A Large Language Model (LLM) is the AI 'brain' that decides what an AI voice agent should say next based on the conversation. Examples include GPT-4, Claude, Gemini, and Llama. The LLM processes the conversation history, the system prompt (instructions), and the caller's latest message to generate an appropriate response.
