Token
Also known as: tokens
In one line
The unit of text an AI reads and generates — roughly ¾ of a word.
What does Token mean?
LLMs process text in tokens, not letters or words. 1,000 tokens ≈ 750 English words. Pricing and context windows are measured in tokens.
A real-world example
The word "SynaBot" is 3 tokens; "hello world" is 2 tokens.
