Key Features
- 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.

:round_pushpin: Installation
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:
via pip pypi:
pip install fastragor from a local clone:
pip install .There are several dependencies to consider, depending on your specific usage (also works with pip install fastrag[*] package):
# Additional engines/components
pip install .[intel] # Intel optimized backend [Optimum-intel, IPEX]
pip install .[elastic] # Support for ElasticSearch store
pip install .[qdrant] # Support for Qdrant store
pip install .[colbert] # Support for ColBERT+PLAID; requires FAISS
pip install .[faiss-cpu] # CPU-based Faiss library
pip install .[faiss-gpu] # GPU-based Faiss library
# Development tools
pip install .[dev]License
