Large Language Model (LLM)

Models and Architectures

An AI model trained on enormous amounts of text to understand and generate human language. ChatGPT, Claude, and Gemini are built on LLMs.

A large language model learns language by reading a giant portion of the internet, books, and other text. Its core skill is deceptively simple: predicting the next word. Done at massive scale, that skill produces fluent answers, summaries, translations, and code.LLMs do not look facts up in a database - they generate text from learned patterns. That makes them flexible and articulate, but also capable of confidently stating things that are wrong, so their answers should be checked for anything important.
