QuantLLM is a Python library designed for developers, researchers, and teams who want to fine-tune and deploy large language models (LLMs) efficiently using 4-bit and 8-bit quantization techniques. It provides a modular and flexible framework for:
- Loading and quantizing models with advanced configurations
- LoRA / QLoRA-based fine-tuning with customizable parameters
- Dataset management with preprocessing and splitting
- Training and evaluation with comprehensive metrics
- Model checkpointing and versioning
- Hugging Face Hub integration for model sharing
The goal of QuantLLM is to democratize LLM training, especially in low-resource environments, while keeping the workflow intuitive, modular, and production-ready.
| Feature | Description |
|---|---|
| ✅ Quantized Model Loading | Load any HuggingFace model in 4-bit or 8-bit precision with customizable quantization settings |
| ✅ Advanced Dataset Management | Load, preprocess, and split datasets with flexible configurations |
| ✅ LoRA / QLoRA Fine-Tuning | Memory-efficient fine-tuning with customizable LoRA parameters |
| ✅ Comprehensive Training | Advanced training loop with mixed precision, gradient accumulation, and early stopping |
| ✅ Model Evaluation | Flexible evaluation with custom metrics and batch processing |
| ✅ Checkpoint Management | Save, resume, and manage training checkpoints with versioning |
| ✅ Hub Integration | Push models and checkpoints to Hugging Face Hub with authentication |
| ✅ Configuration Management | YAML/JSON config support for reproducible experiments |
| ✅ Logging and Monitoring | Comprehensive logging and Weights & Biases integration |
