Large Language Model (LLM)
Definition
An AI model trained on huge amounts of text to predict and generate human-like language, powering tools like ChatGPT, Gemini, and Claude.
A large language model (LLM) is a type of AI built to understand and generate text. It is trained on vast collections of writing and learns the statistical patterns of language — effectively learning to predict what word is likely to come next.
LLMs are the engine behind modern chatbots and generative AI text tools. They are powerful at drafting, summarising, and answering questions, but they predict plausible text rather than verified facts, so their output should be checked.
