What problem does it solve?

Parameter-efficient fine-tuning with LoRA, QLoRA and 25+ methods lets you train large models with a fraction of parameters, dramatically reducing GPU memory and compute needs.

Core Features & Use Cases

  • Parameter-efficient adapters (LoRA, QLoRA, IA3, Prefix) enable training 7B-70B models on consumer GPUs.
  • Support for multiple adapter strategies and easy merging/serving of multiple variants.
  • Use case: quickly adapt a base model to a specialized task without retraining the full model.

Quick Start

Run a single command to begin training a LoRA adapter for your base model.

FAQPage Schema
How do I fine-tune large language models on consumer GPUs?

Fine-tune large language models on consumer GPUs by applying parameter-efficient adapters like LoRA and QLoRA. These methods train a fraction of parameters, dramatically reducing memory and compute requirements for 7B-70B models.

What is the difference between LoRA and QLoRA for model adaptation?

LoRA and QLoRA are parameter-efficient adapter strategies for adapting base models. QLoRA further reduces memory by quantizing the base model, enabling training of larger models on limited hardware compared to standard LoRA.

Do I need the PEFT library to train parameter-efficient adapters?

Yes, you need the PEFT library along with a Transformers-based workflow. Dependencies include peft, transformers, torch, and bitsandbytes to execute memory-efficient task adaptation on large models.

Can I merge and serve multiple LoRA adapters for the same base model?

Yes, you can support multiple adapter strategies and easily merge or serve multiple variants. This allows you to quickly adapt a base model to specialized tasks without retraining the full model.

What are the limitations of using parameter-efficient fine-tuning?

Parameter-efficient fine-tuning adapts models to specialized tasks by training a fraction of parameters. While it reduces costs, adapters may not capture complex knowledge shifts required for extensive domain changes compared to full retraining.

How do I start training a LoRA adapter for my base model?

Start training a LoRA adapter by running a single command to begin the process. This applies parameter-efficient methods to your base model, enabling rapid, memory-efficient task adaptation without full retraining.
