Frequently asked questions

Can I run GLM 4.5 Base in the EU?

Yes. HostYourAI runs GLM 4.5 Base 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 GLM 4.5 Base 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 GLM 4.5 Base cost?

Via the shared EU router you pay €0.40 per million input tokens and €0.60 per million output tokens, with no fixed costs. For high volume or isolation you can also run GLM 4.5 Base 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.
