In plain language

An LLM is a large AI model built to work with language. This describes what the model or system does, not a promise that every product behaves identically.

An analogy

Picture a language engine trained on vast amounts of text—not a person who has understood the whole internet.

The analogy is a shortcut, not a complete technical definition.

An everyday example

Where you will encounter it

The term appears around chatbots, writing tools, coding assistants and AI search.

Should you care?

Most users only need to know that it powers many language features.

How it differs

An LLM is a model, not the whole product. Large size also does not guarantee that every answer is correct.
