Glossary
LLM (large language model)
An AI model trained on huge amounts of text to predict and generate language. It’s the “engine” behind chatbots such as ChatGPT, Gemini or Claude.
Common mistake
Thinking it “knows” or “looks things up” like a person. It predicts likely text; without search enabled, it consults nothing.
