Low-Rank Adaptation(LoRA)
A memory-efficient fine-tuning method that trains injected parameters instead of the full model.
LoRA reduces trainable parameters by 10,000x, enabling fine-tuning on consumer GPUs.
Example
Fine-tuning a 70B model on a single RTX 4090 using LoRA instead of 8x A100 GPUs.
Frequently asked questions
