Core Concepts

What is LLM (Large Language Model)?

A type of AI trained on massive text datasets to understand and generate human language.

Definition

A Large Language Model (LLM) is an AI system trained on billions of text documents to predict and generate human-like text. LLMs like GPT-4, Claude, and Gemini use transformer architecture to understand context, follow instructions, and produce coherent responses across a wide range of tasks including writing, coding, analysis, and conversation.

๐Ÿ’ก Example

When you ask ChatGPT to write an email or Claude to analyze a document, you are using an LLM. The model processes your input tokens and generates a response based on patterns learned during training.
