LlamaIndex Tutorials

About this course

LlamaIndex is the industry standard framework for building Retrieval-Augmented Generation (RAG) applications — the technology powering intelligent AI systems that can reason over your own data. These official tutorials from the LlamaIndex team guide you through building production-grade AI applications, from indexing documents to deploying sophisticated agents that handle real-world tasks.

Whether you're building customer support bots, research assistants, or data-driven AI products, LlamaIndex gives you the tools to move beyond generic ChatGPT and create AI systems that work with your actual information.

What you'll learn

• Build a complete RAG pipeline: index documents, create retrieval systems, and query your data with semantic understanding
• Design and deploy intelligent agents that break down complex tasks, make decisions, and take action autonomously
• Evaluate RAG system quality using benchmarks and metrics — move beyond guesswork to measurable improvements
• Optimize retrieval and generation: chunk documents smartly, choose the right embedding models, and tune prompts for accuracy
• Connect LlamaIndex to production environments: API integrations, caching, and scaling patterns for real applications
• Debug and iterate: understand failure modes in RAG systems and apply practical fixes
• Implement advanced patterns: multi-document reasoning, structured outputs, and context-aware response generation

Who this is for

You're an intermediate developer or AI enthusiast ready to move beyond tutorials and build systems that actually work with real data. If you've played with ChatGPT but want to understand the engineering behind intelligent applications, this course teaches you that craft.

• AI/ML engineers and researchers — deepen your RAG expertise and master the framework used across dozens of production AI startups in India and globally
• Full-stack and backend developers — learn how to integrate AI into your applications without becoming a researcher; get practical, code-first knowledge
• Product managers and technical founders — understand what's possible with RAG and agents, and how to evaluate AI tool options for your product

Prerequisites

Solid Python knowledge is essential — you should be comfortable with functions, APIs, and libraries. Basic familiarity with how large language models work (embeddings, tokens, prompts) will help, but isn't required. You don't need prior RAG experience; the course builds from fundamentals.

Why this matters for Indian learners

RAG and agentic AI are reshaping how Indian tech companies compete globally. Startups in Bangalore, Mumbai, and Delhi are actively hiring engineers who can build RAG systems for use cases like customer service automation, financial advisory chatbots, and research tools — roles that command 25–40% premiums over standard backend developer salaries.

Learning LlamaIndex directly from official documentation also means you're learning from the same source that engineers at companies like Perplexity, Weaviate, and enterprises using LlamaIndex in India use. This skill transfer is immediate and credible.

Frequently asked questions

Is this course really free?

Yes, completely free. You're accessing LlamaIndex's official documentation and tutorials with no paywalls or hidden costs.

How long will it take to complete?

The course is structured as 8 hours of focused material. We recommend 1–2 hours per week alongside hands-on coding practice — so plan 4–8 weeks if you're applying concepts as you learn. If you're reviewing quickly, you can move faster.

Will I get a certificate?

This course doesn't issue a formal certificate. However, the best proof of completion is building a project with LlamaIndex and sharing it on GitHub — that carries far more weight in the job market than a certificate anyway.
