# 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](/mosaic/get-started/llm-configuration.md) after activation. Inference cost is billed by your provider, against your account — Mosaic does not handle inference billing.

## Mosaic plan

A Mosaic Standard or Mosaic Premium subscription via Microsoft AppSource.

* **Custom AI agents** require Mosaic Premium
* **Audit log export**, **priority support**, and **quarterly reviews** require Mosaic Premium

## Mosaic plan

A Mosaic Standard or Mosaic Premium subscription via Microsoft AppSource.

* **Custom AI agents** require Mosaic Premium
* **Audit log export**, **priority support**, and **quarterly reviews** require Mosaic Premium

## Recommended

* Familiarity with Power BI Admin Portal tenant settings - you'll touch these during configuration
* A test user account in your tenant for verifying the access flow before rolling out broadly
* A Microsoft Entra security group already created (or permission to create one) for grouping Mosaic users
