LoRA (Low-Rank Adaptation)

Efficient fine-tuning technique that trains small adapter layers instead of full models.

In Simple Terms

Efficient fine-tuning technique that trains small adapter layers instead of full models.

What is LoRA (Low-Rank Adaptation)?

LoRA (Low-Rank Adaptation) is a parameter-efficient fine-tuning technique that freezes the original model weights and trains small adapter matrices instead. This reduces memory requirements and training time dramatically—fine-tuning that once required multiple GPUs can be done on a single consumer card. LoRA adapters are small files (typically 10-100MB) that can be swapped in and out, enabling multiple customizations from one base model. It's become the standard approach for custom model training.

Frequently Asked Questions

How much does LoRA reduce training costs?
—often 10x or more reduction in GPU memory and time. A 7B model LoRA can train on 8GB VRAM in hours instead of needing enterprise hardware.
Does LoRA affect quality?
LoRA can achieve results comparable to full fine-tuning for many tasks. Very specialized behaviors might benefit from full fine-tuning, but LoRA is usually sufficient.
Can I combine multiple LoRAs?
Yes, LoRAs can be merged or used together, though combining too many may degrade quality. Tools like LoRA composer help manage multiple adapters.
