Frequently asked questions
Can I run Qwen 3 4B in the EU?
Yes. HostYourAI runs Qwen 3 4B on GPUs in European datacenters via vLLM. Prompts and outputs never leave the EU and there is no US cloud provider in the chain.
Is hosting Qwen 3 4B GDPR-compliant?
Yes. All processing happens inside the EU, a Data Processing Agreement (DPA) is available and the subprocessor list is public. Open-source weights also mean: no training on your data.
How much does Qwen 3 4B cost?
Via the shared EU router you pay €0.03 per million input tokens and €0.06 per million output tokens, with no fixed costs. For high volume or isolation you can also run Qwen 3 4B as a dedicated hourly GPU instance.
Is the API OpenAI-compatible?
Yes. You use the standard OpenAI SDKs with a custom base URL (https://hostyourai.com/api/v1). The Anthropic Messages API is supported as a drop-in as well.
