Context Window
The amount of text, images, tool results, or other tokens a model can consider in one request.
Plain English
It is the model's short-term workspace.
Example
A long-context model can inspect a whole repository or a large batch of documents before answering.
Why it matters
Large context helps, but long tasks still need retrieval, memory, and summarization discipline.
