Lightning-4b - Your Local data analysis agent

Overview

Lightning-4b is a language model specifically designed and trained for data analysis tasks on local devices. With just a laptop (fully tested on an M4 MacBook Air with 16GB RAM), you can process data without ever sending it to major LLM provider.

What it can do

Data visualization
Table joins
t-tests
Unlimited rows, 30+ tables analyzed simultaneously

What it cannot do

Business reasoning or management decision-making advice
Multi-turn analysis

To use this model, install quelmap on your device.
Quelmap is an open-source data analysis assistant with every essential features like data upload and an built-in python sandbox.
For installation instructions, see the Quick Start.

Performance

This model was trained specifically for use with quelmap.
It was evaluated using a sample database and 122 analysis queries, and achieved performance surpassing models with 50x more parameters.

For details about the model and its training process, see the Lightning-4b Details page.

Running Model on your machine

You can easily install Lightning-4b and quelmap by following the Quick Start.

Lightning-4b has multiple quantization versions depending on your hardware.
It runs smoothly on laptops, and on higher-spec machines it can handle more tables (30+ tables) and longer chat histories.
