Context Window
コンテキストウィンドウ(コンテキストウィンドウ)
BeginnerCore Concepts
The maximum amount of text (measured in tokens) that an AI model can process in a single conversation or request.
Why It Matters
A larger context window lets AI handle longer documents, maintain longer conversations, and process more information.
Example in Practice
