• GPU-Powered Fine-Tuning: Optimized for NVIDIA GPUs (even 4GB VRAM)
• One-Click Workflow: Upload data → Configure → Train → Test
• Hardware-Aware: Auto-detects GPU and recommends optimal models
• No-Code UI: Beautiful React interface, no CLI or notebooks
• Multiple Providers: HuggingFace (standard) or Unsloth (2x faster)
• Advanced Strategies: SFT, QLoRA, RLHF, DPO support
• Automatic Evaluation: Built-in metrics for all tasks

📖 Supported Tasks

• Text Generation: Chatbots, instruction following, code generation, creative writing
• Summarization: Document condensing, article summarization, meeting notes
• Question Answering: RAG systems, document search, FAQ bots

🎯 Quick Start

Prerequisites

• Python 3.11.x (Python 3.12 not yet supported)
• NVIDIA GPU with 4GB+ VRAM (6GB+ recommended)
• CUDA installed and configured
• HuggingFace Account with access token (Get one here)
• Linux or Windows operating system

⚠️ macOS is NOT supported. ModelForge requires NVIDIA CUDA which is not available on macOS. Use Linux or Windows with NVIDIA GPU.

Windows Users: See Windows Installation Guide for platform-specific instructions, especially for Unsloth support.

Installation

# Install ModelForge
pip install modelforge-finetuning

# Install PyTorch with CUDA support
# Visit https://pytorch.org/get-started/locally/ for your CUDA version
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu126

Set HuggingFace Token

Linux:

export HUGGINGFACE_TOKEN=your_token_here

Windows PowerShell:

$env:HUGGINGFACE_TOKEN="your_token_here"

Or use .env file:

echo "HUGGINGFACE_TOKEN=your_token_here" > .env

Run ModelForge

modelforge run

Open your browser to http://localhost:8000 and start training!

⚠️ Important Notes

Windows Users

Unsloth provider is NOT supported on native Windows. For 2x faster training with Unsloth:

1. Option 1: WSL (Recommended) - WSL Installation Guide
2. Option 2: Docker - Docker Installation Guide

The HuggingFace provider works perfectly on native Windows.

Unsloth Constraints

When using Unsloth provider, you MUST specify a fixed max_sequence_length:

{
  "provider": "unsloth",
  "max_seq_length": 2048  // ✅ Required - cannot be -1
}

Auto-inference (max_seq_length: -1) is NOT supported with Unsloth.

📂 Dataset Format

ModelForge uses JSONL format. Each task has specific fields:

Text Generation:

{"input": "What is AI?", "output": "AI stands for Artificial Intelligence..."}
{"input": "Explain ML", "output": "Machine Learning is a subset of AI..."}

Summarization:

{"input": "Long article text...", "output": "Short summary."}

Question Answering:

{"context": "Document text...", "question": "What is X?", "answer": "X is..."}
