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](mailto: [email protected]). 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.

Create an access token

Authentication to access your personal fine-tuned models in handled via bearer token. To create a token, click on your user name in the top right corner of the AI Model Studio web UI and navigate to Organizational Settings. API tokens will be created in the API Keys tab.

Note: As the AI Model Studio Beta is not fully integrated into the DCD ecosystem, IONOS Cloud API tokens created within the IONOS DCD cannot be used for accessing the Model Studio API. You must generate tokens directly within AI Model Studio to access its API.

Endpoints

Best Practice: You can generate ready to use code for API calls to your model within the AI Model Studio. Go to the Models section inside the web UI, select the model you want to use, and click on <>.
