Danish universities launch sovereign AI platform for research and innovation: UCloud AI

UCloud AI brings advanced language models, national supercomputing power and secure digital infrastructure together in one platform. Developed as a public service rather than a commercial AI product, the new platform aims to make artificial intelligence more accessible to researchers across Denmark.

Odense/Aarhus/Aalborg, 14 September 2026.

Artificial intelligence is creating new opportunities across research, industry, and the public sector. Making use of the technology often requires access to powerful computing resources, specialist expertise and solutions that can handle data securely. With the launch of UCloud AI, the Danish universities are bringing these capabilities together in a new sovereign AI platform.

Developed by the University of Southern Denmark, UCloud AI is integrated into the national research platform UCloud and runs on the AI supercomputer BITTEN located in Sønderborg. It provides access to advanced language models through a familiar digital workspace, allowing users to work with AI alongside their existing data, storage, and applications. The service builds on the existing collaboration between SDU, Aarhus University and Aalborg University in the DeiC Interactive HPC consortium.

The platform is designed to support a wide range of users and purposes. At launch, researchers and students at Denmark’s eight universities can access the service through their existing university login, and in a little while also companies and organizations, or people who simply need a secure and accessible way to use the technology, will also be able to gain access to the service.

“Our ambition is to make advanced AI available to everyone who can benefit from it, not only to those who have the technical expertise or resources to build their own infrastructure. With UCloud AI, we are bringing powerful models, computing resources and a secure digital environment together in one place. It is a public service built on Danish infrastructure, where users can work with AI without giving up control of their data or intellectual property, at a significantly lower cost than other providers. We believe this can open up entirely new possibilities for research, innovation and the wider society”, Says Claudio Pica, Professor and Director of the SDU eScience Center at the University of Southern Denmark.

SDU will also collaborate with the Danish Centre for AI Innovation (DCAI), which owns and operates Gefion, Denmark’s national AI supercomputer. Researchers whose projects need to scale or have specialized computing requirements will be able to also access Gefion through UCloud AI. This collaboration points toward a future in which several supercomputing infrastructures could be accessed through a single platform, giving researchers greater flexibility and creating new opportunities for ambitious research and innovation.

Public, sovereign AI infrastructure built for sensitive work

UCloud AI is open source and operates within UCloud’s existing security framework and data processing agreements. AI processing takes place in Denmark, supporting sensitive research and organizational work while reducing dependence on external commercial providers. The platform combines AI models, data, storage, and HPC resources in one environment, with both a chat interface and an OpenAI-compatible API for developing more advanced applications.

“AI is a strategic priority across all Danish universities, and if we want to remain at the forefront of research and innovation, we also need the sovereign infrastructure to support that ambition. UCloud AI gives researchers access to advanced AI while keeping control of data and critical infrastructure in Denmark. This strengthens our ability to develop knowledge and technology on our own terms and, ultimately, to create value for society as a whole,” says Jens Ringsmose, Rector of the University of Southern Denmark and Chair of Universities Denmark.

“Secure and accessible AI infrastructure is becoming increasingly important for Danish research. From Aalborg University’s perspective, UCloud AI is an interesting addition to the national research infrastructure and a good example of how existing collaboration can give researchers access to new capabilities,” says Thomas Bak, Dean of the Technical Faculty of IT and Design at Aalborg University.

UCloud users are ready for the new platform

At Aarhus University, researchers have already used UCloud to investigate how language models respond to more than 3,000 dilemmas from the radio programme Sara & Monopolet, examining how closely their advice resembles that of the human panel. Another example is Lex.llm, a collaboration with Lex.dk exploring how generative AI can be combined with quality-assured Danish knowledge. UCloud AI will make it easier for projects such as these to access models and develop applications without establishing their own model infrastructure.

The platform will also provide an important link to Danish Foundation Models (DFM), a national research initiative developing open Danish language models. By making models developed through DFM available directly in UCloud AI, the same infrastructure can support the entire journey from developing and testing new AI models to making them accessible for research and new applications.

“Fluent Danish is only part of what we need from a language model. We also need to understand how it handles Danish knowledge, social norms and cultural context. Model development and practical application need to inform each other: we need access to competitive open models that we can evaluate and integrate into applications, while experience from those applications helps us identify where the models need to improve. UCloud AI provides an important connection between these activities, allowing us to study AI systematically and build with it, while reducing dependence on commercial API providers and giving us greater control over the models we use,” says Kristoffer Nielbo, Professor and Head of the Center for Humanities Computing at Aarhus University and Research Lead for Danish Foundation Models.

