Haystack

Haystack is an open-source Python orchestration framework designed for building production-ready RAG pipelines and agentic workflows through a modular, component-based architecture. It utilizes Directed Acyclic Graphs (DAGs) to manage data flow between document stores, retrievers, and LLMs, offering a trade-off between high-level abstraction for rapid development and granular control over pipeline execution paths.

Disambiguation

An orchestration framework by deepset, distinct from the 'Needle-in-a-Haystack' performance evaluation benchmark.

Visual Metaphor

"An industrial assembly line where modular stations (retrievers, rankers, generators) are connected by configurable conveyor belts to transform raw data into an answer."
