RagBuilder is a toolkit that helps you create optimal Production-ready Retrieval-Augmented-Generation (RAG) setup for your data automatically. By performing hyperparameter tuning on various RAG parameters (Eg: chunking strategy: semantic, character etc., chunk size: 1000, 2000 etc.), RagBuilder evaluates these configurations against a test dataset to identify the best-performing setup for your data. Additionally, RagBuilder includes several state-of-the-art, pre-defined RAG templates that have shown strong performance across diverse datasets. So just bring your data, and RagBuilder will generate a production-grade RAG setup in just minutes.

Features

• Hyperparameter Tuning: Efficiently identify optimal RAG configurations (combination of granular parameters like chunking strategy, chunking size, embedding models, retriever types etc.) using Bayesian optimization
• Pre-defined RAG Templates: Use state-of-the-art templates that have demonstrated strong performance across various datasets.
• Evaluation Dataset Options: Choose to generate a synthetic test dataset or provide your own.
• Automatic Reuse: Automatically re-use previously generated synthetic test data when applicable.
• Easy-to-use Interface: Intuitive UI to guide you through setting up, configuring, and reviewing your RAG configurations.

Installation

Option 1: Install using install script:

Note: For GraphRAG, Neo4J Graph Database details must be added in the .env file. For spinning up a local Neo4J Graph Database refer to repo https://github.com/KruxAI/neo4j-docker

Mac

curl -fsSL https://install.ragbuilder.io/mac | bash

Windows

curl -fsSL https://install.ragbuilder.io/win

Run Install.bat from the command prompt

install.bat

Set your OpenAI API key

Make sure your OpenAI API key is available by setting it as an environment variable. In MacOS and Linux, this is the command:

export OPENAI_API_KEY=XXXXX

and on Windows it is

set OPENAI_API_KEY=XXXXX

Now, run ragbuilder on your command line:

ragbuilder

This will start the Ragbuilder Uvicorn app and open the browser. If the browser window doesn't open automatically, go to http://localhost:8005/ in your browser to access the RagBuilder dashboard.

Option 2: Using Prebuilt Docker Image

Using Docker Compose

1. Pull the repo. This will spin up RAGBuilder and neo4J database needed for GraphRAG.

git clone https://github.com/KruxAI/ragbuilder.git

2. Copy the .env-Sample file to .env File

cp .env-Sample .env

3. Edit the .env file to add the necessary keys

4. Start RagBuilder App

docker-compose up -d

5. Once the services are up, you can access your application via http://localhost:55003

Using Docker Commands

1. Pull docker image from Docker hub

docker pull ashwinzyx/ragbuilder:latest

2. Run the Docker Container. Create .env as below and use it while running the container. The env file must be in the same directory where the docker command is being run

Mac

docker run -it -v "$(pwd):/ragbuilder" --env-file .env -p 55003:8005 ashwinzyx/ragbuilder:latest

Windows

docker run -d -v %cd%:/ragbuilder --env-file .env -p 55003:8005 ashwinzyx/ragbuilder

OR

Provide env variables using command line

docker run  -p 55003:8005  -e OPENAI_API_KEY=sk-....

This will start the Ragbuilder Uvicorn app and open the browser. If the browser window doesn't open automatically, go to http://localhost:55003/ in your browser to access the RagBuilder dashboard.

Note: If you are creating your own synthetic dataset for evaluation, save the csv file in the same directory where the docker run command is being executed and provide the file name only

Quickstart Guide

Getting started is super easy. To create a new project,

1. Click New Project to start building your RAG.
2. Description: Describe your use-case. Let's specify "Q&A Chatbot" as the description for our demo.
3. Source Data: Specify the path to your source data. This could be a URL, local directory or local file path. For the sake of our demo, let's specify the URL: https://lilianweng.github.io/posts/2023-06-23-agent/
4. Select Ragbuilder options:
   • Use Pre-defined RAG Templates - When selected, this'll include pre-defined RAG configuration templates that have demonstrated strong performance across various datasets and related use-cases. These templates will be evaluated against your data, providing you with performance metrics for each pre-defined configuration.
   • Create Custom RAG Configurations - When selected, this will generate multiple RAG configurations based on detailed parameters like chunking strategy, chunking size, embedding model, retriever type etc. With this option, it is recommended that you opt for the Bayesian optimization option to efficiently identify the near-optimal RAG configuration for your data. More about this in a bit.*
5. Next, in order to tailor your RAG configurations, you can unselect any specific options you wish to exclude (For eg: Unselecting "Chunking Strategy: Character" will exclude all RAG configurations that have the CharacterTextSplitter). For best results, you may want to leave all settings unchanged. But for our Quickstart demo, we will unselect everything except the below:
   • Chunking strategy: Markdown
   • Embedding model: text-embedding-3-large
   • Retriever: Vector DB - Similarity Search
   • Top k: 5
   • LLM: GPT-3.5 Turbo
6. Select optimization approach:
   • Bayesian optimization (Recommended): Bayesian optimization is a strategy for the optimization of objective functions that are expensive to evaluate. It is particularly useful in scenarios where the function to be optimized is unknown and expensive to compute, such as in hyperparameter tuning for machine learning models or optimizing engineering designs. This is perfect for RAG where we have multiple moving parts, each with multiple parameters
   • Run all Combinations: This option runs all possible combinations of the options selected, offering a comprehensive performance analysis of all RAG configurations for your dataset. This option is appropriate if you have selected fewer number of options. Otherwise, this option can be resource intensive as it may yield hundreds or even thousands of unique configurations to compare. [Note]: This may take several minutes to complete.
7. Next, in the Evaluation dataset options, you have the option to:
   • Use Existing Synthetic Test Data: If synthetic test data was previously generated for your dataset, this option will appear alongside the path of the existing test data.
   • Generate Synthetic Test Data from My Dataset: Create a new synthetic test dataset based on your existing data.
   • Provide a Manually Created Test Dataset: Use your own test dataset file (CSV format with "question" and "ground_truth" columns). For our demo, let's go ahead and create synthetic test data by selecting the Generate Synthetic Test Data** option.
8. Before running the tool, let's review all your selections:
9. Review all the selections and click Confirm
10. After processing we should see the dashboard with the results.
11. Click the View Code snippet option in the results screen to get the code snippet of the desired RAG configuration. And voila, you've cut down several weeks/months of effort manually creating and evaluating different RAG configurations for your dataset.

Usage Analytics

We collect basic usage metrics to understand how our tool is performing for users. Specifically, we track the number of runs initiated and how many completed successfully. As a startup, being data-driven is crucial for us, which is why we monitor these metrics. Rest assured, we do not collect any personal data or information that could identify you, your company, or access your data. You can see exactly what we track by reviewing the code here and here.
