r2r 0.2.59

SciPhi R2R

The ultimate open source RAG answer engine

About

R2R was designed to bridge the gap between local LLM experimentation and scalable, production-ready Retrieval-Augmented Generation (RAG). R2R provides a comprehensive and SOTA RAG system for developers, built around a RESTful API for ease of use.

For a more complete view of R2R, check out the full documentation.

Key Features

• 📁 Multimodal Support: Ingest files ranging from .txt, .pdf, .json to .png, .mp3, and more.
• 🔍 Hybrid Search: Combine semantic and keyword search with reciprocal rank fusion for enhanced relevancy.
• 🔗 Graph RAG: Automatically extract relationships and build knowledge graphs.
• 🗂️ App Management: Efficiently manage documents and users with rich observability and analytics.
• 🌐 Client-Server: RESTful API support out of the box.
• 🧩 Configurable: Provision your application using intuitive configuration files.
• 🔌 Extensible: Develop your application further with easy builder + factory pattern.
• 🖥️ Dashboard: Use the R2R Dashboard, an open-source React+Next.js app for a user-friendly interaction with R2R.

Install

[!NOTE] Windows users are advised to use Docker to run R2R.

Installing with Pip 🐍

pip install r2r

# setup env, can freely replace `demo_vecs`
export OPENAI_API_KEY=sk-...
export POSTGRES_USER=YOUR_POSTGRES_USER
export POSTGRES_PASSWORD=YOUR_POSTGRES_PASSWORD
export POSTGRES_HOST=YOUR_POSTGRES_HOST
export POSTGRES_PORT=YOUR_POSTGRES_PORT
export POSTGRES_DBNAME=YOUR_POSTGRES_DBNAME
export POSTGRES_VECS_COLLECTION=demo_vecs

Installing with Docker 🐳

Docker allows users to get started with R2R seamlessly—providing R2R, the R2R Dashboard, and a pgvector database all in one place.

First, clone the R2R repository:

git clone https://github.com/SciPhi-AI/R2R.git
cd R2R
# for R2R CLI and Python client
pip install .

Then, run the following command to start all containers:

For hosted LLMs (e.g., OpenAI):

# Be sure to set an OpenAI API key
export OPENAI_API_KEY=sk-...
export CONFIG_NAME=default
docker-compose up -d

For local LLMs (e.g., Ollama):

export OLLAMA_API_BASE=http://host.docker.internal:11434
export CONFIG_NAME=local_ollama
docker-compose up -d

Note: Settings relating to Postgres+pgvector can be overriden by setting the appropriate environment variables before calling docker-compose.

export POSTGRES_USER=$YOUR_POSTGRES_USER
export POSTGRES_PASSWORD=$YOUR_POSTGRES_PASSWORD
export POSTGRES_HOST=$YOUR_POSTGRES_HOST
export POSTGRES_PORT=$YOUR_POSTGRES_PORT
export POSTGRES_DBNAME=$YOUR_POSTGRES_DBNAME
export POSTGRES_VECS_COLLECTION=$MY_VECS_COLLECTION
docker-compose up -d

The POSTGRES_VECS_COLLECTION defines the collection where all R2R related tables reside. This collection should be changed when selecting a new embedding model.

Start the R2R server

Serving the R2R CLI ✈️

r2r serve --port=8000

Hello r2r

Building with R2R is easy - see the hello_r2r example below:

from r2r import Document, GenerationConfig, R2R

app = R2R() # You may pass a custom configuration to `R2R`

app.ingest_documents(
    [
        Document(
            type="txt",
            data="John is a person that works at Google.",
            metadata={},
        )
    ]
)

rag_results = app.rag(
    "Who is john", GenerationConfig(model="gpt-3.5-turbo", temperature=0.0)
)
print(f"Search Results:\n{rag_results.search_results}")
print(f"Completion:\n{rag_results.completion}")
