LLMs are huge pretrained models. The economic benefit here is that you don't have to train your own text classification model anymore. (The LLM was likely already trained on whatever training set you could think of.)

That's a big time and effort saver, but no different from "AI" that we had decades prior. It's just more accessible to the normal person now.
