Generative AI Architectures with LLM, Prompt, RAG, Vector DB (Udemy.com)

In this course, you'll learn how to Design Generative AI Architectures with integrating AI-Powered S/LLMs into EShop Support Enterprise Applications using Prompt Engineering, RAG, Fine-tuning and Vector DBs.

We will design Generative AI Architectures with below components;

1. Small and Large Language Models (S/LLMs)

2. Prompt Engineering

3. Retrieval Augmented Generation (RAG)

4. Fine-Tuning

5. Vector Databases

We start with the basics and progressively dive deeper into each topic. We'll also follow LLM Augmentation Flow is a powerful framework that augments LLM results following the Prompt Engineering, RAG and Fine-Tuning.

Large Language Models (LLMs) module;
