SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

PEFT addresses the heavy cost of fine-tuning very large language models by updating only a small subset of parameters through adapters such as LoRA and QLoRA, enabling cost-effective customization.

Core Features & Use Cases

  • Memory-efficient fine-tuning by training under 1% of parameters.
  • Support for multiple adapter methods (LoRA, QLoRA, AdaLoRA, IA3, Prefix Tuning, P-Tuning v2) and easy loading/merging of adapters for deployment.
  • Enables multi-adapter serving and model customization across tasks on large models, including deployment via merged adapters.

Quick Start

Install the peft package, configure a LoRA/QLoRA setup for your base model, then begin fine-tuning with your dataset.

Frequently Asked Questions about PEFT

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fine-tune large language models on consumer GPUs without running out of memory?

You can fine-tune large models on consumer GPUs using parameter-efficient fine-tuning, which trains less than 1% of parameters through adapters like LoRA and QLoRA to drastically reduce memory requirements.

Can I train a 70B model using LoRA adapters and quantization?

Yes, parameter-efficient fine-tuning targets large models up to 70B parameters on consumer GPUs by applying quantization and training adapters like LoRA, which updates under 1% of the model weights.

What's the best way to serve multiple customized adapters for different tasks from one base model?

Multi-adapter serving allows you to load and serve multiple customized adapters from a single base model, and you can also merge adapters directly into the model for efficient deployment.

What adapter methods are supported for parameter-efficient fine-tuning besides LoRA?

Besides LoRA and QLoRA, parameter-efficient fine-tuning supports multiple adapter methods including AdaLoRA, IA3, Prefix Tuning, and P-Tuning v2 for customizing large language models.

How do I configure target modules and training parameters for PEFT?

You configure adapters by defining target modules and training parameters directly in code using the peft library, which integrates with the compatible transformers ecosystem to start fine-tuning.
