What is Large language model (LLM)?

A large language model is an AI system trained on huge amounts of text to predict and generate language. GPT-6.1, Claude 5.5, Muse and Grok are all LLMs. They don't look things up like a search engine — they generate answers from patterns learned in training, plus whatever context you give them.
