I suppose I'm just a little bit bothered by your saying you "built an AI" when all the heavy lifting is done by a pretrained LLM. Saying you made an AI-based program or hell, even saying you made an AI agent, would be more genuine than saying you "built an AI" which is such an all-encompassing thing that I don't even know what it means. At the very least it should imply use of some sort of training via gradient descent though.

It is an application of AI which is just software, and applying it to solve a problem or need.
