Large language model (LLM)
A large language model, or LLM, is a model trained on large collections of text and related data to predict and generate language. It can draft, summarize, classify, translate, or reason over context, but it does not automatically know what is true for your company.

LLMs are often the visible AI layer, so teams need simple language for their limits, costs, and review needs.
