Awesome. Welcome everyone to the final day of the boot camp. Uh, today we're gonna be talking about literally every single buzzword in the AI space right now. We're gonna be talking about vector databases, rag and fine tuning. Uh, it's gonna be a lot. Uh, at the end of this, uh, lecture in the lab today, we're gonna be building Zac GPT, which is a rag-based system on top of GPT 4. That gives you essentially Zach flavored GPT 4. it's gonna be pretty awesome. I'm really excited for today's lecture. Uh, I hope this gives y'all some insight into how a lot of these AI systems are generated and how you can use these things and learn more about these things to uh build into the, this new AI world. OK, but first, uh, we have 3 people that we need to uh congratulate here. We have, uh, Jesse, uh, he was the most active, um, participant in the Discord for the entire boot camp. So congratulations, Jesse, uh, you get your money back. Uh, so you get all of, you get to do this entire boot camp for free. Uh, same with Nikil. Uh, Nikil, uh, he had the best jokes in the entire boot camp, by far, by the way, like the funniest man by far. And so, uh, I easily, another refund, just, uh, he gets to do the boot camp for free. And then Sudeep, I, I tried to find Sudeep's like LinkedIn. And like, uh, me and Matali debated on whether or not it was the right Sundeep.
