Semantic models leveraged by Copilot

Hi BindiyaThota ,
In Power BI, Copilot currently works at the report level, meaning it leverages the semantic model that is directly connected to the selected report. At this time, Copilot does not support querying across multiple semantic models simultaneously.

When you select a report in a workspace backed by Fabric capacity, Copilot accesses the semantic model behind that specific report to generate insights or answer questions. If you need to reference data across multiple models, you'll either need to consolidate the data into a single semantic model or create a report that connects to a composite model designed to pull in data from different sources. Microsoft is continually expanding Copilot’s capabilities, so multi-model support may be introduced in future updates.
