Open-source framework for building AI search pipelines and question-answering systems.

Description

Haystack is an end-to-end open-source framework by deepset for building AI-powered search and question-answering applications. Specialized in neural search, RAG systems, and NLP pipelines, it enables the creation of agents that can search through documents, answer complex questions, and extract specific information. It offers modular components for document stores, retrievers, readers, and generators. Haystack supports hybrid search, combining keyword-based and semantic search. It includes integrations with popular vector databases such as Elasticsearch, Weaviate, Pinecone, and more. Compatible with Hugging Face transformers and OpenAI LLMs, it also allows for model fine-tuning for specific use cases. Ideal for building intelligent search engines, Q&A systems over documentation, and research assistants. Open source with an active community, it is used in production by companies for enterprise search and knowledge automation.
