Definition
A large language model (LLM) is an AI system trained on vast amounts of text that can understand and generate human language. In voice AI, the LLM interprets what a caller says and decides how the agent should respond.
Why it matters
The LLM is the reasoning brain of a voice agent; choosing and configuring it well drives conversation quality and accuracy.
