ChatGPT doesn't read words. It reads TOKENS. Here's what that actually means π
Most developers use AI every day β but very few understand what's actually happening under the hood.
Here's what tokens are and why they matter:
πΉ A token is a chunk of text β not always a full word
πΉ "Unbelievable" = 3 tokens: un + believ + able
πΉ LLMs predict the NEXT token, one at a time
πΉ Every model has a token LIMIT (context window)
πΉ You PAY per token when using AI APIs
Understanding tokens will make you:
β
Write better prompts
β
Reduce your API costs
β
Know exactly why AI "forgets" long conversations
This is the foundation of how every LLM works β GPT-4, Claude, Gemini, all of them.
