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

You can fine-tune large language models on memory-constrained consumer hardware by training minimal parameter subsets through LoRA and QLoRA techniques. This approach drastically reduces memory usage while enabling domain adaptation and instruction tuning.

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

LoRA and QLoRA are parameter-efficient fine-tuning techniques that train a tiny fraction of model parameters. QLoRA incorporates quantization via bitsandbytes, further reducing memory usage for high-performance model customization on consumer hardware.

Can I fine-tune a 70B parameter model on a 24GB GPU?

Yes, you can fine-tune a 70B parameter model on a single 24GB GPU using QLoRA. This technique optimizes large language model fine-tuning by training minimal parameter subsets, satisfying requirements for domain-specific instruction following without a massive compute cluster.

How do I manage multiple task-specific adapters on a single base model?

You can manage and switch multiple task-specific adapters on a single base model using multi-adapter support. This allows efficient domain adaptation without maintaining separate full model copies for each task.

What libraries do I need to run LoRA fine-tuning with transformers?

You need peft, transformers, torch, and bitsandbytes libraries to run LoRA fine-tuning. These dependencies facilitate high-performance model customization using transformers, accelerate, and bitsandbytes for memory-efficient training.

When should I use parameter-efficient fine-tuning instead of full model training?

Use parameter-efficient fine-tuning when facing high computational costs and memory requirements. LoRA and QLoRA allow you to adapt powerful models on limited GPU resources by training minimal parameter subsets for domain-specific instruction following.
