Token

A unit of text or code in natural language processing and machine learning models.

Description

In the context of natural language processing and machine learning, a token is a basic unit of text or code. Tokenization is the process of breaking down text into these smaller units, which can be words, subwords, or even characters, depending on the specific implementation. Tokens are crucial for language models as they form the basis of how these models process and generate text. The number of tokens in a piece of text often determines the computational resources required to process it.
