LLM (Large Language Model)

An LLM (Large Language Model) is a type of AI system trained on vast amounts of text to understand and generate human-like language. Examples include GPT-4, Claude, and Llama. LLMs power many marketing automation tools, from content generation to data analysis. They work by predicting the next word in a sequence based on context, enabling tasks like summarization, translation, and question answering. While powerful, LLMs can hallucinate facts or produce generic content—human review and grounding in real data are essential for reliable outputs.
