In detail
What European AI tools do differently
With AI services, what matters is where models are hosted and where inputs and training data flow. The CLOUD Act requires US providers to hand over data to US authorities, even when servers are located in Europe. Providers such as Mistral AI, Aleph Alpha and DeepL run inference and models on European infrastructure and operate under GDPR. Some offer open-weight models or allow on-premise and private cloud deployments, where model weights and inputs stay within your own data center.

Frequently Asked Questions
Why does server location matter for AI services?
With AI services, inputs, documents and in part training data are transmitted to the provider. The CLOUD Act allows US authorities to demand that US companies hand over this data, regardless of where it is stored. Providers such as DeepL, Mistral AI and Aleph Alpha process inference on European infrastructure and are subject exclusively to GDPR.
Which providers allow on-premise or private cloud deployment?
Aleph Alpha and its PhariaAI platform are explicitly designed for sovereign deployments and can be installed in your own data center or a private cloud. Mistral AI offers on-premise deployments and open-weight models that can run in your own infrastructure. Nebul additionally provides an optional on-premises AI pod for sensitive data. In these cases, model weights and inputs stay within the chosen environment.
Are all providers listed here fully independent of US cloud?
No. Mistral AI, Aleph Alpha, DeepL, Nebul and Helsing run inference on European or self-operated infrastructure. Others use US hyperscalers depending on configuration: Dust runs on Google Cloud (with EU regions), Celonis on AWS and Azure with selectable EU locations, Ada Health on AWS in the EU. The individual product pages describe the specific infrastructure in detail.
What do open-weight models mean for data protection?
Open-weight models such as parts of the Mistral portfolio are published under open licenses and can be downloaded and run in your own infrastructure. As a result, inputs do not leave your own system, and there is no lock-in to a single provider. Aleph Alpha pursues a similar sovereignty approach with its Luminous and Pharia models for regulated environments.
Which AI tool fits which use case?
DeepL covers machine translation, while Mistral AI and Aleph Alpha provide language models and LLM platforms. For AI agents connected to corporate data sources, Dust and ChatBotKit are suitable; for GPU infrastructure and model training, Nebul. Celonis addresses process intelligence, Ada Health the medical symptom check and Helsing the defence sector. The choice depends on the task, the required data residency and the desired deployment model.
