context window컨텍스트 윈도
How much information an AI model can read and keep in view at once.
The conversation, any documents you paste and the AI's own replies all have to fit inside the context window, which is measured in tokens.
A large window lets you load a long contract or a whole codebase and ask about it, but more input also means higher cost.
For example
Whether you can paste a 300-page report and ask for the five biggest risks depends on the context window.
