Show HN: A GPU-accelerated binary vector index

Operating in show hn launch, A GPU-accelerated binary vector index operates.

Profile

This is a vector index I built that supports insertion and k-nearest neighbors (k-NN) querying, optimized for GPUs. It operates entirely in CUDA and can process queries on half a billion vectors in under 200 milliseconds. The codebase is structured as a standalone library with an HTTP API for remote access. It’s intended for high-performance search tasks—think similarity search, AI model retrieval, or reinforcement learning replay buffers. The codebase is located at https://github.com/rodlaf/BinaryGPUIndex.

Its activity falls under show hn launch; the profile below is assembled from public directory data.

The company is listed at the Show HN launch stage of development.
