Infinity
An AI-native database written in C++ that provides fast hybrid search across dense vectors, sparse vectors, tensors (multi-vector) and full text, for retrieval-augmented generation and similar applications.
Infinity is an AI-native database that supports dense vector, sparse vector, tensor and full-text search alongside structured data, with filtering and several reranking methods including RRF, weighted sum and ColBERT. It targets retrieval-augmented generation and related applications such as search, recommenders, question answering and conversational AI.
It ships as a single binary with no external dependencies and an intuitive Python client API, and is deployed as separate client and server processes, typically through Docker. It runs on Linux, Windows (via WSL) and macOS on x86-64 hardware with AVX2 support.
