[Update Course] Generative AI Architectures with LLM, Prompt, RAG, Vector DB | Udemy

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;

• How Large Language Models (LLMs) works?
• Capabilities of LLMs: Text Generation, Summarization, Q&A, Classification, Sentiment Analysis, Embedding Semantic Search, Code Generation
• Generate Text with ChatGPT: Understand Capabilities and Limitations of LLMs (Hands-on)
• Function Calling and Structured Output in Large Language Models (LLMs)
• LLM Models: OpenAI ChatGPT, Meta Llama, Anthropic Claude, Google Gemini, Mistral Mixral, xAI Grok
• SLM Models: OpenAI ChatGPT 4o mini, Meta Llama 3.2 mini, Google Gemma, Microsoft Phi 3.5
• Interacting Different LLMs with Chat UI: ChatGPT, LLama, Mixtral, Phi3

• Modernizing and Design EShop Support Enterprise Apps with AI-Powered LLM Capabilities
• Develop .NET to integrate LLM models and performs Classification, Summarization, Data extraction, Anomaly detection, Translation and Sentiment Analysis use cases.

Prompt Engineering module;

• Steps of Designing Effective Prompts: Iterate, Evaluate and Templatize
• Advanced Prompting Techniques: Zero-shot, One-shot, Few-shot, Chain-of-Thought, Instruction and Role-based
• Design Advanced Prompts for EShop Support – Classification, Sentiment Analysis, Summarization, Q&A Chat, and Response Text Generation

Retrieval-Augmented Generation (RAG) module;

• The RAG Architecture Part 1: Ingestion with Embeddings and Vector Search
• The RAG Architecture Part 2: Retrieval with Reranking and Context Query Prompts
• The RAG Architecture Part 3: Generation with Generator and Output
• E2E Workflow of a Retrieval-Augmented Generation (RAG) – The RAG Workflow
• Design EShop Customer Support using RAG
• End-to-End RAG Example for EShop Customer Support using OpenAI Playground
• Develop RAG – Retrieval-Augmented Generation with .NET, implement the full RAG flow with real examples using .NET

Fine-Tuning module;

• Fine-Tuning Workflow
• Fine-Tuning Methods: Full, Parameter-Efficient Fine-Tuning (PEFT), LoRA, Transfer
• Design EShop Customer Support Using Fine-Tuning
• End-to-End Fine-Tuning a LLM for EShop Customer Support using OpenAI Playground

Also, we will discuss

• Choosing the Right Optimization – Prompt Engineering, RAG, and Fine-Tuning

Vector Database and Semantic Search with RAG module

• What are Vectors, Vector Embeddings and Vector Database?
• Explore Vector Embedding Models: OpenAI – text-embedding-3-small, Ollama – all-minilm
• Semantic Meaning and Similarity Search: Cosine Similarity, Euclidean Distance
• How Vector Databases Work: Vector Creation, Indexing, Search
• Vector Search Algorithms: kNN, ANN, and Disk-ANN
• Explore Vector Databases: Pinecone, Chroma, Weaviate, Qdrant, Milvus, PgVector, Redis

Lastly, we will Design EShopSupport Architecture with LLMs and Vector Databases

• Using LLMs and VectorDBs as Cloud-Native Backing Services in Microservices Architecture
• Design EShop Support with LLMs, Vector Databases and Semantic Search
• Azure Cloud AI Services: Azure OpenAI, Azure AI Search
• Design EShop Support with Azure Cloud AI Services: Azure OpenAI, Azure AI Search

This course is more than just learning Generative AI, it’s a deep dive into the world of how to design Advanced AI solutions by integrating LLM architectures into Enterprise applications.

You’ll get hands-on experience designing a complete EShop application, including LLM capabilities like Summarization, Q&A, Classification, Sentiment Analysis, Embedding Semantic Search, Code Generation.
