About Tokenization

What is Tokenization?

Tokenization is the process of breaking text into smaller units (called tokens). Large language models use these tokens to understand and generate text. Different models use different tokenization algorithms, which affects their performance and efficiency.

Why is Tokenization Important?

Understanding how models break text into tokens is crucial for optimizing prompts, reducing token usage, and lowering API costs. By visualizing the tokenization process, developers can better understand how models work and create more effective applications.
