High-performance LLM inference with vLLM in European data centers.
Ask two teams to serve the same open model on the same GPU and you can get wildly different throughput. The difference is usually the serving engine. HostYourAI runs every model, shared or dedicated, on vLLM: the open source engine that has become the de facto standard for LLM inference in production.
You get vLLM's efficiency without operating it yourself, on GPUs in European datacenters, behind an OpenAI-compatible endpoint. Prompts stay inside the EU, a DPA is available, and nothing you send is ever used for training.
The more requests a single EU-based GPU can handle, the less pressure there is to spill traffic to whichever cloud is cheapest that week. An efficient engine on European hardware keeps the whole path, network, GPU and logs, under GDPR-friendly jurisdiction.
vLLM streams tokens over SSE, and streaming makes distance visible: every chunk crosses the network. Serving European users from multiple European regions keeps that path short.
Version bumps, CUDA compatibility, memory tuning, health probes: self-hosting vLLM means owning all of it. Here that work is done for you, backed by a 99.9% uptime SLA, and if you want to understand the self-managed path first, read Deploy your own LLM with vLLM.
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!"}])
A GPU spec sheet tells you almost nothing about tokens per second under real traffic. Two mechanisms in vLLM do the heavy lifting. Continuous batching means the engine does not wait for a batch to finish before admitting new requests; as soon as one sequence completes, the next one slots in, so the GPU rarely sits idle between requests. PagedAttention manages the attention cache the way an operating system manages memory, in small pages instead of one big contiguous block, which sharply reduces wasted VRAM and fits more concurrent sequences on the same card. No made-up speed multipliers here; the practical effect is simply better utilisation per GPU-hour, whether you pay per token on the EU Inference Router or per hour on dedicated GPU instances. Popular models stay warm through the Router's warm pool, and each dedicated instance runs vLLM behind its own encrypted API key.
| vLLM term | What it means for you |
|---|---|
| Continuous batching | New requests join mid-flight, less idle GPU time |
| PagedAttention | Less wasted VRAM, more concurrent users per GPU |
| SSE streaming | Tokens appear as they are generated, chat feels responsive |
| OpenAI-compatible server | Your existing SDK and tools work unchanged |
| Warm pool | Popular Router models answer without a cold start |
| Per-instance API key | Your dedicated endpoint is encrypted and yours alone |
Pick a model from the model catalog and call it with the standard OpenAI SDK. Streaming works out of the box.
from openai import OpenAI
client = OpenAI(
base_url="https://hostyourai.com/api/v1",
api_key="hyai-...",
)
stream = client.chat.completions.create(
model="gemma-3-12b",
messages=[{"role": "user", "content": "Explain PagedAttention in one paragraph."}],
stream=True,
)
for chunk in stream:
print(chunk.choices[0].delta.content or "", end="")No. On the shared Router it is fully managed, and dedicated instances boot with vLLM configured for the chosen model, including a VRAM floor check so the GPU is never too small.
Yes, /v1/chat/completions with SSE streaming, and there is also an Anthropic-style /v1/messages shim with x-api-key auth for text-only, buffered-streaming use.
Loading model weights onto a GPU takes time. Popular Router models are kept warm in a warm pool, and the catalog shows each model's state: warm, warming up, serveable or on request.
Yes, on a dedicated instance. vLLM loads open-weight variants, so a fine-tune of Llama, Qwen or Mistral serves the same way as the base model.
Each instance has its own encrypted API key, traffic runs over TLS and data at rest is AES-256 encrypted. Instances also idle down when unused.

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.
No infra to manage. Pick a model, get an OpenAI-compatible URL, ship.
Choose from the Model Garden or paste any HuggingFace ID. Set the VRAM and pick an EU GPU.
We deploy vLLM, run readiness probes, and hand you a warm OpenAI- and Anthropic-compatible URL plus an API key.
Point your client at the Router. It auto-routes to a warm instance, idles GPUs when nobody is online, and logs every request.
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.
