What is Large Language Model (LLM)?

An AI system trained on vast text data to understand and generate human-like text.

By Council Research TeamUpdated: Jan 27, 2026

Definition

A Large Language Model (LLM) is a type of artificial intelligence trained on massive datasets of text to understand context, answer questions, write content, and perform various language tasks. Models like GPT-4, Claude, and Gemini are examples of LLMs. They use transformer architecture and can contain billions of parameters.

Examples

1ChatGPT (GPT-4)
2Claude (Anthropic)
3Gemini (Google)
4LLaMA (Meta)

Why It Matters

LLMs power most modern AI assistants. Understanding how they work helps you use them more effectively.

Related Terms

Transformer (Architecture)

The neural network architecture behind modern AI like GPT and Claude.

Token (AI)

A chunk of text (roughly 4 characters or 3/4 of a word) that AI models process.

Fine-Tuning

Training an AI model on specific data to specialize it for particular tasks.

Prompt Engineering

The practice of crafting effective instructions to get better results from AI models.
