LLM (Large Language Model)

A large language model is an AI model trained on vast amounts of text to understand and generate human language, the technology behind ChatGPT, Claude, and Gemini.

LLMs increasingly sit between users and websites, answering questions directly instead of sending people to a list of links. Understanding how they retrieve and cite information is the foundation of both GEO and AEO. They generate plausible language, which is why grounding their answers in real sources matters.
