EU AI deployment is what you need when the answer to “can this leave” is no. Ireland sells into the rest of the Union and hosts a large share of its data, so the question arrives early here.
It is an engineering choice with real trade-offs, and we measure them before anything is bought.
What Forces an EU AI Deployment
A contract clause naming the location. The common one. Where the clause says the data stays inside the Union, this is what satisfies it.
Client material held under privilege or NDA. Usually written before anybody was thinking about language models, and usually broad enough to cover them.
Sectoral rules. Health, financial services and public sector work each carry constraints stricter than general data protection.
Volume economics. At steady high throughput a model you host costs a fraction of the same work billed per call, and the crossover arrives earlier than most people expect.
Where a hosted model in an EU region is the better decision, we will say so and build that.
Three Places Your Text Goes
In a typical system three components touch your text: whatever stores the documents, whatever computes the embeddings, and the model that generates the answer.
All three get a named region, agreed at scoping and written into the architecture note. A model endpoint in an EU region is a different guarantee from a model whose provider cannot read the traffic, and which one your contract requires decides the architecture.
That note is also the evidence base the EU AI Act rewards, and your advisers can read it without translation. We build to the constraint they set.
What It Involves
A model sized to the hardware, not the headline. Most commercial work runs on far less than the marketing suggests.
Quantisation with the trade measured. Smaller precision is faster, cheaper and slightly worse, and how much worse has an answer specific to your task.
Serving that degrades sensibly. Batching, concurrency, a queue, and monitoring that reports saturation before failure.
A cost model from measurement. Hardware, power and engineer time against the hosted bill for the same volume, produced before you commit. That figure usually decides the project, so it arrives first rather than last.
What Open Models Are Genuinely Good At
Extraction, classification, summarisation and retrieval over your own documents, which covers most commercial work.
For those tasks the residency requirement wins comfortably, and any EU AI deployment decision should rest on the measured number for your task. That is what AI evaluation produces.
The weights, the serving configuration, the evaluation set and the runbook are yours, so your own team can operate it. Support runs business hours with a named engineer who knows the estate. Tell us what the data is and which rule applies.
