First complete Swiss end-to-end solution for sovereign AI
Phoenix Technologies hosts Apertus LLM, creating the first complete end-to-end solution for sovereign AI in Switzerland. This marks a milestone that provides Swiss companies with secure, high-performance access to a transparent open source AI model and ensures complete data sovereignty and compliance.

Phoenix Technologies AG, a leading provider of sovereign cloud and AI infrastructure in Switzerland, announced the availability of Apertus on its sovereign cloud. Developed by EPFL, ETH Zurich and the Swiss National Supercomputing Center (CSCS), Switzerland's first open and transparent Large Language Model (LLM) can now be deployed on Phoenix Technologies' high-performance infrastructure. This milestone strengthens Switzerland's digital autonomy and establishes the country's first end-to-end sovereign AI solution, according to the statement.
Data is completely subject to Swiss law
According to the company, for the first time, Swiss organizations in sensitive sectors such as finance, healthcare and government can use a state-of-the-art LLM without their data ever leaving Swiss jurisdiction. This approach directly addresses the critical innovation needs of organizations while mitigating the risks associated with foreign AI platforms. It provides a trusted pathway for companies looking to harness the power of generative AI while fully complying with Switzerland's strict data protection standards.
"This is a declaration of Switzerland's digital independence," said Thomas Taroni, Executive Chairman and Founder of Phoenix Technologies. "For too long, Swiss companies faced a difficult choice: either innovate with foreign AI and risk data sovereignty or fall behind. Today, this decision is outdated. By combining the Apertus model with our sovereign, high-performance infrastructure, we offer the definitive Swiss answer to AI. We are empowering entire industries to build the future on a foundation of trust, security and Swiss values."
Advanced safety functions
The technical basis of the solution combines fully open-source AI with Phoenix Technologies' enterprise-grade infrastructure. Apertus is available with up to 70 billion parameters and is characterized by its fully documented development process and multilingualism. This model runs on Phoenix's cloud platform powered by next-generation NVIDIA H100 and H200 enterprise-grade GPUs. The platform is equipped with advanced security features, including Confidential Computing, which protects data not only at rest and in transit, but also during processing, ensuring an unprecedented level of security for sensitive workloads.
Available immediately
The Apertus model can now be provided via the "AI Model as a Service" and "Sovereign LLM Serving" services from Phoenix Technologies. Interested companies can contact Phoenix Technologies for advice.
