It is a composable open-source AI framework designed for building and deploying production-ready applications powered by large language models (LLMs) and multimodal AI. Haystack provides flexible components and pipelines that allow developers to create custom solutions tailored to specific use cases, such as retrieval-augmented generation (RAG), conversational AI, content generation, and agentic workflows. Its modular architecture supports integration with leading LLM providers, vector databases, and AI tools, including OpenAI, Mistral, Weaviate, and Pinecone, offering users the freedom to choose the best technologies for their needs.
Haystack 2.0 is built with production deployment in mind, featuring fully serializable pipelines that are compatible with Kubernetes-native workflows. It includes logging and monitoring integrations for transparency, along with deployment guides for scaling applications across all major cloud platforms and on-premises environments. Developers can extend Haystack’s capabilities using deepset Cloud, which accelerates building, iteration, and deployment processes.
The framework supports multimodal AI tasks, such as image generation, image captioning, and audio transcription, in addition to text-based applications. Its generators provide a standardized chat interface, enabling developers to focus on creating user-friendly bots. Haystack’s prompt flow is highly flexible and composable, leveraging Jinja-2 templates to build content generation engines that align with specific workflows. It also includes a standard function-calling interface for LLMs, allowing them to utilize tools and achieve more complex tasks.
Haystack excels in building highly performant RAG pipelines, offering various retrieval and generation strategies, including hybrid retrieval and self-correction loops. Its pipeline architecture supports branching and looping, making it suitable for advanced agent workflows. The framework is backed by an active community on Discord, where users can engage with others interested in NLP, share knowledge, and stay updated on the latest Haystack news and events. Overall, Haystack is a versatile and production-ready solution for developing next-generation AI applications.
