June 2026

This month, we’re continuing to focus on making every day work a little easier—whether that’s building reports, modeling data, or just getting answers faster. You’ll see progress across Copilot and newer AI-driven experiences, along with a set of practical updates to reporting that help reduce repetitive work.

AI powered Power BI reporting skills is a collection of multiple skills that enables AI agents to automate report creation, from designing pages to publishing to Fabric. Now available through the Power BI authoring plugin  in Skills for Fabric —a first-party catalog of agent skills for Microsoft Fabric optimized for GitHub Copilot CLI—this capability allows agents to author reports through natural language, write schema-correct PBIR files, reload Power BI Desktop, capture screenshots, and iteratively refine reports for a seamless, end-to-end authoring experience.

Copilot in web modeling (Preview) in the Power BI service, is an AI-powered assistant helping you analyze and improve your semantic models using natural language so you can spend less time on manual edits. 

Microsoft Build 2026 marks a major shift in how developers build data experiences with AI agents. Today we’re announcing two capabilities that bring agentic analytics to the forefront: Agent Skills for Power BI, which let developers prompt an AI agent to build and refine semantic models and reports, and Fabric Apps for Semantic Models, which enable AI agents to build and deploy Fabric-native web apps on semantic models. Both capabilities will accelerate the time it takes to go from raw data to a polished analytics solution with just natural language prompts.

Microsoft Build 2026 brings the next generation of intelligent analytics to Power BI—where agents do the building, apps deliver insights everywhere, and the platform gets more powerful for every user.

Frontier Tuning introduces a new way to tune AI agents around your organization’s workflows, internal knowledge, and compliance safeguards.

The post Frontier Tuning: Teaching AI to work the way you do appeared first on Microsoft Copilot Blog.

DAX user-defined functions are now production-ready based on community feedback and internal validation. Their adoption during preview shows that DAX UDFs are quickly becoming a mainstay of Power BI semantic models.
