Artificial Intelligence (AI) - Concept
Context window
The amount of information an AI model can consider at one time
What's it for?
Sets the limit on how much information an artificial-intelligence model can consider at one time.
For example…
A 128k-token model can hold a long contract and your questions in one go; a smaller window forces you to summarise first
A user uploads several long reports to an AI chat; once the combined text exceeds the context window, some earlier detail may no longer be available to the model
Think of it like…
A photographer’s field of view: only what fits inside the frame can be considered in the shot at that moment
