Which models can we use?

Every frontier model in one interface: Anthropic, OpenAI, Google, Mistral, xAI, DeepSeek and Qwen. That is 24 models today, 16 of them with an EU-hosted variant, and open-weight models can run on your own GPUs.

What happens to sensitive data in a prompt?

Compliance rules run before a prompt leaves your tenancy. Templates such as BSI IT-Grundschutz or GDPR Art. 9 block or replace data like IBANs, phone numbers and VAT IDs, and every match is written to the audit log.

How does oneAI help with the EU AI Act?

The Compliance Copilot rates every request by EU AI Act risk level, and you decide what happens at each level. Each audit log entry carries that level and can be exported for your auditor.

Do you sign a data processing agreement?

Yes. A data processing agreement under Art. 28 GDPR is part of the contract, and operations are certified to ISO 27001, 9001, 14001 and 42001.

Sovereign AI operating system

Every frontier model. None of the exposure.
