SOVEREIGN AI WITHOUT COMPROMISE: ANNOUNCING THE AVAILABILITY OF MANAGED MODEL-SERVING AND INFERENCE CAPABILITIES ON PREMI3NS

Published on 11/05/2026

Regulated French enterprises, public institutions, and vital national operators (OIVs) have historically faced a difficult choice: compromise on data custody to adopt modern AI, or compromise on innovation to maintain sovereignty.

S3NS resolves this trade-off. We combine hyperscaler-level AI performance with French operational custody, conforming to French and European legal protections under the SecNumCloud 3.2 qualification.

Today, I am pleased to announce the General Availability of managed AI model-serving and inference capabilities on PREMI3NS, establishing a foundational layer of Gemini platform.

Building on the momentum of our exclusive early access program with select AI-forward organizations, we are thrilled to make these managed AI capabilities universally available across PREMI3NS. With today's announcement, you no longer have to struggle with running complex AI workloads in on-premises datacenters. By leaving the underlying infrastructure management to the experts at S3NS, your organization can focus on applying AI to engineer solutions for your hardest business problems.

We keep your data safe and sovereign within a hyperscale environment, backed by the freedom of open model choice. Whether you run real-time inference on models from leading providers like Mistral and Google, or bring your own custom fine-tuned weights, everything operates entirely within European jurisdiction. These new capabilities execute directly on our SecNumCloud 3.2-qualified infrastructure. In keeping with our commitment to certify every layer of PREMI3NS to the highest standard, the formal notification (J0) to extend our existing SecNumCloud qualification to this managed AI service layer has been submitted to ANSSI and is actively underway.

New AI Services on PREMI3NS

Gemini adds three foundational AI capabilities to PREMI3NS, taking our sovereign AI portfolio to a new dimension and setting the stage for continuous expansion:

Model garden on PREMI3NS is a dedicated portal for accessing and immediately deploying curated open-weight models, including Mistral and Google models alongside an expanding catalog of in-demand models from top AI providers. By running these workloads entirely within the PREMI3NS perimeter, your prompts and responses automatically inherit the robust security and protections against extraterritorial interference provided by SecNumCloud.
Model registry provides a central repository to govern the lifecycle of your organization's models. Teams can also import their own proprietary models that have been fine-tuned on domain-specific datasets and manage them with strict version control.
Online inference in Gemini connects your curated AI models directly into your applications. Because all interactions flow through our isolated network and infrastructure rather than the public internet, your organization can power real-time, AI-driven workflows while keeping sensitive corporate data protected.

Unlocking Business Value: Real-world Sovereign AI Solutions

Deploying AI with Gemini on PREMI3NS allows regulated organizations to drive business value while meeting their sovereignty requirements. Some examples include:

Insurance | Claims Processing and Triage: Unstructured claims documents contain personal data protected under GDPR. Insurance providers can deploy Mistral or Gemma models via model garden to automate claims triage while keeping all policyholder records inside the secured PREMI3NS perimeter.

Financial Services | Quantitative Risk and Fraud Intelligence: Financial institutions can import proprietary fraud-scoring weights into model registry and use these models to enable real-time transaction evaluation without exposing proprietary model weights or transaction telemetry.

Critical Infrastructure and Utilities | Operational Resilience: Energy grid and utility operators can deploy open-weight models and serve them via online inference to analyze sensor telemetry and detect grid anomalies before they cause outages. By keeping this critical analysis within the secure PREMI3NS perimeter, operators can help ensure greater physical resilience of their infrastructure, while generating compliant audit logs for regulators.

Healthcare | Clinical Administration: Healthcare institutions can import open-weight models, fine-tuned on regional datasets, into model registry and serve them via online inference. Clinicians can use these to automatically generate discharge summaries or parse unstructured medical notes, saving hours of administrative work while patient records remain protected.

A Scalable Foundation for Sovereign AI

Sovereign AI is ultimately about harnessing the power of AI to transform your business without sacrificing autonomy. By deploying on the managed model-serving foundation on PREMI3NS, your organization can accelerate innovation while maintaining full control. Standardizing on consistent APIs across open-weight and custom models prevents vendor lock-in and protects your intellectual property within secure endpoints. This release establishes a robust foundation for enterprise AI transformation, paving the way for frontier models and capabilities in upcoming phases.
