Xeon CPUs (2nd generation and newer).\n\nSVS offers a fully-featured and yet simple Python API, compatible with most standard libraries.\nSVS is written in C++ to facilitate its integration into performance-critical applications.\n\n## Performance\n\nSVS provides state-of-the-art performance and accuracy [[ABHT23]](#1) for billion-scale similarity search on\n[standard benchmarks](https://intel.github.io/ScalableVectorSearch/benchs/index.html).\n\nFor example, for the standard billion-scale [Deep-1B](http://sites.skoltech.ru/compvision/noimi/) dataset,\ndifferent configurations of SVS yield significantly increased performance (measured in queries per second, QPS) with a smaller memory footprint (horizontal axis) than the alternatives[^1]:\n\n\u003cp align=\"center\"\u003e\n\u003cimg src=\"./docs/figs/SVS_performance_memoryfootprint.png\" height=80% width=80%\u003e\n\u003c/p\u003e\n\nSVS is primarily optimized for large-scale similarity search but it still offers [state-of-the-art performance\nat million-scale](https://intel.github.io/ScalableVectorSearch/benchs/small_scale_benchs.html).\n\nBest performance is obtained with 4th generation (Sapphire Rapids) by making use of Intel(R) AVX-512 instructions,\nwith excellent results also with 2nd and 3rd Intel \u0026reg; Xeon \u0026reg; processors (Cascade Lake\nand Ice Lake).\n\nPerformance will be degraded if Intel(R) AVX-512 instructions are not available.\nA warning message will appear when loading the SVS Python module if the system does not support\nIntel(R) AVX-512 instructions.\n\n## Key Features\n\nSVS supports:\n* Similarity functions: Euclidean distance, inner product, cosine similarity.\n* Vectors with individual values encoded as: float32, float16, uint8, int8.\n* Vector compression (including Locally-adaptive Vector Quantization [[ABHT23]](#1))\n* Optimizations for Intel \u0026reg; Xeon \u0026reg; processors:\n  - 2nd generation (Cascade Lake)\n  - 3rd generation (Ice Lake)\n  - 4th generation (Sapphire Rapids)\n\nSee [Roadmap](https://intel.github.io/ScalableVectorSearch/roadmap.html) for upcoming features.\n\n\n## Documentation\n\n[SVS documentation](https://intel.github.io/ScalableVectorSearch) includes getting started tutorials with [installation instructions for Python](https://intel.github.io/ScalableVectorSearch/start.html#installation) and [C++](https://intel.github.io/ScalableVectorSearch/start_cpp.html#building) and step-by-step search examples, an API reference, as well as several guides and benchmark comparisons.\n\n## References\nReference to cite when you use SVS in a research paper:\n\n```\n@article{aguerrebere2023similarity,\n        title={Similarity search in the blink of an eye with compressed indices},\n        volume = {16},\n        number = {11},\n        pages = {3433--3446},\n        journal = {Proceedings of the VLDB Endowment},\n        author={Cecilia Aguerrebere and Ishwar Bhati and Mark Hildebrand and Mariano Tepper and Ted Willke},\n        year = {2023}\n}\n```\n\n\u003ca id=\"1\"\u003e[ABHT23]\u003c/a\u003e\nAguerrebere, C.;
