What it does EU Router

Why LLM inference in the EU

Serving a language model to real users is a different job than running one on a laptop. Production inference means concurrent requests, streaming tokens, predictable capacity and a clear view of what every request cost you. HostYourAI runs open models such as Llama, Qwen, Mistral and DeepSeek with vLLM on European GPUs, exposed through an OpenAI-compatible API, so your application code barely changes.

Where that inference happens matters. Every prompt your users send is data, and often personal data. Keeping inference in European datacenters, backed by a Data Processing Agreement and a public subprocessor list, turns a compliance headache into a checkbox you can actually tick.

01

Prompts are personal data

Support tickets, medical notes, contract clauses: whatever your users type ends up in a prompt. Under the GDPR you are accountable for where that text is processed. Inference that never leaves multiple European regions keeps your data flow map short and your DPA meaningful. HostYourAI does not train on customer data, and traffic is encrypted with TLS in transit and AES-256 at rest.

02

Latency lives close to your users

Round trips to another continent add delay to every token of a streamed response. For chat interfaces, where perceived speed is the time to the first token, serving from European GPUs to European users simply feels faster. Popular models on the shared Router are kept warm through a warm pool, so requests do not wait for a cold model to load.

03

Cost control without lock-in

Inference bills are notoriously opaque. HostYourAI uses one prepaid credit balance, topped up with iDEAL, card or SEPA, and every request is metered so you can see usage per key. Because the API is OpenAI-compatible, moving in or out is a base URL change, not a rewrite. Details are on the pricing page.

What makes inference production-ready

Three things separate a demo from a service. First, streaming: the API supports server-sent events on /v1/chat/completions, so tokens reach your UI as they are generated. Second, capacity: the shared EU Inference Router pools demand across a warm fleet, while dedicated GPU instances give you a vLLM server of your own, with an encrypted API key and a VRAM floor that prevents deploying a model onto a GPU that is too small. Third, observability: per-request usage records and a 99.9% uptime SLA, so you know both what happened and what to expect.

How to start

Create an API key, pick a model from the model catalog, and point your existing OpenAI client at the new base URL. This JavaScript example streams a response from Llama 3.3 70B:

javascript
import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://hostyourai.com/api/v1",
  apiKey: "hyai-...",
});

const stream = await client.chat.completions.create({
  model: "llama-3.3-70b",
  messages: [{ role: "user", content: "Summarize this ticket for the support team." }],
  stream: true,
});

for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? "");
}
Questions

Questions about LLM inference

Which models can I run?

The catalog lists over 700 open models, including Llama, Qwen, Mistral, DeepSeek and Gemma. The Model Garden shows the state of each one: warm, warming up, serveable, or on request.

Do I need to change my application code?

Usually only the base URL and API key. The API is OpenAI-compatible, and there is also an Anthropic-compatible /v1/messages shim for code written against that SDK. See the guide to migrate your OpenAI client to the EU Router.

Shared Router or dedicated instance?

The Router bills per token and suits variable workloads. A dedicated instance bills per minute, gives you isolated capacity, and stops billing the moment you delete it. Both draw from the same prepaid credit balance.

How fast is a cold model?

Popular Router models are kept warm, so there is no load time. Less common models may show as warming up in the Model Garden while vLLM loads the weights.

Is streaming supported?

Yes, /v1/chat/completions supports SSE streaming exactly as the OpenAI API does. Set stream to true and consume the chunks.

Where does my data go?

Inference runs in European datacenters across multiple European regions. HostYourAI provides a DPA, publishes its subprocessor list, and never trains on customer data.
