Large Language Model (LLM)

An AI model trained on huge amounts of text to predict and generate language. LLMs power chatbots like ChatGPT and Claude.

Why it matters

LLMs are the engines behind most of the AI tools people use today, so understanding them explains why these tools are fluent but also why they sometimes get facts wrong.

Example

ChatGPT, Claude, and Gemini are all built on large language models.
