infiniflow/infinity
The AI-native database built for LLM applications, providing incredibly fast hybrid search of dense vector, sparse vector, tensor (multi-vector), and full-text.
Supports structured data filtering alongside vector and text search, with advanced reranking via RRF, weighted sum, and ColBERT. Built as a single-binary deployment with no external dependencies, embedding directly as a Python module for seamless LLM application integration. Achieves 0.1ms query latency on million-scale datasets and 1ms full-text search on 33M documents via SIMD-optimized indexing (AVX2).
