GLOSSARY
Large Language Model (LLM)
A neural network trained on massive text corpora that predicts and generates language, forming the engine behind every AI chat assistant.
A large language model is a neural network trained on enormous amounts of text — web pages, books, code — to predict the next word so well that it acquires general language ability. Ask it a question and it generates an answer one token at a time, drawing on patterns that span grammar, facts, reasoning styles and even code.
LLMs power the assistants in this directory: ChatGPT, Claude, Gemini and their peers are products wrapped around LLMs, increasingly connected to tools, search and files. Their capability scales with model size, training data and compute — which is why every lab races to train bigger, better ones.