Research Supercomputing UCloud Use case

Danish language model project enters a new phase with stronger national computing power

How do we ensure that the artificial intelligence of the future understands the Danish language, Danish institutions, and Danish society – while handling data within frameworks that we control ourselves?

This question lies at the heart of the research project Danish Foundation Models (DFM), where the University of Southern Denmark, Aarhus University, the University of Copenhagen, and the Alexandra Institute are collaborating to develop open Danish language models. The project has been underway for some time, and researchers have already released the first models, established benchmarks, and initiated collaborations with external partners. Now, the project is entering its next phase.

With access to the new national AI supercomputing facility BITTEN, inaugurated in Sønderborg in May, and accessible through the research platform UCloud, the pace of development can increase significantly.

Culture, norms, and societal understanding are lost

Within just a few years, language models have become a strategic technology. They are already used for text generation, search, decision support, automation, and analysis. However, the most widespread models have been developed by global companies and trained primarily on English and other major languages.

This creates limitations when such models are expected to operate within a Danish context.

“If you look closely at the details, many international models are actually poor at Danish. The way they formulate themselves often resembles English translated into Danish. That is not how we speak or write,” says Professor Peter Schneider-Kamp from the University of Southern Denmark, who leads DFM on behalf of SDU.

The challenge extends beyond language. It also concerns culture, social norms, and an understanding of society.
DFM has, among other things, developed Danish benchmarks that test models on knowledge of Danish culture. Here, even the largest international models often perform poorly.

“They lack an understanding of how Denmark works – our literature, our public institutions, our healthcare system, and our cultural points of reference,” Schneider-Kamp explains.

Denmark cannot remain on the sidelines

The development of AI is moving so rapidly that access to domestic expertise and infrastructure is becoming increasingly important. According to Schneider-Kamp, it is risky to assume that other countries will continue to provide the services and models that Europe needs indefinitely.

“We cannot simply rely on American or Chinese companies to provide the right solutions for us forever. We need to take part in the development ourselves,” he says.

This is not about replicating Silicon Valley at the same scale, but about being able to develop solutions tailored to Danish needs – and doing so on a transparent and responsible foundation.

“We want models where we know what they have been trained on, that comply with GDPR and the AI Act, and that understand the Danish language, Danish culture, and Danish norms,” he says.

UCloud is the backbone

Behind the project lies a less visible, but crucial part of the story: research infrastructure.

DFM is developed to a large extent using UCloud, the national platform for interactive high-performance computing developed by SDU eScience Center together with partners. It provides researchers with access to storage capacity, GPUs, software, and collaboration tools in one integrated environment.

For Peter Schneider-Kamp, UCloud is absolutely central.

“UCloud is our secure environment where we develop models, train models, store data, and evaluate them. It is absolutely central to everything we do,” he says.

The security perspective is essential. When researchers work with large amounts of data – and in some projects also sensitive data – it is critical that the data can be handled within a controlled environment.

“If we receive new datasets from, for example, libraries, media organisations, or other sources, we can store them securely, work directly on them, and maintain control over the data,” he says.

The alternative is often more complex and fragmented solutions where data has to be moved between systems and countries.

New national supercomputer BITTEN

On 5 May 2026, a new national supercomputer was inaugurated in Sønderborg: BITTEN. The facility was established by the University of Southern Denmark in collaboration with Danfoss and Hewlett Packard Enterprise (HPE) and forms part of the Danish research infrastructure for artificial intelligence, advanced computing, and data-intensive research.

The supercomputer is made available through UCloud, allowing researchers and students at universities across Denmark to access it through their existing systems and workflows.

The collaboration combines SDU’s experience in research infrastructure, Danfoss’ expertise in energy-efficient cooling and heating solutions, and HPE’s knowledge of supercomputing and data centre technology.

The facility has also been designed with a strong focus on energy-efficient operation and the reuse of excess heat.

Lack of computing capacity slows down research

For AI research, access to computing power is not a luxury – it is a prerequisite.

Previously, the DFM group regularly experienced bottlenecks when training models.

“Sometimes we have had to wait two, three, four, or even five days to get access to a GPU. Meanwhile, PhD students and postdoctoral researchers are sitting ready with ideas and code but are held back by a lack of resources,” says Peter Schneider-Kamp.

