LLM · large language model
An LLM (Large Language Model) is a model trained on huge volumes of text to understand and generate language. It is the engine behind ChatGPT, Gemini or Claude.
Why it matters
Understanding what an LLM is helps you know what it can do (reason over text) and its limits: it predicts plausible text, it does not truly know. That is the basis for picking the right model and avoiding misuse.
