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.
