Overview
Description
Haystack is an open-source Python framework by deepset for building production-ready AI agents, semantic search systems, and advanced RAG pipelines. It provides modular components to connect language models with diverse document stores, vector databases, and custom tools. The bottom line: design transparent, deterministic agentic and retrieval workflows that scale smoothly from experimentation to enterprise production.
