What is Large Language Model?

Also known as: LLM

A large language model (LLM) is an AI trained on vast text to predict and generate language, powering chat, reasoning and tool-use in modern AI systems.

LLMs learn statistical patterns of language from enormous datasets, which lets them answer questions, write, summarize, and — when connected to tools — reason about which actions to take.

In an AI OS, the LLM is the reasoning core, but it's not the whole system: it works alongside tools, memory and connectors. The model decides; the mesh acts.
