What is Context window?
Verified 5 August 2026
Context is finite and priced per token, which makes retrieval a budgeting problem rather than a recall problem. Ten full page bodies can consume a window before the model has decided which page it wanted.
Returning metadata first and full text on request is the direct response: the agent reads titles, snippets and trust signals, decides, and fetches only what it selected.
