What is an LLM?
A Large Language Model (LLM) is a type of artificial intelligence that’s trained to understand and generate human language. It learns by analysing massive amounts of text, like books, websites, and conversations. It then uses that knowledge to respond in a way that feels natural and human-like.
LLMs are what power tools like ChatGPT and other AI chatbots. They can:
-
Answer questions
-
Write emails, articles, or stories
-
Translate text
-
Summarise information
-
Even hold full conversations
The “large” part refers to the size of the model as it is trained on billions (or even trillions) of words. This scale helps it understand context, tone, and meaning more accurately.
In short, LLMs are the brains behind today’s most advanced language-based AI systems.
