Definition

The context window defines the operational limit of an AI model’s memory for a single interaction. It determines how much prior conversation history, document text, or input data the model can attend to when generating a response. A larger context window allows for better retention of long-range dependencies and comprehensive document analysis, but it also increases computational costs and latency. Engineers must manage this constraint to optimize performance and ensure relevant information is preserved within the model’s active attention span.
