In coding and AI, a token is often a string of characters that represents a specific value or element. For example, in programming, a token can be a keyword, operator, or identifier used in code.
In the context of AI, tokens are used to process language. For instance, in a sentence, each word or punctuation mark can be considered a token. This helps AI understand and generate text more effectively.
Tokens are crucial for tasks like natural language processing, where breaking down text into manageable pieces allows for better analysis and understanding.
Example
In the sentence 'Hello, world!', there are three tokens: 'Hello', ',', and 'world'.
