Haystack
An open-source framework from deepset for building search, RAG, and agent pipelines.
Definition
Haystack is an open-source LLM orchestration framework from deepset for building production natural-language systems like question answering, semantic search, and retrieval-augmented generation. It models a workflow as a pipeline of components — retrievers, rankers, readers, generators — that can be swapped and connected, and it integrates with many vector stores and model providers. It is used to assemble retrieval and agent applications.
