Alright y'all. All right, y'all. Welcome to the 2nd day of LLM driven data engineering. Uh, we're gonna be talking about a little bit more of the, uh, kind of state of the art kind of stuff in some regards. And, um, hopefully y'all caught up on the, the first lecture. Um, it's in the GitHub repo if you have not. And so, yeah, this is gonna be great. I'm, I'm really excited to be doing this presentation with y'all. and yeah, let's, uh, let's get into it. OK, so what are we talking about today? So, we talk about 3 things for the most part. One is like, how should we build apps with LLMs, and then we're gonna be talking about Lang chain. I'm sure y'all have seen Lang chain. Langchain is pretty cool. And then we're gonna talk about uh privacy and security, because I've always found that to be an interesting kind of topic when you're ever you're building out these apps. And yeah, this is gonna be pretty awesome. And then uh we're gonna have a lab uh later uh after this presentation, that will be also really awesome. And so, yeah, uh, let's, uh, let's get into these topics. They're gonna be a good one. OK.
