Also known as: LLM & Large Language Model
Plain English
An AI that understands and writes text.
Definition
A Large Language glossaryModelA model is a system or representation used to process data and generate outputs, often trained to perform specific tasks.Open glossary term is an AI model trained on vast amounts of text glossaryDataData is raw, uninterpreted information collected and stored so it can be analysed, processed, or used to inform decisions. On its own it carries no meaning; context and interpretation are what make it useful.Open glossary term to understand and generate human-like language.
In practice
Used for chatbots, content generation, summarisation, and language-based tasks.
In context
It is best briefed as a capable generalist with no memory and no way of knowing what it does not know. Every design decision around it follows from those two facts.
The reality
LLMs can produce convincing outputs but may be inaccurate or lack real understanding.
