Copilot Narrative Visual in PowerBI
Hi Rohit_Singh_VC ,
At this time, report authors don’t have any control to check how the backend Copilot model is updated or to change how the Narrative visual behaves internally. The formatting style like paragraph format or structured tables,bullets is fully controlled by the Microsoft‑hosted Copilot service.
Sometimes, when Microsoft updates the service or adjusts model routing, the format may temporarily change on its own. That’s why the behavior sometimes goes back to normal even when you didn’t change anything in the report or prompt.You can try giving prompts that encourage structured output, but they cannot guarantee it every time. If this formatting issue starts happening again for many users, you can raise a support ticket with Microsoft Support so they can review this behavior from backend and assist you further.
If the issue continues, the support team will be able to investigate and guide you accordingly.

Hi Rohit_Singh_VC,
Thank you for reaching out to the Microsoft fabric community forum.
This looks like a change in Copilot behavior and not an issue with your report or prompt. The Copilot Narrative visual does not guarantee a fixed output format, and the response style can vary even if you clearly ask for bullets or structured output. Since the narrative format is controlled by Copilot, prompt instructions may not always be followed, especially after backend updates. A few other users have noticed the same behavior recently, which suggests this is not isolated to one report.
At the moment, there is no documented setting or workaround to force the narrative visual to always return structured or tabular output.
Kindly refer to the below documentation links for better understanding:

Hi and thanks for the information.
As it was working before, could you pls try to look into this to see if we can make to model to give structured output when the prompt says so, basically investigating the recent updates in the Model and making necessary adjustments/refinements to make it work, as earlier.
I have tried with simpler prompts. The current challenge is that the model results do not force the response to be formatted even after putting strict formatting instructions, which makes the results honestly like a big sintences of words put together in a paragraph and reduces readability. In turn reduces the usability of the visual as of now.
