IONOS AI Model Hub
The IONOS AI Model Hub is a sovereign inference API that runs open-weight LLMs and image models entirely on German infrastructure. Operated by IONOS — Germany's largest hosting provider — it targets companies that need GDPR-grade data residency without giving up an OpenAI-compatible developer experience.
All processing happens in IONOS data centres, with prompts "securely stored in a database in our Berlin data center" and discarded after each session, "free from logging, recording, or reuse for model training". The platform carries ISO 27001 and Gaia-X certifications and is designed to comply with the GDPR.
The catalogue covers open-weight models such as Llama 3.1 (8B–405B) and Mistral, exposed through an OpenAI-compatible REST API, so teams can switch a single credential to move off US infrastructure. Billing is pay-per-token. For most German SMBs it is one of the most accessible entries into sovereign AI, sitting between hyperscaler scale and specialists like Aleph Alpha.
