Context window
컨텍스트 창
The amount of text an AI can see and remember at one time.
Overview
Your conversation with the AI, any documents you paste in, and your instructions all go inside the context window. Its size is set in tokens. If you go over it, the AI forgets the earliest content or cannot accept more.
With a bigger window, the AI can read and answer about a whole long report or a large program. But a big window does not mean the AI remembers everything in it equally well.
An everyday example
It is like the size of your desk. A wide desk lets you spread out many papers, but extra papers have to go on the floor.
Why it matters
Whether the AI can summarize a long document, hold a long conversation or work on a large codebase depends on this. It is also why the AI forgets earlier agreements as a conversation gets longer.