This is precisely where the new capacity can make a difference.

More computing power means faster experiments, larger models, more iterations, and a shorter path from idea to result.

“We hope it will allow us to turn ideas into research results and concrete use cases much faster. We are incredibly excited to gain access to the many additional GPUs,” he says.

More than technology

DFM is therefore about more than software and hardware. The project illustrates how research, digital sovereignty, data security, and innovation are closely connected.

If Denmark wants to use AI in healthcare, the public sector, education, and industry, it requires solutions that can be understood, adapted, and trusted.

With UCloud as its operational backbone and the new national supercomputing capacity of BITTEN, Danish Foundation Models now stands at a point where the work can move from a promising development phase to broader implementation.

The question is no longer only whether Denmark can develop its own language models.

The question is whether we can afford not to.

Interactive HPC Research UCloud Use case

DeiC Interactive HPC Crucial for Danish AI Language Models

By Jasper Riis-Hansen and Line Ejby Sørensen, Center for Humanities Computing (CHC), Aarhus University

DeiC Interactive HPC – UCloud plays a central role in the Danish Foundation Models (DFM) project, which forms part of the Danish government’s strategic initiative for artificial intelligence.

Danish Foundation Models (DFM) is supported by the Ministry of Digital Affairs as part of the national AI strategy, which aims to ensure that Denmark has access to advanced and tailored language models. These models are intended for use across a wide range of sectors, including healthcare, public administration, education, and private enterprise.

A shared digital environment

The DFM project brings together Danish universities, research institutions, and industry partners in a joint effort to establish new standards for ethically responsible and inclusive AI language technologies.

The project is a collaboration between Aarhus University, the University of Copenhagen, the University of Southern Denmark, and the Alexandra Institute. DeiC Interactive HPC – UCloud plays a vital role in this work by providing high data security, scalable computing power, and, not least, an accessible, secure, national cloud platform that enables collaboration among project partners.

“UCloud forms the foundation for an important step in research digitalisation, as the platform provides easy access to computing power, enabling scalable data analysis and modelling, while also offering a secure environment for handling sensitive data. The platform also facilitates collaboration across institutions and allows us to manage data access as needed. This is particularly relevant in the DFM project, which includes many partners participating at different levels.”
Postdoc Kenneth Enevoldsen

Data security and computing power

Because AI models are often trained on sensitive data, it is crucial that data processing complies with both GDPR and Danish security standards. UCloud is ISO27001-certified and specifically designed to meet both Danish and EU requirements for secure data handling.

“In the DFM project, we work with very large amounts of data from a variety of sources – including sensitive data that the models are trained on – and this places high demands on data security. That is why UCloud is such a valuable tool for the project – precisely because of its high level of data security and access to scalable computing power.”
Postdoc Kenneth Enevoldsen

Although DFM also makes use of European supercomputers such as LUMI in Finland and Leonardo in Italy, the day-to-day operations of the project are heavily reliant on UCloud. In addition to being a springboard for high-performance computing, UCloud also provides a secure and user-friendly platform with a wide range of accessible applications – all essential for daily research, collaboration, data processing, and innovation across the project’s interdisciplinary team.

Critical infrastructure for Danish AI development

DFM’s principal investigators, Kristoffer Nielbo and Peter Schneider-Kamp, emphasise that the robust digital research environment provided by DeiC Interactive HPC – UCloud constitutes critical infrastructure. It streamlines workflows, enhances collaboration, and accelerates the development of both language and AI technologies.

“Without UCloud, the DFM project would have had to develop this type of digital infrastructure itself – with significant time and financial costs. The platform’s role in the project clearly demonstrates how robust, collaborative digital research environments are essential to Denmark’s AI strategies.”

Danish Foundation Models (DFM) is a collaborative project involving Aarhus University, the University of Copenhagen, the University of Southern Denmark, and the Alexandra Institute.

The project is supported by the Ministry of Digital Affairs with a grant of DKK 30.7 million and aims to develop advanced language models with open access and transparent development processes.

The models are specifically tailored to Danish and other Scandinavian languages and cultures and are intended for use across sectors such as healthcare, public administration, education, and business.

DFM seeks to establish a new standard for ethically responsible, inclusive, and transparent AI language technology – for the benefit of both Danish society and the research community.
