“Haystack is deepset’s open-source AI orchestration framework for building production-ready AI agents, advanced RAG systems, multimodal applications, search, question answering, and other LLM-powered systems. It lets developers structure AI applications as explicit, modular pipelines made of retrievers, routers, memory layers, tools, evaluators, and generators, so each component can be tested, replaced, and improved independently, with full model and data flexibility.”
