ChatGPT functionality, EU infrastructure
Want the capabilities of ChatGPT without sending your data to a US service? With HostYourAI you build chat functionality on open models that run on European GPUs. The API is OpenAI-compatible, so tools that expect OpenAI work right away.
Why European businesses choose open models
- Data residency inside the EU, no US cloud in the chain
- Open weights you can audit
- No training on your prompts or data
- Data Processing Agreement available
From prototype to production
Test models in the Playground, deploy them through the Router or a dedicated instance, and track usage per request. That is how you go from experiment to a production API that runs entirely in Europe.
How to switch
Migrating does not take weeks. Your existing OpenAI SDK keeps working: set the base URL to our Router and use your HostYourAI key.
from openai import OpenAI
client = OpenAI(
base_url="https://hostyourai.com/api/v1",
api_key="hyai-...",
)
resp = client.chat.completions.create(
model="llama-3.3-70b",
messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)Pick an open model from the Model Garden, test in the Playground and track usage and cost per request. For a step-by-step walkthrough, read the guide Migrate your OpenAI client to the EU Router.

Questions about the ChatGPT alternative
Can my team chat with it like ChatGPT?
Yes, in two ways: directly in the Playground, or through a chat interface you connect to the API. Any chat UI that supports an OpenAI-compatible API, such as Open WebUI, connects with a base URL and key.
Is an open model as good as ChatGPT?
For most everyday tasks, such as writing, summarising and answering questions about documents, modern open models perform strongly. Compare for yourself in the Playground; you only pay the test tokens.
What does this mean for privacy?
Everything runs on European GPUs: prompts and answers never leave the EU, there is no training on your data and a Data Processing Agreement is available.
What does it cost compared to a ChatGPT subscription?
No fixed amount per user: you pay per token from one prepaid balance. With light or variable use that is usually cheaper; see the pricing page.
Can it read my own documents?
Yes. Link a knowledge base and answers are grounded in your own sources. Read the guide Build RAG on EU GPUs.
How do I start?
