About Haystack
What is Haystack?
Haystack by deepset is a flexible, open-source framework for developing production-ready NLP applications, including semantic search, question-answering systems, and AI-powered assistants. It supports integration with transformer-based models from Hugging Face, OpenAI, and other providers, enabling retrieval-augmented generation (RAG), document indexing, and natural language understanding. Haystack provides pipelines for search and Q&A, tools for preprocessing and annotating data, and options for real-time or batch processing. Its modular design allows developers to connect various document stores, embeddings, and retrievers to create highly scalable and accurate NLP applications. Haystack is widely adopted in enterprise and research settings for improving knowledge access and AI-driven information retrieval.
