About this course

As artificial intelligence evolves, static language models are no longer enough; modern applications require AI that can actively retrieve custom data and execute multi-step tasks. This course teaches you how to bridge the gap between large language models and your own data sources using LlamaIndex. You will start with the foundational concepts of AI agents and Retrieval-Augmented Generation (RAG), moving step-by-step through the process of building robust, data-backed agentic workflows. What you will learn: Understand the foundational terminology of AI agents, LLMs, and RAG architectures. Configure LlamaIndex to ingest, index, and query your custom data sources. Build basic RAG pipelines to improve the accuracy and relevance of AI responses. Design agentic workflows that can break down complex queries and route tasks effectively. Integrate modern vector databases to store and retrieve data efficiently. Apply prompt engineering basics to guide your agents toward reliable outputs. The course begins with essential terminology and fundamental concepts before guiding you through written exercises to construct your first data indices and agentic loops. You will progress from simple document queries to designing multi-step AI agents capable of reasoning over complex datasets. This course is designed for beginners, aspiring data engineers, and developers with no prior AI experience who want to understand the mechanics of agentic workflows. Start reading today to unlock the potential of your data and build your first intelligent AI agent.

Eu já tinha brincado com RAG por conta própria, mas sempre de forma confusa, e este curso finalmente organizou tudo na minha cabeça. A forma como o LlamaIndex é usado para indexar e recuperar documentos ficou muito clara, e entendi de verdade como conectar os dados ao agente. Gostei especialmente da parte sobre estruturar o índice para respostas mais precisas. Montei um agente que responde com base na minha própria documentação e funcionou lindamente. As explicações são diretas e os exemplos práticos do início ao fim. É o melhor material que encontrei sobre agentes apoiados em dados.

사내 문서를 기반으로 답하는 챗봇을 만들고 싶었는데, 이 강의 덕분에 LlamaIndex로 데이터를 인덱싱하고 검색하는 과정을 제대로 이해했어요. RAG가 막연한 유행어처럼 느껴졌었는데, 문서를 어떻게 쪼개고 어떻게 불러와야 정확한 답이 나오는지 단계별로 짚어주니 머릿속이 정리됐습니다. 예제 코드도 그대로 돌아가서 제 자료로 바꿔 바로 적용할 수 있었고요. 특히 검색 품질을 높이는 부분 설명이 실무에 큰 도움이 됐습니다. 데이터 기반 에이전트를 만들고 싶은 분께 자신 있게 추천합니다.
