AI Reads Tiny Word Chunks Called Tokens
AI does not read full words. It reads little chunks called tokens.
Explorers · AI Foundations · ~4 min read
The big idea
AI breaks every message into small chunks called tokens before reading. A token is often a piece of a word.
Some examples
- The word 'unhappy' might be 2 tokens: 'un' + 'happy'.
- A short word like 'cat' is usually 1 token.
- Spaces and punctuation can be tokens too.
- 100 words is roughly 130 tokens in English.
Try it!
Type 'pineapple' to AI and ask how many tokens that is. Most AIs split it into 2 or 3 chunks.
Practice this safely
Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about token, not to let it make the decision for you.
- 1Ask AI to explain token in plain language, then underline anything that sounds uncertain or too broad.
- 2Give it one detail from "AI Reads Tiny Word Chunks Called Tokens" and ask for two possible next steps plus one reason each step might be wrong.
- 3Check AI input against a trusted source, teacher, adult, expert, or original document before you use it.
