microsoft/LoRA

A Python library implementing LoRA (Low-Rank Adaptation) to efficiently fine-tune large language models by significantly reducing trainable parameters and storage requirements.

Core Features

Implements LoRA for parameter-efficient fine-tuning of LLMs.

Drastically reduces the number of trainable parameters.

Minimizes storage footprint for adapted models.

Enables efficient task-switching without adding inference latency.

Achieves comparable or superior performance to full fine-tuning.

Seamless integration with PyTorch and Hugging Face models.

Detailed Introduction

LoRA (Low-Rank Adaptation) is a groundbreaking technique designed to address the challenges of fine-tuning massive Large Language Models (LLMs). This project provides `loralib`, a Python package that implements LoRA, allowing developers to adapt LLMs to specific tasks with unprecedented efficiency. By learning low-rank decomposition matrices while freezing original weights, LoRA dramatically reduces the number of trainable parameters and storage needs, facilitating rapid task-switching and deployment without compromising inference speed or performance, often surpassing traditional full fine-tuning methods.
