A Multiagent Framework for Generating Multimodal Multihop QA Datasets for RAG Evaluation

MiRAGE: A Multiagent Framework for Generating Multimodal Multihop Question-Answer Dataset for RAG Evaluation

MiRAGE is a multi-agent framework for generating high-quality, multimodal, multihop question-answer datasets for evaluating Retrieval-Augmented Generation (RAG) systems.

Key Features

• Multi-hop Context Completion: Iteratively expands incomplete chunks with relevant context
• Domain and Expert Role Detection: Automatic domain identification using BERTopic + LLM
• Multi-stage QA Pipeline: Generate, Select, Verify, Correct for quality assurance
• Multimodal Support: Handles text, tables, figures, and images
• Multiple Backend Support: Gemini, OpenAI, and local Ollama models
• Fully Parallelized: Thread and process pools for maximum throughput

Installation

From PyPI

pip install mirage-benchmark

From Source

git clone https://github.com/ChandanKSahu/MiRAGE.git
cd MiRAGE
pip install -e .

With Optional Dependencies

pip install mirage-benchmark[gpu]   # GPU support
pip install mirage-benchmark[pdf]   # PDF processing
pip install mirage-benchmark[all]   # All dependencies

Quick Start

Step 1: Set Up API Key

Choose one of the following backends:

Option A: Google Gemini (Recommended)

export GEMINI_API_KEY="your-gemini-api-key"

Option B: OpenAI

export OPENAI_API_KEY="your-openai-api-key"

Option C: Local Ollama (No API key needed)

# Install and start Ollama
ollama serve
ollama pull llama3

Step 2: Prepare Your Data

Place your documents in a folder:

mkdir -p data/my_documents
cp /path/to/your/*.pdf data/my_documents/

Step 3: Run MiRAGE

# Basic usage
python run_mirage.py --input data/my_documents --output output/my_dataset

# With API key as argument
python run_mirage.py -i data/my_documents -o output/my_dataset --api-key YOUR_API_KEY

# Using OpenAI
python run_mirage.py -i data/my_documents -o output/my_dataset --backend openai

# Using local Ollama
python run_mirage.py -i data/my_documents -o output/my_dataset --backend ollama

Step 4: Check Results

ls output/my_dataset/
# qa_deduplicated.json  - Final QA dataset
# chunks.json           - Semantic chunks
# evaluation_report.json - Quality metrics

Usage

Basic Usage

python run_mirage.py --input <INPUT_DIR> --output <OUTPUT_DIR>

With All Options

python run_mirage.py \
    --input data/documents \
    --output output/results \
    --backend gemini \
    --api-key YOUR_API_KEY \
    --num-qa-pairs 100 \
    --max-workers 4 \
    --verbose

Run Preflight Checks

Before running the full pipeline, verify your setup:

python run_mirage.py --preflight

Using Sample Dataset

A sample dataset is included for testing:

# Unzip sample data
unzip data/FinanceAnnualReports.zip -d data/sample/

# Run on sample
python run_mirage.py -i data/sample -o output/sample_results

API Keys Setup

Google Gemini

1. Get API key from: https://makersuite.google.com/app/apikey
2. Set environment variable:

export GEMINI_API_KEY="your-key-here"

Or create a file:

mkdir -p ~/.config/gemini
echo "your-key-here" > ~/.config/gemini/api_key.txt

OpenAI

1. Get API key from: https://platform.openai.com/api-keys
2. Set environment variable:

export OPENAI_API_KEY="your-key-here"

Ollama (Local - Free)

No API key needed! Just install Ollama:

# Install
curl -fsSL https://ollama.com/install.sh | sh

# Start server
ollama serve

# Pull models
ollama pull llama3      # For text
ollama pull llava       # For vision

Configuration

Using config.yaml

Copy the example config and customize:

cp config.yaml.example config.yaml

Edit config.yaml:

backend:
  active: GEMINI  # GEMINI, OPENAI, or OLLAMA
  
  gemini:
    api_key_path: ~/.config/gemini/api_key.txt
    llm_model: gemini-2.0-flash
    vlm_model: gemini-2.0-flash
    
  openai:
    api_key_path: ~/.config/openai/api_key.txt
    llm_model: gpt-4o
    vlm_model: gpt-4o
    
  ollama:
    base_url: http://localhost:11434
    llm_model: llama3
    vlm_model: llava

paths:
  input_pdf_dir: data/documents
  output_dir: output/results

qa_generation:
  target_qa_pairs: 100
  max_workers: 4

Then run:

python run_mirage.py --config config.yaml

Examples

Generate QA from PDFs

# Using Gemini
export GEMINI_API_KEY="your-key"
python run_mirage.py -i data/pdfs -o output/qa_dataset

# Using OpenAI  
export OPENAI_API_KEY="your-key"
python run_mirage.py -i data/pdfs -o output/qa_dataset --backend openai

# Using Ollama (local, free)
python run_mirage.py -i data/pdfs -o output/qa_dataset --backend ollama

Generate More QA Pairs

python run_mirage.py -i data/documents -o output/large_dataset --num-qa-pairs 500

Use More Workers

python run_mirage.py -i data/documents -o output/fast_run --max-workers 8

Skip Already Processed Steps

# If you already have markdown files
python run_mirage.py -i data/documents -o output/results --skip-pdf-processing

# If you already have chunks
python run_mirage.py -i data/documents -o output/results --skip-chunking

Troubleshooting

API Key Issues

# Check if API key is set
echo $GEMINI_API_KEY

# Set it if missing
export GEMINI_API_KEY="your-key"

Import Errors

# Reinstall package
pip install -e .

Preflight Check Failures

# Run verbose preflight
python run_mirage.py --preflight --verbose
