Description
Large Language Models (LLMs) are transforming how modern applications are built, and this course shows you exactly how to leverage their full power. Whether you are a beginner exploring AI development or a developer looking to integrate LLMs into real-world projects, this course provides a complete, hands-on roadmap.You will start by learning how to interface with LLMs efficiently using LangChain and OpenAI APIs. Step-by-step, you’ll discover how to structure prompts, build chains, and create intelligent workflows that combine models, tools, and outputs. From there, you will explore Retrieval-Augmented Generation (RAG) by building vector stores, generating embeddings, and enabling your applications to access relevant documents and provide more accurate responses.The course also guides you through building multi-retriever agents capable of analyzing queries, pulling data from multiple sources, and performing complex reasoning tasks. You’ll develop interactive chat applications, connect databases such as MongoDB, and implement semantic search pipelines.Finally, you will learn how to deploy your AI applications using Streamlit, LangServe, Replit, and cloud services. By the end of this course, you will have the skills to build, optimize, and deploy powerful AI-driven applications that deliver real value.Whether you’re aiming to enhance your professional skillset or launch new AI projects, this course gives you the practical foundation needed to build the next generation of intelligent applications.
