Sovereign AI
Definition
A politically loaded umbrella term for AI infrastructure under national or European control — across the layers of data, operations, models and training data. There is no single technical definition.
Noise — Signal
"Sovereign" is used by vendors in at least three very different meanings: first as data residency (the data stays in the EU), second as hosting sovereignty (the infrastructure is operated by a European provider), third as full control over model, weights and training data. Only the third is real sovereignty. The first two are useful but not sovereign if model updates, licence terms or the training pipeline remain under the control of a non-European actor. This distinction is rarely flagged in vendor decks.
The right question
Not: "Is this solution sovereign?" But: "On which of the three layers — data, operations, model — do we actually have control, which remains a dependency, and which of those dependencies is manageable in a crisis?"
