description Overview

Haystack (Deepset)

Haystack is a mature, end-to-end framework focused heavily on building robust Retrieval-Augmented Generation (RAG) pipelines. It provides excellent tools for document ingestion, chunking, embedding, and sophisticated retrieval strategies. While perhaps less focused on the 'agent' aspect than others, its unparalleled depth in making the *retrieval* step reliable makes it a powerhouse for knowledge-...
