Context Window

Noun · AI & Machine Learning

Definitions

  1. The maximum number of tokens (input + output) that a language model can process in a single interaction. Determines how much text the model can 'see' at once. Larger context windows enable processing entire codebases or documents but increase compute cost quadratically.

    In plain English: The maximum amount of text an AI can read and consider at once — like the size of its working memory.

    Example: "Claude's 200K context window means you can paste an entire codebase and ask it to find bugs across files."
