• 2024-05: fastRAG V3 is Haystack 2.0 compatible 🔥
• 2023-12: Gaudi2 and ONNX runtime support; Optimized Embedding models; Multi-modality and Chat demos; REPLUG text generation.
• 2023-06: ColBERT index modification: adding/removing documents; see IndexUpdater.
• 2023-05: RAG with LLM and dynamic prompt synthesis example.
• 2023-04: Qdrant DocumentStore support.

• Optimized RAG: Build RAG pipelines with SOTA efficient components for greater compute efficiency.
• Optimized for Intel Hardware: Leverage Intel extensions for PyTorch (IPEX), 🤗 Optimum Intel and 🤗 Optimum-Habana for running as optimal as possible on Intel® Xeon® Processors and Intel® Gaudi® AI accelerators.
• Customizable: fastRAG is built using Haystack and HuggingFace. All of fastRAG's components are 100% Haystack compatible.

For a brief overview of the various unique components in fastRAG refer to the Components Overview page.

Preliminary requirements:

• Python 3.8 or higher.
• PyTorch 2.0 or higher.

To set up the software, install from pip or clone the project for the bleeding-edge updates. Run the following, preferably in a newly created virtual environment:

pip install fastrag

There are additional dependencies that you can install based on your specific usage of fastRAG:

# Additional engines/components
pip install fastrag[intel]               # Intel optimized backend [Optimum-intel, IPEX]
pip install fastrag[openvino]            # Intel optimized backend using OpenVINO
pip install fastrag[elastic]             # Support for ElasticSearch store
pip install fastrag[qdrant]              # Support for Qdrant store
pip install fastrag[colbert]             # Support for ColBERT PLAID; requires FAISS
pip install fastrag[faiss-cpu]           # CPU-based Faiss library
pip install fastrag[faiss-gpu]           # GPU-based Faiss library

To work with the latest version of fastRAG, you can install it using the following command:

pip install .

pip install .[dev]
