“AI” is a marketing label wrapped around a stack of much more specific things: models, data, training procedures, and the infrastructure that lets all of it run cheaply enough to matter.
When someone says “we added AI”, what they usually mean is one of:
- We are calling a hosted language model from a vendor.
- We trained or fine-tuned a model on our own data.
- We bolted a retrieval system onto a pre-trained model.
The differences matter — for cost, for privacy, and for what actually ships.
