AI Model Studio for Free: AI Model Studio is available as a free beta offering in the German market from October 1 through December 30, 2025. Register today to fine-tune your first AI model.´
Attention: The AI Model Studio is a free beta. Breaking changes and limited availability of features may occur at any time. It is developed in cooperation with our partners at manufactAI and is based on their innovative fine-tuning solutions. While the service runs entirely on IONOS Cloud infrastructure, our partners manage it at manufactAI, and support for the service is only provided through contacting manufactAI. This service does not accept IONOS Cloud API tokens and log-in credentials.
The AI Model Studio can be used for inference tasks through API to be integrated into AI applications or for running more sophisticated evaluations. The following paragraphs explain how and which specifications the API can access.
