Context Window
How much text a model can hold in mind at once, counted in tokens. Anything beyond it is forgotten, which is why very long conversations start to lose earlier details.

Agentic Browsing
An AI navigating a website on somebody’s behalf: finding the price, checking availability, sometimes buying. Sites that rely on hover menus and unlabelled buttons are hard for an agent to use.
Content Freshness
How recently a page was published or genuinely updated. It matters most for things that change — prices, availability, guidance — and matters little for things that do not.
OAI-SearchBot
The crawler OpenAI uses to answer live searches in ChatGPT, separate from GPTBot. Blocking one does not block the other, so a site can be absent from ChatGPT search while still being read for training.
Neural Network
A system of simple connected units, loosely inspired by the brain, that learns patterns from examples rather than following rules somebody wrote. Nearly all modern AI is built on one.
Grounding
Giving an AI real source material to answer from, instead of letting it rely on memory. A grounded answer can be checked and cited; an ungrounded one is where hallucinations come from.
Vector Database
A database built to store embeddings and find the closest matches quickly. It is the part of an AI search system that decides which of your pages is relevant to a question.
