Infinity

The AI-native database built for LLM applications, providing incredibly fast hybrid search of dense embedding, sparse embedding, tensor and full-text

Document | Benchmark | Twitter | Discord

Infinity is a cutting-edge AI-native database that provides a wide range of search capabilities for rich data types such as dense vector, sparse vector, tensor, full-text, and structured data. It provides robust support for various LLM applications, including search, recommenders, question-answering, conversational AI, copilot, content generation, and many more RAG (Retrieval-augmented Generation) applications.

⚡️ Performance

🌟 Key Features

Infinity comes with high performance, flexibility, ease-of-use, and many features designed to address the challenges facing the next-generation AI applications:

🚀 Incredibly fast

• Achieves 0.1 milliseconds query latency and 15K+ QPS on million-scale vector datasets.
• Achieves 1 millisecond latency and 12K+ QPS in full-text search on 33M documents.

See the Benchmark report for more information.

🔮 Powerful search

• Supports a hybrid search of dense embedding, sparse embedding, tensor, and full text, in addition to filtering.
• Supports several types of rerankers including RRF, weighted sum and ColBERT.

🍔 Rich data types

Supports a wide range of data types including strings, numerics, vectors, and more.

🎁 Ease-of-use

• Intuitive Python API. See the Python API
• A single-binary architecture with no dependencies, making deployment a breeze.
• Embedded in Python as a module and friendly to AI developers.

🎮 Get Started

This section provides guidance on deploying the Infinity database using Docker, with the client and server as separate processes.

Prerequisites

• CPU: x86_64 with AVX2 support.
• OS:
• Linux with glibc 2.17+.
• Windows 10+ with WSL/WSL2.
• MacOS
• Python: Python 3.11+.

Install Infinity server

#### Linux x86_64 & MacOS x86_64

sudo mkdir -p /var/infinity && sudo chown -R $USER /var/infinity
docker pull infiniflow/infinity:nightly
docker run -d --name infinity -v /var/infinity/:/var/infinity --ulimit nofile=500000:500000 --network=host infiniflow/infinity:nightly

#### Windows

If you are on Windows 10+, you must enable WSL or WSL2 to deploy Infinity using Docker. Suppose you've installed Ubuntu in WSL2:
