Claude API alternative
Keep your Anthropic SDK and run open models on European GPUs instead of the Claude API.
Anthropic-compatible, EU-hosted
Want to keep using the Anthropic API but keep your inference in Europe? HostYourAI speaks the Anthropic API through a /v1/messages shim. You point your existing client at our Router and run open models on European GPUs.
EU Inference Router
‹ Insight 1 of 28 ›What you get
- The
/v1/messagesshape withx-api-keyauthentication - Open models on EU infrastructure you control
- Also OpenAI-compatible through the same Router
- No training on your data; subprocessor list public
from openai import OpenAI
client = OpenAI(
base_url="https://api.hostyour.ai/v1",
api_key="hyai_...")
client.chat.completions.create(
model="llama-3.3-70b",
messages=[{"role":"user","content":"Hallo!"}])One platform for both APIs
If you run applications on both the OpenAI and the Anthropic API, you can do so through the same Router and the same EU GPUs. That keeps your stack simple and your data inside Europe.
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 100+ open models
Text and image models on dedicated EU GPUs. Every model tested on our own hardware.
