hora is an open-source high-performance vector similarity search library designed for large-scale machine learning and information retrieval systems. The project focuses on approximate nearest neighbor search, a fundamental technique used in modern AI applications such as recommendation systems, image search, and semantic search engines. Hora implements multiple efficient indexing algorithms that allow systems to rapidly search through high-dimensional vectors produced by machine learning models. These vectors are commonly generated by neural networks to represent images, text, audio, or other data types in a mathematical embedding space. The library is written in Rust and emphasizes performance, safety, and efficient memory management, making it suitable for production-grade applications requiring low latency and high throughput.

Features

  • Approximate nearest neighbor search for high-dimensional vectors
  • Multiple indexing algorithms for efficient vector similarity retrieval
  • High-performance Rust implementation optimized for speed and safety
  • Support for large-scale datasets containing millions of embeddings
  • Flexible integration into machine learning and search pipelines
  • Low-latency query processing for real-time applications
