Which AI you mean? It's so ubiquitous that it's hard to pick. Categorization and labelling existed before LLM-s, but they made it much better. Imagine not having to manually label support tickets if you have a 1000 new every day.

3D model generation is also a good example, you can save tons of time.

AI is everywhere, but most of the time you simply don't notice it since it's so well integrated or they are driving backend logic, anti fraud systems, etc.
