Infinity
Open-source AI-native database offering very fast hybrid search over dense, sparse, tensor and full-text data for LLM apps.
What it does
Infinity is an AI-native database from InfiniFlow built for LLM and RAG applications. It provides hybrid search combining dense embeddings, sparse embeddings, tensors and full-text, with rerankers such as RRF, weighted sum and ColBERT. It emphasizes very low query latency, high throughput, a simple Python API and single-binary, dependency-free deployment.
