LLM (Large Language Model)

An LLM is an AI model trained on large volumes of text that can understand and generate natural language, serving as the core engine behind AI agents and chatbots.

Common leading LLMs include GPT and Claude. A frequent misconception is assuming the LLM itself already knows a company's internal information — in reality it only holds general knowledge from training, and needs a mechanism like RAG to answer questions about company-specific data.
