text: In the example below, 252 characters of human-readable text are shown in tokenized form as 
  57 distinct tokens, the relationships between which then form the basis of building an AI 
  model. The illustration shows a block of human-readable text as it would be tokenized for AI 
  training; different colors are used in this visualization merely to differentiate one token from 
  another within the string of text. As the visualization makes clear, not all of the tokens 
  directly correspond to a single word; tokens merely represent characters that often appear 
  together in the training data. 6
