Context window
Definition The maximum amount of text, measured in tokens, an AI model can consider at one time—covering the instructions, any documents provided, and the response. Material beyond the window is invisible to the model.
In more depth
The context window functions as the model's working memory for a single exchange. Modern models accept very large windows—enough for entire contracts or briefs—but accuracy in recalling details can degrade as input grows, and anything outside the window is simply not seen. When a long conversation exceeds the window, earlier content may be dropped or summarized, which can cause the model to lose track of instructions or facts stated earlier.
