LlamaIndex: The Hidden Jewel - An Introduction to the LlamaIndex Ecosystem

Now that you’ve got a solid understanding of what large language models (LLMs) are and what they can (and cannot) do. It’s time to discover how LlamaIndex can take your interactive AI applications to the next level. We’ll explore how retrieval-augmented generation (RAG) using LlamaIndex can provide the missing link between the vast knowledge of LLMs and your proprietary data.

In this chapter, we will cover the following main topics:

• Optimizing language models – The symbiosis of fine-tuning, RAG, and LlamaIndex
• Discovering the advantages of progressively disclosing complexity
• Introducing personalized intelligent tutoring system (PITS) – our hands-on LlamaIndex project
• Preparing our coding environment
• Familiarizing ourselves with the structure of the LlamaIndex code repository
