed at Argonne National Laboratory , a DOE national laboratory. Scientists and researchers can develop and train new frontier models for open science and AI inference models using NVIDIA Megatron-Core , an open-source library for training AI models, and extend it with NVIDIA TensorRT, an ecosystem of tools for deep learning inference. These models will serve as the foundation for agent-based AI workflows for scientific discovery.

Solstice and Equinox will support research collaboration between NVIDIA, DOE, and Argonne National Laboratory to help develop scientists. NVIDIA claimed this will increase R&D productivity and accelerate publicly funded discoveries over the next decade. Solstice will build on the DOE's new public-private partnership model, which includes industry investments and use cases. This reflects the Trump Administration's commitment to ensuring American leadership in AI and science.

'AI is the most powerful technology of our time and science at its greatest frontier,' said Jensen Huang, CEO of NVIDIA. 'Together with Oracle, we are building the largest supercomputer in DOE history. This supercomputer will power American discovery and give researchers access to cutting-edge AI infrastructure to drive advancements in a wide range of fields, from medical research to materials science.'

'Winning the AI race requires new and creative partnerships that bring together the brightest minds and industries in American technology and science,' said DOE Secretary of State Chris Wright. 'The two systems at Argonne National Laboratory and the collaboration between DOE, NVIDIA, and Oracle represent a new, common-sense approach to computing partnerships. These systems will power scientific and technological innovation. Thanks to President Trump, we can bring new computing power online faster than ever before and transform our shared innovation into national power.'

'Equinox and Solstice are designed to accelerate a wide range of scientific AI workflows, and we are working with Oracle and NVIDIA to help thousands of researchers effectively leverage these systems' groundbreaking capabilities,' said Paul K. Kearns, director of Argonne National Laboratory. 'The systems will seamlessly connect with DOE's cutting-edge experimental facilities, including the Advanced Synchrotron Radiation System (APS), enabling scientists to address some of America's most pressing challenges through scientific discovery.'

'Oracle is proud to partner with the DOE to deliver sovereign-level, high-performance AI capabilities,' said Oracle CEO Clay McGuire. 'Our collaboration at Argonne National Laboratory, leveraging the power of Oracle Cloud Infrastructure (OCI), will provide a critical resource to address America's most complex challenges and accelerate the next wave of scientific breakthroughs.'
