Power BI Copilot Now Accepts 10,000-Character Prompts. That’s Not the Upgrade That Matters.
TL;DR
Previously, Microsoft Power BI Copilot had a character limit of 500, restricting user input. In February 2026, Microsoft increased this limit to 10,000 characters, allowing for more detailed queries.
✦ Why It Matters
Engineers can leverage the expanded input limit to create more complex and informative data queries in Power BI.
Key Takeaways
- Utilize the expanded character limit for complex queries.
- Encourage detailed user input for better insights.
- Explore new data analysis techniques with richer prompts.
- Train users on effective query formulation.
Full Summary
Power BI Copilot is a tool that assists users in generating insights from data using natural language prompts. Before February 2026, users were limited to 500 characters, which constrained the complexity of queries they could make.
Microsoft addressed this limitation by increasing the input capacity to 10,000 characters, enabling users to provide more context and detail in their requests. This upgrade allows for richer interactions and more nuanced data analysis.
The change was implemented across all surfaces of Power BI, ensuring consistency in user experience. As a result, users can now explore data more comprehensively, leading to potentially better decision-making.
This enhancement is particularly significant for data analysts and business intelligence professionals who rely on detailed queries to extract insights.
