What Is Generative AI?

Generative AI is software that creates new content — text, images, code, audio — instead of just sorting or labelling existing content.

Old software mostly recognised things: "is this email spam, yes or no?" Generative AI produces things: "write me a reply to this email."

The most common kind you'll meet is the Large Language Model (LLM) — the engine behind ChatGPT, Claude, and Gemini. For the rest of this track, "the model" means an LLM.
