Is ChatGPT an LLM or generative AI?

ChatGPT is both, and the distinction matters for how we optimise for it. It is a large language model, or LLM, meaning it is trained on vast amounts of text to understand and predict language patterns. It is also a form of generative AI because it creates new responses rather than retrieving fixed answers. At Geo Digital Agency, we work with how these systems actually generate replies. That means shaping the signals, sources, and context ChatGPT draws from, so your brand becomes part of the information it references and confidently presents when users ask questions connected to what you offer.
