SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

PEFT enables training large language models by updating only a small subset of parameters, dramatically reducing memory and compute requirements.

Core Features & Use Cases

  • LoRA, QLoRA and other adapter methods enable efficient fine-tuning on consumer GPUs.
  • Use cases include adapting models to new tasks, multi-adapter serving, and rapid experimentation.
  • Example: fine-tune a 70B model with less than 1% trainable parameters for faster iterations.

Quick Start

Install the required Python packages and run a PEFT-based fine-tuning script on your chosen model to start.

FAQPage Schema
How do I fine-tune a 70B large language model with limited GPU memory?▼

Fine-tune a 70B large language model with limited GPU memory by using PEFT methods like QLoRA, which trains less than 1% of parameters to dramatically reduce memory and compute requirements.

What is the difference between LoRA and QLoRA for memory optimization?▼

LoRA and QLoRA are PEFT adapter methods for memory optimization, but QLoRA further reduces memory by quantizing the base model, enabling efficient fine-tuning of large language models on consumer GPUs.

Do I need bitsandbytes to use PEFT for fine-tuning?▼

Yes, you need bitsandbytes>=0.43.0 to use PEFT for fine-tuning, along with peft>=0.13.0, transformers>=4.45.0, and torch>=2.0.0 to run the memory-optimized training scripts.

Can I serve multiple task-specific adapters for the same large language model?▼

Yes, PEFT supports multi-adapter serving, allowing you to load and serve multiple task-specific adapters for the same large language model to handle different downstream tasks efficiently.

What are the limitations of using PEFT for fine-tuning large language models?▼

PEFT limitations include reliance on specific dependency versions like peft>=0.13.0 and transformers>=4.45.0, and while it saves memory, it focuses on adapter weights rather than full parameter updates.
