What is LoRA fine-tuning?

LoRA (Low-Rank Adaptation) is a parameter-efficient fine-tuning technique that trains small adapter weights instead of updating all model parameters. It reduces memory and compute requirements by 10-100x while achieving comparable performance to full fine-tuning.

When should I use LoRA vs full fine-tuning?

Use LoRA when: you have limited GPU memory, want to fine-tune large models (7B+), need multiple task-specific adapters, or want fast experimentation. Full fine-tuning is better when you have abundant compute and need maximum performance on a single task.

QLoRA combines LoRA with 4-bit quantization, enabling fine-tuning of 65B+ parameter models on a single GPU. It loads the base model in 4-bit precision and trains LoRA adapters in full precision, dramatically reducing memory requirements.

How many examples do I need for LoRA fine-tuning?

LoRA can work with as few as 100-500 high-quality examples for specific tasks. More data (1K-10K examples) improves robustness. Quality matters more than quantity—clean, diverse, representative examples outperform large noisy datasets.

What is the rank (r) parameter in LoRA?

Rank determines the size of LoRA adapter matrices. Higher rank = more parameters = more capacity but slower training. Common values: r=8 for quick experiments, r=16-32 for production, r=64+ for complex tasks. Start low and increase if needed.

Can I stack multiple LoRA adapters?

Yes, you can train separate LoRA adapters for different tasks and combine them at inference time. This enables multi-task models from a single base. Libraries like PEFT and mergekit support adapter merging and composition.

What tools support LoRA training?

Popular tools: Hugging Face PEFT (most common), Axolotl (easy configs), LLaMA-Factory (GUI), Unsloth (2x faster). All integrate with Hugging Face Transformers. Cloud platforms like Lambda Labs and RunPod offer pre-configured environments.
