Models

Models are a fundamental unit in Wren AI that combines schemas, metadata, relationships, calculated fields, and more custom semantic information from the tables of your data source. They help both people and Wren AI service better understand data.

Create a model​

Create a model from the connection process​

During the connection process, you are asked to select which tables you want to use in Wren AI.

These selected tables will automatically be created as data models.

tip

Wren AI allows connecting only the necessary tables from your sources. If you change your mind about which tables to connect and columns to sync, you can modify this in the project settings.
