In the global race for AI dominance, most eyes are fixed on Silicon Valley, China, or Elon Musk’s latest ventures. But in a surprising twist, Denmark has entered the battlefield with Gefion—a national AI supercomputer that’s not just powerful, but sustainable, secure, and sovereign.
Named after the Norse goddess who turned barren land into fertile ground, Gefion is here to transform raw data into revolutionary breakthroughs.
What Is Gefion?
Gefion is Denmark’s most powerful AI supercomputer, housed in a state-of-the-art, 100% green-energy data center. It’s built on NVIDIA’s DGX SuperPOD architecture, featuring:
- 191 DGX H100 nodes
- A total of 1,528 NVIDIA H100 GPUs
- High-speed NVIDIA Quantum-2 networking
- Placement in the Top 25 global supercomputers (TOP500)
- Ranked in the Top 7 for I/O speed (IO500)
This positions Gefion as one of the fastest and most efficient AI systems in Europe.
Why Denmark Built It
While other countries rely heavily on foreign AI infrastructure and cloud providers, Denmark made a bold move: build AI at home.
Gefion is part of a larger vision to achieve “AI sovereignty”—the ability to develop advanced models using local languages, data, and ethics, free from outside influence.
Funded by:
- Novo Nordisk Foundation (yes, the same pharmaceutical giant behind Ozempic)
- EIFO (Export and Investment Fund of Denmark)
The supercomputer is managed by the Danish Centre for AI Innovation (DCAI), which is leading Denmark’s charge into AI, biotech, and quantum computing.
Real-World Use Cases
Gefion isn’t just sitting idle—it’s already working on groundbreaking projects across multiple fields:
Healthcare & Biotech
- Drug discovery using NVIDIA BioNeMo
- Genomic simulations for precision medicine
Climate & Energy
- AI-powered weather forecasting
- Carbon reduction modeling for greener cities
Language & Data
- Training AI in Danish and other regional languages
- Supporting privacy-first national data systems
Quantum Computing
- Simulations with NVIDIA CUDA-Q
- Development of quantum algorithms for future tech
Why Gefion Matters Globally
In a world dominated by U.S. and Chinese AI giants, Gefion represents something radical:
A European nation taking control of its own AI destiny.
This means:
- Data stays local (especially important in healthcare)
- Ethical standards remain high
- National security and innovation are protected
As AI systems become as critical as electricity or water, countries like Denmark are proving that you don’t need scale to make an impact—you need vision.
What’s in a Name?
The name “Gefion” is more than poetic. In Norse mythology, Gefion transformed barren land into thriving farmland. That metaphor carries weight here: Denmark is transforming its digital landscape using raw data and AI compute power.
The Future of Gefion
As of 2025, Gefion is already contributing to scientific research, healthcare, education, and even public services. It is also paving the way for other European countries to rethink how they handle their AI infrastructure.
The question now is: Will the world follow Denmark’s lead?
Gefion isn’t just a technological achievement—it’s a strategic milestone in the evolution of responsible AI. In an age of global cloud giants and black-box models, Denmark’s national supercomputer stands for something bigger:
Sovereignty. Transparency. Sustainability.
And that might just be what the world needs next.
