Hello @Nathanael Santschi , Thanks for using Microsoft Q&A Platform.
The Azure AI Services resource and the Azure AI Services multi-service account are two different ways to create multi-service Azure AI resources.
As per my knowledge, the main difference between the two is that the Azure AI Services resource is a newer option that allows you to create a single resource that can access multiple Azure Cognitive Services with a single key and endpoints for the respective service. On the other hand, the Azure AI Services multi-service account is an older option.
Using Azure AI Services multi-service account only one endpoint is created, for example: https://multiserviceresource.cognitiveservices.azure.com/
However, using Azure AI Services resource different endpoints for the respective service is created as shown here in the example:
I hope this helps.
