AI Data Sovereignty
Full control over where and how your AI data is processed.
Data sovereignty is often sold as a sticker: an EU flag on a pricing page. Real sovereignty is a stack of separate questions, and a vendor can pass one layer while failing the next. A US hyperscaler with an EU region passes the infrastructure test and fails the jurisdiction test. A European reseller of a closed US model passes jurisdiction and fails the model test.
HostYourAI was built to answer all four layers at once: a Dutch company serving open-weight models from European datacenters, with contractual guarantees about what happens to your data. Here is how to evaluate any vendor, including us, layer by layer.
Why data sovereignty in the EU
Jurisdiction outranks geography
The CLOUD Act reaches data held by US companies wherever the servers stand, so "hosted in Europe" by a US provider does not settle the legal question. Sovereignty starts with who can be compelled, not where the rack is. HostYourAI is Dutch, from Groningen, and the serving chain contains no US cloud provider.
Dependence is a strategic risk, not just a legal one
Terms change, models get deprecated, prices move, export rules shift. European organisations that build on closed foreign APIs inherit all of that volatility. Open weights on European infrastructure keep the option to move, self-host or renegotiate.
Regulators are converging on the same questions
GDPR enforcement, the EU AI Act and national procurement rules all push toward documented, EU-resident processing. Answering the four layers below well today is preparation for every one of those frameworks tomorrow.
The four layers of sovereignty
Layer one is jurisdiction: which legal system can compel access to your data? For HostYourAI the answer is EU law, because the operator is Dutch and no US cloud sits in the serving chain, which removes CLOUD Act exposure. Layer two is infrastructure: where do the GPUs physically run? In multiple European regions, whether you use the EU Inference Router per token or dedicated GPU instances per hour. Layer three is the model: can you inspect what you depend on? Every model in the model catalog is open-weight (Llama, Qwen, Mistral, DeepSeek, Gemma), so the weights and licence are auditable and portable. Layer four is the data itself: what happens to your prompts? They are never used for training, a DPA fixes that contractually, the subprocessor list is public, and everything is AES-256 encrypted at rest with TLS in transit. Miss any single layer and the other three cannot compensate.
| Layer | Question for any vendor | HostYourAI answer |
|---|---|---|
| Jurisdiction | Which law can compel disclosure? | EU law; Dutch operator, no US cloud in the chain |
| Infrastructure | Where do the GPUs run? | European datacenters, multiple regions |
| Model | Can we inspect and move the model? | Open weights only, auditable and portable |
| Data | Are prompts reused or trained on? | Never; DPA, public subprocessors, AES-256 and TLS |
How to start
Sovereignty should not cost you a rewrite. The endpoint is OpenAI-compatible, so switching is a two-line change, as shown in Migrate your OpenAI client to the EU Router.
from openai import OpenAI
client = OpenAI(
base_url="https://hostyourai.com/api/v1",
api_key="hyai-...",
)
resp = client.chat.completions.create(
model="deepseek-v3",
messages=[{"role": "user", "content": "List the four layers of AI data sovereignty."}],
)
print(resp.choices[0].message.content)from openai import OpenAI client = OpenAI( base_url="https://hostyourai.com/api/v1", api_key="hyai-...") client.chat.completions.create( model="llama-3.3-70b", messages=[{"role":"user","content":"Hallo!"}])
Questions about data sovereignty
Is an EU region of a US cloud sovereign?
Not fully. The infrastructure layer is European, but the jurisdiction layer is not: US law can still reach a US company's data regardless of server location.
Why do open weights matter for sovereignty?
Because you can audit exactly what you run and take it with you. A closed API can change or disappear; open weights served with vLLM can move to another provider or your own hardware.
What guarantees cover my prompts?
A DPA covering EU processing, a public subprocessor list, and a contractual commitment that customer data is never used for training. Encryption is AES-256 at rest and TLS in transit.
Does sovereignty mean giving up modern tooling?
No. The API is OpenAI-compatible and also offers an Anthropic-style /v1/messages shim, so existing SDKs, frameworks and RAG pipelines keep working.
Which sectors ask for this most?
Anywhere procurement or regulators demand documented EU processing: see the pages for government and finance for sector specifics.
Everything you need for AI
From model hosting to a customer-facing API, it is built for developers and businesses who want their AI running on infrastructure they actually control, inside the EU.
Your data and your models stay on European GPUs. GDPR-friendly by design.
Llama, Qwen, DeepSeek, Mistral, FLUX and plenty more. Pick one and it is warm in minutes, with no DevOps on your end.
Point your existing client at the Router and keep your tools. No rewrite, no lock-in.
From zero to a warm endpoint in minutes
No infra to manage. Pick a model, get an OpenAI-compatible URL, ship.
Pick a model
Choose from the Model Garden or paste any HuggingFace ID. Set the VRAM and pick an EU GPU.
Get your endpoint
We deploy vLLM, run readiness probes, and hand you a warm OpenAI- and Anthropic-compatible URL plus an API key.
Route and ship
Point your client at the Router. It auto-routes to a warm instance, idles GPUs when nobody is online, and logs every request.
Works with the tools you already use
The Router speaks the OpenAI and Anthropic APIs, so it drops straight into the clients and SDKs your team already runs. Just change the base URL.

Frequently asked questions
Can I run this in the EU?
Yes. HostYourAI runs open models on GPUs in European datacenters via vLLM. Your prompts and outputs never leave the EU and there is no US cloud provider in the chain.
Is it GDPR-compliant?
Yes. All processing happens inside the EU, a Data Processing Agreement (DPA) is available and the subprocessor list is public. Open weights also mean no training on your data.
Is the API OpenAI-compatible?
Yes. Point your existing OpenAI or Anthropic client at our Router (https://hostyourai.com/api/v1), change only the base URL and API key. No rewrite, no lock-in.
What does it cost?
Pay-as-you-go on one prepaid credit balance: the shared router per token or a dedicated GPU per hour. Free to start, no minimum, no fixed monthly fee.
Works with 390+ open models
Text and image models on dedicated EU GPUs. Every model tested on our own hardware.
