Also called: vectors, vector representation, list of numbers

An ordered list of numbers. In AI, a vector stands for a piece of text, an image or a sound, with each number capturing one aspect of it. An [embedding](https://ecosystem.samcarlton.com/embedding) is a vector.

**For example:** The word 'coffee' might be stored as a vector of 768 numbers that starts 0.12, -0.48, 0.91.
