Haystack
Haystack is an orchestration framework designed for building complex search and generative AI pipelines. It functions as an agentic workflow engine, enabling the construction of automated sequences that allow AI agents to perform multi-step reasoning and data analysis.
The framework utilizes a modular, component-based architecture that connects processing steps into directed acyclic graphs. By employing a provider-agnostic integration layer, it decouples core logic from specific external AI services and vector databases, allowing for the flexible exchange of underlying technologies. This design supports the development of custom retrieval systems that provide context-aware answers from large datasets.
Beyond text-based retrieval, the platform includes tools for multimodal data processing and indexing. It normalizes diverse media formats, including images and audio, into a unified representation to ensure consistent analysis across different types of content. The system also incorporates observability hooks to monitor state changes during the execution of complex workflows.
