Context Window

Technical

What It Means

Context window is like the AI's working memory - it determines how much information the AI can 'remember' and work with in a single conversation or task. Think of it as the size of the AI's desk: a larger context window means it can spread out and reference more documents, chat history, or data at once.

Why Chief AI Officers Care

Context window size directly impacts what business use cases are feasible and affects costs, as larger windows typically cost more to operate. It's a key constraint for enterprise applications like document analysis, customer service chatbots, and complex reasoning tasks that require maintaining context across long interactions.

Real-World Example

A legal AI reviewing a 100-page contract needs a context window large enough to hold the entire document, so it can cross-reference clauses and identify contradictions throughout the whole contract rather than just analyzing it page by page in isolation.

Common Confusion

Many assume AI 'remembers' everything from past conversations, but once the context window fills up, the AI starts 'forgetting' earlier parts of the interaction. The AI doesn't actually have long-term memory between separate sessions.
