In AI, FAQ refers to pre-trained question-answer pairs used by virtual assistants to deliver fast, accurate responses to common queries — without requiring full conversations or complex retrieval workflows for every question.
Rather than routing every question through a reasoning chain, the system matches the input against known questions and returns the associated answer directly. FAQs handle the high-volume, predictable portion of queries so that more capable agents are reserved for genuinely complex requests. It is a simple but effective division of labor that improves response speed and reduces operational cost.
