SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires peft>=0.13.0, transformers>=4.45.0, torch>=2.0.0, bitsandbytes>=0.43.0, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill solves the problem of efficiently fine-tuning large language models (LLMs) with limited GPU memory, while minimizing accuracy loss and enabling multi-adapter serving.

Core Features & Use Cases

  • Parameter-Efficient Fine-Tuning: Fine-tune LLMs with minimal accuracy loss, using methods like LoRA and QLoRA.
  • Memory Optimization: Train <1% of parameters on large models (7B-70B) using limited GPU memory.
  • Multi-Adapter Serving: Deploy multiple fine-tuned variants from a single base model, with each adapter optimized for a specific task.

Quick Start

Install the peft skill and fine-tune a model with LoRA: pip install peft then run python train.py --model <base_model_name> --lora-r 16 --lora-alpha 32.

FAQPage Schema
How do I fine-tune a large language model with limited GPU memory?▼

You can fine-tune large language models with limited GPU memory by using parameter-efficient methods like LoRA and QLoRA to train under 1% of parameters on models up to 70B in size.

What is the difference between LoRA and QLoRA for parameter-efficient fine-tuning?▼

Both LoRA and QLoRA enable parameter-efficient fine-tuning, but QLoRA further reduces memory requirements by quantizing the base model, making it suitable for low-memory scenarios while minimizing accuracy loss.

Can I deploy multiple fine-tuned LLM variants from a single base model?▼

Yes, you can deploy multiple fine-tuned variants from a single base model using multi-adapter serving, where each adapter is optimized for a specific task to save resources.

Does PEFT work with transformers and bitsandbytes for low-memory training?▼

Yes, PEFT integrates with transformers, torch, and bitsandbytes to enable memory-optimized training of large models, allowing you to train on limited GPU memory efficiently.

How do I start fine-tuning an LLM with LoRA using PEFT?▼

Install the PEFT package and run the training script with your base model name, specifying LoRA parameters like rank and alpha to begin the parameter-efficient fine-tuning process.

What are the limitations of using QLoRA for task-specific adaptation?▼

While QLoRA minimizes accuracy loss during parameter-efficient fine-tuning, it may still introduce slight performance trade-offs compared to full fine-tuning due to aggressive model quantization.
