Show HN: OctaneDB – Fast, Open-Source Vector Database for Python OctaneDB is an open-source vector database for Python that focuses on ultra-fast similarity search for high-dimensional data—perfect for AI/ML, semantic search, and large-scale document or embedding retrieval. What does it do? Store, index, and search millions of embeddings (text, images, etc.) with sub-millisecond query time. Supports in-memory and efficient HDF5 persistent storage. Integrates seamlessly with sentence-transformers for automatic text embedding. Key Features: 10x faster than Pinecone or ChromaDB for vector search and batch insertions. Advanced indexing: HNSW (approximate nearest neighbor), FlatIndex Batch search, advanced metadata filtering, GPU acceleration https://ift.tt/l2QZ471 August 22, 2025 at 11:31PM
