OneNext 2025
Building the AI Continent Together
Defining the Open Technology Stack for Sovereign AI Factories & Gigafactories
NOVEMBER 12-13, 2025
MIX BRUSSELS, BELGIUM
What is OneNext 2025?
OneNext 2025 will bring together leading industry stakeholders driving the development of sovereign AI Factories. The event will explore the key challenges in building the next generation of open, decentralized AI Factories and Gigafactories, leveraging HPC, cloud, and edge infrastructure as a strategic alternative to proprietary hyperscaler solutions. Building on the legacy of the OpenNebulaCon series, the 2025 edition will focus on how open cloud technologies are powering sovereign cloud environments and enabling next-generation AI Factories at scale.
The agenda will span all layers of the technology stack, bringing together the industrial ecosystem of the IPCEI-CIS initiative, the AI Factory efforts within EuroHPC, and key stakeholders from the cloud and telecom sectors. The program will feature thematic panels with C-level executives, directors, and leading experts who are shaping the AI and cloud infrastructure landscape, aiming to generate actionable recommendations for both industry and public-sector stakeholders. A final report will consolidate the collective outcomes of the event, ensuring anonymity and avoiding direct attribution of individual contributions.

AGENDA HIGHLIGHTS
The event aims to address the critical need for a high-performance, distributed HPC-cloud-5G/edge continuum infrastructure that can support the growing demands of AI workloads and ultra-low-latency applications. We will discuss:
Scaling LLMs at Infrastructure Level
Challenges in the execution of large language models (LLMs) and AI frameworks at scale, including performance optimization, distributed deployment, data locality, and interoperability across heterogeneous infrastructure.
Cloud-Edge AI Architecture
Architectural directions required to build a scalable and diverse cloud-edge computing ecosystem, capable of supporting the full AI lifecycle—from training and fine-tuning to inference—at scale.
5G & AI Continuum Connectivity
Connectivity requirements across this continuum, including the role of 5G and advanced networking, to ensure seamless workload distribution and real-time processing.
Sovereign AI Orchestration
Core components of a software platform needed for the orchestration and monitoring of AI workloads across heterogeneous HPC, cloud, and edge environments, with an emphasis on strategic sovereignty across layers.

INITIAL AGENDA
Industry Demand for Sovereign AI
Industry leaders discuss their real-world AI needs—performance, compliance, and operational integration—and how sovereign, open solutions can address these priorities.
The Open Large Model Landscape
Focus on the development and deployment of open source large language models, covering challenges in data, compute, alignment, and collaborative innovation.
AI Platforms and Workflows
Explores orchestration tools and software platforms that enable scalable AI workflows across hybrid environments, from training to inference.
The Software Stack Behind Sovereign AI Factories
An exploration of the core software components enabling sovereign AI infrastructures—from virtualization orchestration and infrastructure automation to scalable storage and AI inference tooling. This panel will address how these layers integrate to support secure, high-performance AI deployments across hybrid and edge environments.
Infrastructure Components for AI Factories
Exploring how next-generation hardware—CPUs, GPUs, accelerators, and interconnects—is shaping the performance, efficiency, and sovereignty of AI Factory deployments. The panel will address compute density, energy efficiency, hardware-software integration, and open hardware initiatives.
HPC for AI Factories
Discusses leveraging HPC to scale AI model training and fine-tuning, supporting hybrid architectures, and fulfilling performance/security needs for Sovereign AI.
Cloud Providers and AI
Highlights how cloud providers are adapting to support sovereign AI through accelerated hardware, enhanced data protection, and scalable infrastructure.
AI at the Telco Edge
Focuses on how telecoms are embedding AI into 5G networks, enabling edge intelligence, and reinforcing the telco role in sovereign, decentralized AI deployment.
