Prerequisites
Before installing Mosaic, confirm your organisation has the following.
Mosaic is bring-your-own-licence (BYOL) for both Power BI and AI inference. The Mosaic subscription covers the platform — workspaces, collaboration, agents, audit, integration. Power BI capacity and LLM inference are on you, in your own tenant. This keeps your data in your environment and your spend visible to your finance team.
Microsoft 365 tenant
Mosaic uses Microsoft Entra ID as its sole identity provider. You need:
An active Microsoft 365 tenant
A Microsoft Entra administrator who can grant tenant-wide admin consent when Mosaic is installed for the first time
Power BI capacity in your tenant
Mosaic plugs into the Power BI you already have. Embedded reports must be backed by your own capacity. One of the following is required:
Microsoft Fabric capacity (F-SKU)
Power BI Premium
Power BI Premium Per User (PPU) for every user who will sign in to Mosaic
Power BI Embedded capacity (A-SKU)
Mosaic does not include or resell Microsoft licensing. The capacity sits in your Microsoft 365 tenant, not Vizlake's.
Power BI workspace and content
At least one Power BI workspace assigned to a capacity above
The reports, dashboards, and datasets you intend to embed must already live in that workspace
You must have admin or member access on those Power BI workspaces
LLM capacity in your tenant
Mosaic does not bundle AI inference. You bring your own LLM capacity, and Mosaic routes every chat, agent run, and DAX-generation call through it. One of the following is required:
Azure AI Foundry project (recommended) — a deployed model in your own Azure subscription. Cleanest data-residency and billing story for Microsoft-native customers.
Anthropic API key — direct integration with the Claude family
OpenAI API key — direct integration with GPT-4 / GPT-4o
You'll connect this in LLM Configuration after activation. Inference cost is billed by your provider, against your account — Mosaic does not handle inference billing.
