Core Concepts
Large Language Model (LLM)
The AI model that powers intelligent, context-aware chatbot responses.
A large language model (LLM) is a neural network trained on vast amounts of text data, giving it the ability to understand, generate, and reason about natural language. LLMs like GPT-4, Claude, and Gemini are the engines behind modern AI chat agents. When you deploy an AI chatbot on your website, an LLM processes each visitor message and generates an appropriate response. The quality, tone, and accuracy of those responses depends heavily on which LLM is used and how the system prompt is configured.
