Interactive Diagrams
Visual guides to understanding how Claude works. Each diagram explains a core concept that helps you write better prompts and build more effective applications.
Tokenization
How text is broken down into tokens. Each token is a piece of text that Claude processes. Understanding tokenization helps you optimize prompt length and comprehend how Claude counts input.
Context Window
The fixed amount of text Claude can process in a single conversation. Think of it as Claude's working memory. Larger context windows mean you can provide more information, history, and examples.
Tool Use
How Claude can call external functions or APIs. When enabled, Claude can request to use tools like calculators, code execution, or web search to provide better answers.
Agent Loop
The cycle of thought and action. Claude can iteratively think about a problem, take actions (use tools), observe results, and refine its approach. This enables complex problem-solving.
