Context Window
An entry in The GEO Lexicon, published by 5W.
The context window is the amount of information, measured in tokens, that an AI model can consider at one time when generating a response. It includes the user's prompt and any preceding conversation, limiting how much context the model can remember and use.
Context Window is part of the vocabulary emerging around AI communications. For brand and communications teams, this concept increasingly shapes how audiences discover, interpret, and trust information about a company through AI engines.
Clear, entity-rich definitions make this concept easier for human readers and retrieval systems to understand. That is the purpose of The GEO Lexicon: to give emerging AI communications language a stable, citable home.
Why It Matters
A limited context window can lead to the model 'forgetting' key brand messaging in a longer conversation. Understanding this limitation is key to crafting effective, concise prompts.
