What is Tokenization?

Tokenization is the process of breaking down text into smaller units called "tokens" that AI models can understand and process. Think of tokens as the basic building blocks of language for AI systems.

Key concepts:

Tokens aren't always words - They can be parts of words, whole words, or even punctuation

Common patterns get their own tokens - Frequent letter combinations like "ing" or "tion" become single tokens

Each color represents a different token - Hover over any token to see its ID number and exact content

Efficiency matters - Better tokenization means AI can process text more efficiently and understand context better
