Summary

This chapter explored the transformative impact of index-based search on RAG and introduced a pivotal advancement: full traceability. The documents become nodes that contain chunks of data, with the source of a query leading us all the way back to the original data. Indexes also increase the speed of retrievals, which is critical as the volume of datasets increases. Another pivotal advance is the integration of technologies such as LlamaIndex, Deep Lake, and OpenAI, which are emerging in another era of AI. The most advanced AI models, such as OpenAI GPT-4o, Hugging Face, and Cohere, are becoming seamless components in a RAG-driven generative AI pipeline, like GPUs in a computer.

We started by detailing the architecture of an index-based RAG generative AI pipeline, illustrating how these sophisticated technologies can be seamlessly integrated to boost the creation of advanced indexing and retrieval systems. The complexity of AI implementation is changing the way we organize...
