Context Window
The amount of text an AI can keep in mind at once — its short-term working memory for a single task.
The context window is how much information an AI can hold and consider at one time — the current conversation, the documents you've given it, and its own draft. Think of it as the model's desk space: everything it's actively using has to fit on the desk at once.
When a task runs past that limit, the AI can start to forget earlier details or need the material trimmed down. Bigger context windows let an AI work with longer documents and richer background in a single pass — useful when you want it to reason over a whole report or a long email thread rather than a snippet.
Why it matters
It shapes how much of your business an AI can weigh in one go — and why feeding it the right, focused information gets better results.
