What it is

A Large Language Model is the technology engine behind AI tools like ChatGPT, Claude, and Gemini. It's a type of software trained on enormous amounts of text — books, websites, articles — that learned to predict and generate language that sounds coherent and human. It doesn't think. It pattern-matches at a massive scale.

Why it matters

LLMs are what decide whether your business gets mentioned when someone asks an AI for a recommendation. Understanding that they work from patterns — not real-time searches — explains why what you've published online, and how trustworthy it looks, determines whether you get cited or ignored.

The mistake most people make

Thinking LLMs are all-knowing and always current. They're trained on data up to a cutoff point, which means they may not know about your recent rebranding, new service, or updated pricing. Your content strategy needs to account for this lag.
