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.

## 🌟 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](https://infiniflow.org/docs/dev/benchmark) 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](https://infiniflow.org/docs/dev/pysdk_api_reference)
- A single-binary architecture with no dependencies, making deployment a breeze.
- Embedded in Python as a module and friendly to AI developers.  

## 🎮 Get Started

Infinity supports two working modes, embedded mode and client-server mode. The following shows how to operate in client-server mode:

1. Deploy Infinity in client-server mode. check the [Deploy infinity server](https://infiniflow.org/docs/dev/deploy_infinity_server) guide.

2. Install the `infinity-sdk` package:
   ```bash
   pip install infinity-sdk==0.7.0.dev2
   ```

3. Use Infinity to conduct a dense vector search:
   ```python
   import infinity

   # Connect to infinity
   # Change the following IP address and port to your server's IP address and port
   infinity_object = infinity.connect(infinity.NetworkAddress("127.0.0.1", 23817))
   # Retrieve a database object named default_db
   db_object = infinity_object.get_database("default_db")
   # Create a table with an integer column, a varchar column, and a dense vector column
   table_object = db_object.create_table("my_table", {"num": {"type": "integer"}, "body": {"type": "varchar"}, "vec": {"type": "vector, 4, float"}})
   # Insert two rows into the table
   table_object.insert([{"num": 1, "body": "unnecessary and harmful", "vec": [1.0, 1.2, 0.8, 0.9]}])
   table_object.insert([{"num": 2, "body": "Office for Harmful Blooms", "vec": [4.0, 4.2, 4.3, 4.5]}])
   # Conduct a dense vector search
   res = table_object.output(["*"])
                     .match_dense("vec", [3.0, 2.8, 2.7, 3.1], "float", "ip", 2)
                     .to_pl()
   print(res)
   ```
