From the glossary
Every entry has a plain-English definition and an example from a real job. Here are three of the 110 terms.
The amount of text, measured in Tokens, that a Model can consider at once. It includes your instructions, attached files, the conversation so far and the answer being written. When a conversation grows past it, earlier material drops out or must be summarized.
At work: A manager pastes a 300-page policy manual into a chat and gets an error; the manual is larger than the tool's Context Window.
An AI answer that sounds confident and plausible but is false, such as an invented statistic or a citation to a report that does not exist. Also called confabulation.
At work: A paralegal checks every case the AI Chatbot cites and finds that one of them does not exist.
An AI system that works toward a goal by deciding its own next steps and using tools, such as searching, reading files or updating records, instead of only replying with text.
At work: An agent receives a vendor's change request, looks up the contract, drafts a reply and creates a task for the buyer to approve.
