Semantic models leveraged by Copilot

[BindiyaThota]

Hi,

I just started to explore Copilot in Power BI. In service we have workspaces backed by fabric capacity. I have to select a report to view the Copilot button and then I am able to get answers on the scemantic model.

Is it possible for Copilot to consider all semantic models to answer questions?

Appreciate any suggestions. Thanks!

Hi @BindiyaThota ,
Thank you @lbendlin and @rohit1991 for the accurate response!

Your responses accurately explains how Copilot currently works within Power BI, specifically at the report level, leveraging the semantic model connected to the selected report. 

In addition to that, I would like to share the official documentation on how Copilot works with data in Power BI:
https://learn.microsoft.com/en-us/power-bi/create-reports/copilot-ask-data-question 

I hope this helps.If so, consider accepting it as solution.

Thank you for being a valued member in Microsoft Fabric Community Forum!

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.

At the moment you are limited to the currently active semantic model (and its lineage).

There can be hundreds of semantic models in a single workspace, and many thousands in a capacity. Including all of them likely doesn't make sense and can lead to security issues.
