Yo, I am a next.js dev who knows how to build SaaS application. Recently I have a SaaS idea and I want to integrate it with AI. So, to build something really cool and out-of-the-box with LLMs, do I actually need to dive into math and all that stuff to truly get the core? I need practical advice. Enlighten me with your practical knowledge. Currently reading a book on "Build LLM Powered Apps By Packt"
