Overview of this book

The era of generative AI is upon us, and this book serves as a roadmap to harness its full potential. With its help, you’ll learn the core components of the AI stack: large language models (LLMs), vector databases, and Python frameworks, and see how these technologies work together to create intelligent applications. The chapters will help you discover best practices for data preparation, model selection, and fine-tuning, and teach you advanced techniques such as retrieval-augmented generation (RAG) to overcome common challenges, such as hallucinations and data leakage. You’ll get a solid understanding of vector databases, implement effective vector search strategies, refine models for accuracy, and optimize performance to achieve impactful results. You’ll also identify and address AI failures to ensure your applications deliver reliable and valuable results. By evaluating and improving the output of LLMs, you’ll be able to enhance their performance and relevance. By the end of this book, you’ll be well-equipped to build sophisticated AI applications that deliver real-world value.

The need for vector databases

Vectors carry deep semantic information and have many potential use cases that will make them increasingly common over the next few years. Working with them requires specific and complex operations that only process vector data. Additionally, the demand for search can often vary substantially from the demand for more structured database queries.

Together, these factors mean vector operations and traditional database workloads are largely independent. This gives rise to the concept of a vector database that’s designed specifically to handle vector data, indexes, and workloads. From a developer’s perspective, vector databases can take several forms.

The most basic is a standalone product that’s independent from other operational databases. This type of vector database has the freedom to focus solely on implementing and optimizing vector operations without considering other database operations. However, often, vector search applications...
