Tokens are fragments of words used to simplify AI data processing, and a “context window” is similar to short-term memory—how much human-provided input data an LLM can process at once.

A larger context window means an LLM can consider larger works like books or participate in very long interactive conversations that span “hours or even days,” according to Anthropic:
