# Configuring Power BI Semantic Model AI Instructions A practical, reusable guide for configuring AI instructions on a semantic model. Use this template across projects — the example domain (retail / sales) is illustrative; replace it with your own without changing the structure. --- ## What semantic model AI instructions are A single text blob (up to 10,000 characters) attached directly to the semantic model. It provides context, business logic, and guidance that Copilot uses when interpreting user questions against the model. It applies **wherever the model is consumed by Copilot** — Power BI reports, Q&A visuals, the Copilot pane, and any downstream surface that uses this model. Not just a single surface. --- ## When you use this vs. Data Agent instructions - **Semantic Model AI Instructions** — guidance attached to one semantic model. No multi-source routing, no conversational flow. Applies to every Copilot interaction with this model. - **Data Agent** — a separate conversational interface with multi-source routing, few-shot example queries, and conversational response formatting. See the fabric-data-agent skill for data agent specifics. --- ## Setup process Authoring is now available in **both** Power BI Desktop and the Power BI service. Consumption happens everywhere Copilot exists. 1. Open the semantic model in Power BI Desktop, or select the model in the Power BI service. 2. On the **Home** ribbon, click **Prep data for AI**. 3.
