  Reposition README's opening to highlight 'build from scratch' and 'transparency'

  当前

  Retrieval-Augmented Generation (RAG) pipelines powered by large language models (LLMs) are gaining popularity for building end-to-end question answering systems. Frameworks such as LlamaIndex and Haystack have made significant progress in making RAG pipelines easy to use. While these frameworks provide excellent abstractions for building advanced RAG pipelines, they do so at the cost of transparency. From a user perspective, it's not readily apparent what's going on under the hood, particularly when errors or inconsistencies arise. In this EvaDB application, we'll shed light on the inner workings of advanced RAG pipelines by examining the mechanics, limitations, and costs that often remain opaque.

  This repository demystifies advanced Retrieval-Augmented Generation (RAG) pipelines by building one from scratch, without relying on high-level frameworks like LlamaIndex or Haystack. While those frameworks simplify RAG, they often obscure the underlying mechanics. Here, we provide a transparent, step-by-step guide to understanding, implementing, and troubleshooting advanced RAG systems, revealing the inner workings, limitations, and costs that typically remain opaque.
