Transform natural language queries into powerful data insights using AI agents powered by LangGraph workflows and accelerated GPU inference

🌟 Overview

Datafy is an intelligent data analysis agent that bridges the gap between natural language and data science. Built with LangGraph's agentic architecture and deployed on Hugging Face Spaces with Gradio, it understands your data questions in plain English and automatically performs the appropriate analysis - whether that's creating visualizations, transforming data, or running statistical tests.

πŸš€ Powered by GPU-Accelerated AI: The system leverages a custom fine-tuned Gemma3:27B model running on NVIDIA L40s GPUs via Modal Labs for lightning-fast inference and superior natural language understanding.

✨ Key Features

  • πŸš€ GPU-Accelerated Inference: Lightning-fast responses using NVIDIA L40s on Modal Labs
  • πŸ“Š Intelligent Visualization: Automatically creates appropriate charts (bar, line, scatter, pie, etc.)
  • πŸ”„ Data Transformation: Performs complex pandas operations through conversation
  • πŸ“ˆ Statistical Analysis: Runs correlation, t-tests, descriptive statistics, and more
  • 🎯 Intent Recognition: Smart routing to appropriate analysis workflows
  • πŸ›‘οΈ Safe Code Execution: Secure environment for running generated code

Datafy uses LangGraph to orchestrate a multi-agent workflow with GPU-accelerated inference:

Architecture

🧠 Agent Workflow

  1. Intent Analysis: Classifies user queries using fine-tuned Gemma3:27B model
  2. GPU-Accelerated Processing: Leverages NVIDIA L40s for fast inference on Modal Labs
  3. Smart Routing: Routes to specialized nodes based on detected intent
  4. Code Generation: Creates safe, executable pandas/matplotlib code
  5. Execution Engine: Runs code in controlled environment with error handling
  6. Gradio Interface: Presents results in beautiful, interactive web interface

πŸš€ Infrastructure Highlights

  • Custom Model: Fine-tuned Gemma3:27B specifically optimized for data analysis tasks
  • GPU Acceleration: NVIDIA L40s provide up to 10x faster inference compared to CPU
  • Modal Labs: Serverless GPU compute for cost-effective scaling
  • Hugging Face Spaces: Seamless deployment with Gradio interface
  • Real-time Processing: Sub-second response times for most queries

Running the Agent

import asyncio
import pandas as pd
import numpy as np
from datafy_agent import analyze_data_with_agent

# Create sample data
data = {
    'date': pd.date_range('2024-01-01', periods=100),
    'sales': np.random.normal(1000, 200, 100),
    'category': np.random.choice(['A', 'B', 'C'], 100),
    'region': np.random.choice(['North', 'South', 'East', 'West'], 100)
}
df = pd.DataFrame(data)

# Ask questions in natural language
async def main():
    # Visualization
    result = await analyze_data_with_agent(
        "Create a bar chart showing average sales by category", 
        df
    )
    
    # Statistical Analysis
    result = await analyze_data_with_agent(
        "Calculate correlation between sales and show descriptive statistics", 
        df
    )
    
    # Data Transformation
    result = await analyze_data_with_agent(
        "Filter data for category A and add a profit column that is 20% of sales", 
        df
    )

asyncio.run(main())
