rapidsai/cuvs

Implements approximate nearest neighbors (ANN) and clustering algorithms optimized for NVIDIA GPUs, built on the RAPIDS RAFT library for high-performance ML primitives. Supports multiple language bindings (Python, C++, C, Rust) and integrates with downstream databases and ML frameworks for semantic search, RAG, and graph construction. Features state-of-the-art algorithms like CAGRA for index building and search with automatic optimization across CUDA versions and GPU architectures.
