Gefion: Inside the AI Supercomputer Reshaping Denmark’s Future
Denmark is now home to one of the world's most powerful AI supercomputers, Gefion. Find out how this technological powerhouse is unlocking new frontiers in science and industry.
Introduction: In the global race for AI supremacy, a small nation is making a giant leap. Denmark recently unveiled “Gefion,” a national AI supercomputer poised to transform its industries, from healthcare to sustainable energy.
As the demand for computational power to train and run artificial intelligence models skyrockets, countries are investing in supercomputers that can handle such intense workloads. Gefion represents Denmark’s strategic move to become an AI-driven innovation hub.
This article takes you inside Gefion: what it is, who built it, and how it’s already reshaping Denmark’s future.
What is Gefion and Why is it so Powerful? Gefion is Denmark’s national AI supercomputer designed to provide massive computational power to researchers, scientists, and companies working on AI and data-intensive problems.
At its core:
Gefion is built on the NVIDIA DGX SuperPOD architecture, a scalable platform used by some of the most powerful AI systems in the world.
It includes 1,528 NVIDIA H100 Tensor Core GPUs, highly specialized processors optimized for AI workloads like training large language models.
The system uses NVIDIA Quantum-2 InfiniBand networking, allowing lightning-fast communication between GPUs to keep up with the demands of complex computations.
Think of Gefion as thousands of AI-optimized processors working together like a giant, ultra-fast brain.
Who is Behind Gefion? A Public-Private Partnership Gefion is the result of a strategic collaboration:
Danish Centre for AI Innovation (DCAI) operates and owns the system.
Novo Nordisk Foundation provided major funding, signaling biotech industry commitment.
Export and Investment Fund of Denmark (EIFO) supported the initiative with public investment.
NVIDIA supplied the critical hardware and software expertise.
Eviden constructed and integrated the system.
This unique public-private model empowers Denmark to maintain “sovereign AI” capabilities — controlling its own AI infrastructure without dependence on foreign cloud platforms.
Real-World Impact: What Will Gefion Do? Gefion’s power isn’t theoretical. It’s already driving innovation in key sectors:
Drug Discovery: Novo Nordisk is using Gefion to accelerate drug development, analyzing massive datasets and simulating molecular interactions faster than ever.
Climate Solutions: Scientists are employing Gefion for climate modeling and optimizing renewable energy systems, supporting Denmark’s green transition.
Academic Research: Universities and research institutions are using Gefion for projects in quantum computing, genomics, and advanced physics.
Economic Development: Danish startups and tech companies now have access to infrastructure that rivals the world’s best, fostering competitive innovation.
A Milestone in National AI Strategy Gefion was launched in October 2024 in a ceremony attended by King Frederik X and NVIDIA CEO Jensen Huang, underlining its significance to the nation.
With its powerful specs and strategic deployment, Gefion is now ranked among the top AI supercomputers globally, putting Denmark firmly on the map as a leader in responsible and sovereign AI.
Final Thoughts: Setting a New Standard Gefion is not just a machine—it’s a national asset. It exemplifies how public-private partnerships can drive cutting-edge innovation and enable smaller nations to punch above their weight in the global tech arena.
As countries worldwide consider their AI strategies, Denmark has set a compelling example with Gefion.
The future of AI isn’t limited to Silicon Valley—it’s being written in Copenhagen too.
