Understanding Token Usage

What is a token?

Tokens are the basic units that AI models process. They're not exactly words—they're pieces of words, sometimes characters, sometimes larger chunks. Different languages tokenize differently. English typically averages about 0.75 words per token, but this varies widely.

Why tokens matter

Understanding token usage helps you optimize your AI interactions: stay within context limits, reduce costs, and improve performance. For large-scale applications, efficient token use can significantly impact your budget and system responsiveness.

Optimizing token usage

To reduce token usage: be concise, use structured formats when possible, choose lower detail levels for images when appropriate, and consider chunking large documents strategically. For API interactions, monitor and analyze your token usage patterns to identify optimization opportunities.
