# Large Language Model (LLM)

A large language model (LLM) is an AI trained on vast amounts of text to understand and generate human language, the engine behind tools like ChatGPT and Claude.

## Definition

An LLM predicts the most likely next words given everything before them, which lets it summarise, draft, classify, translate and reason over language. On its own it’s a capable generalist; the business value comes from connecting it to your data and tools.
