+## Why do we need vectors?
 
 Computers can't understand text. They can only understand numbers. So, we need a way to convert text into numbers. That's where vectors come in.
 
-Using vectors, we can plot text in a multi-dimensional space. It is hard to visualize a multi-dimensional space, so let's start with a 2-dimensional space.

-The big breakthrough with GenAI is that developers can now easily use models that have been pre-trained, and made available freely online. These models have been trained on huge datasets, and are able to convert text (or any sort of data, really) into vectors.

-There are many ways to create vectors. In this workshop, we'll use a pre-trained model and an API that will return vectors for us.
