STACKIT AI Model Serving: sovereignty score and 8 European alternatives

AI Model Serving is a service within STACKIT's Data and AI platform that gives companies API access to large language models; the product page names Llama 3.1 as an example. Organisations connect their own chatbot or application to a model of their choice and can add company data through an open-source RAG template. Usage is billed per token, and the service runs on the STACKIT cloud rather than as software to install.

STACKIT is operated by Schwarz Digits Cloud GmbH & Co. KG, part of the Schwarz Group in Germany, which describes itself as independent of external investors. STACKIT states that customer data is hosted exclusively in Europe and that its services are GDPR-compliant. The product page states that data and queries are neither stored nor used to train models; this is the provider's own statement. STACKIT describes itself as a European hyperscaler, so for a European organisation it is a Europe-hosted alternative to the model services of US hyperscalers.

Why digital sovereignty matters with STACKIT AI Model Serving

STACKIT AI Model Serving is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

STACKIT AI Model Serving is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs STACKIT AI Model Serving together with your other vendors and gives a total score, a heatmap and the main risk drivers.
