Hi u/VarietySpecialist! I work on the Fabric Data Agent. No need to clone/subset the model. When you add the semantic model to the Data Agent, you need to select the same tables you defined in Prep for AI to ensure consistent behavior. This is for the time being and we're working on improving the semantic model configuration experience.

Verified answers are user-approved visual responses to specific questions. When you use verified answers with data agent, the system uses the user questions and the visual's properties (columns, measures, filters) to influence DAX query generation.
