Frequently asked questions

Can I run Cosmos Reason1 7B in the EU?

Yes. HostYourAI runs Cosmos Reason1 7B 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 Cosmos Reason1 7B 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 Cosmos Reason1 7B cost?

Via the shared EU router you pay €0.05 per million input tokens and €0.12 per million output tokens, with no fixed costs. For high volume or isolation you can also run Cosmos Reason1 7B 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.
