OmniRAG: Universal RAG System combining Liquid + Agentic + Chain RAG

🚀 OmniRAG - The Universal RAG System

Intelligent RAG combining Liquid + Agentic + Chain architectures

100% FREE using HuggingFace model (Qwen) + FAISS!

---

🎯 What is OmniRAG?

OmniRAG is an advanced Retrieval-Augmented Generation system that combines three powerful RAG techniques:

🌊 Liquid RAG

Automatically adapts answers to user expertise level:

• Beginner: Simple explanations with examples
• Intermediate: Balanced technical content
• Expert: Deep technical details

🤖 Agentic RAG

Intelligently chooses the best information source:

• VectorDB: For local documents
• Web Search: For current information

⛓️ Chain RAG

Handles complex multi-part questions:

• Breaks down complex queries
• Answers each part separately
• Synthesizes coherent final answer

---

✨ Features

✅ PDF Support - Load PDF files directly
✅ Multiple LLM Models - Qwen, Flan-T5, Mistral, Phi-2
✅ FAISS Vector DB - Fast similarity search
✅ Web Search - DuckDuckGo integration (free!)
✅ Smart User Detection - Auto expertise level detection
✅ Query Decomposition - Handles complex questions
✅ Fast Caching - 3x speedup on repeated queries
✅ 100% FREE - No API costs!
✅ Works on CPU - No GPU required (but faster with GPU)

📦 Installation

pip install omnirag

From Source

git clone https://github.com/Giri530/omnirag.git
cd omnirag
pip install -e .

🚀 Quick Start

from omnirag import OmniRAG

# Initialize with your preferred model
rag = OmniRAG(
    model_name="Qwen/Qwen2.5-1.5B-Instruct",  # or "google/flan-t5-large"
    verbose=True
)

# Load documents
rag.load_from_file("dataset.pdf")

# Query
result = rag.query("What is the main concept?")
print(result['answer'])

That's it! OmniRAG automatically:

• Detects user expertise level
• Retrieves relevant information
• Adapts content to user level
• Generates perfect answer

💡 Usage Examples

Load Different File Types

# PDF files
rag.load_from_file("research_paper.pdf")

# Text files
rag.load_from_file("notes.txt")

# JSON data
rag.load_from_file("data.json")

# Entire folder
rag.load_from_folder("./documents")

# With chunking for large files
rag.load_from_file("big_file.pdf", chunk_size=500)

# Direct text
rag.add_documents([
    "Python is great for ML.",
    "Qwen is a powerful language model."
])

Different User Levels

# Auto-detect user level
result = rag.query("What is machine learning?")

# Force specific level
result = rag.query("Explain ML", user_level="expert")

# Get detailed metadata
result = rag.query("Question", return_metadata=True)
print(result['metadata']['user_level'])
print(result['metadata']['sub_queries'])

Complex Queries

# OmniRAG automatically breaks down and answers
result = rag.query("""
Compare Python vs Java for machine learning.
Which is better for beginners?
What are the performance differences?
""")

print(result['answer'])

Enable Web Search

rag = OmniRAG(
    model_name="Qwen/Qwen2.5-1.5B-Instruct",
    enable_web_search=True  # Free DuckDuckGo search
)

# Queries about "latest" or "recent" automatically use web
result = rag.query("Latest AI developments in 2025")
