News

• [2023.05.05] We release the paper and code of our new work Personalize Segment Anything 🔥🔥🔥, which efficiently fine-tunes Segment Anything with 10 seconds, and improves DreamBooth for better text-to-image generation.
• [2023.04.30] We noticed that GPT-4 evaluation has a strong positional bias in favor of the first response. We will soon update the paper to reveal the position bias. GPT-4 evaluation also shows a potential to automate chatbot assessment, but still requires further research. Great thanks to Canwen Xu.

Overview

Efficiency Comparison:

Model	Parameters	Storage Space	Training Time
Alpaca	7B	13G	3 Hours
LLaMA-Adapter	1.2M	4.7M	1 Hour

By inserting adapters into LLaMA's transformer, our method only introduces 1.2M learnable parameters, and turns a LLaMA into an instruction-following model within 1 hour. For stablizing training at early stages, we propose a novel Zero-init Attention with zero gating mechanism to adaptively incorporate the instructional signals. After fine-tuning, LLaMA-Adapter can generate high-quality instruction-following sentences, comparable to the fully fine-tuned Stanford Alpaca and Alpaca-Lora.

Our approach can be simply extended to Multi-modal Input Instructions. The reasoning framework of image-conditioned LLaMA-Adapter for ScienceQA is as follows, which is also shared by other modalities, such as audio and video.

Setup

Here is a from-scratch script.

conda create -n llama_adapter -y python=3.8
conda activate llama_adapter

# install pytorch
conda install pytorch cudatoolkit -c pytorch -y

# install dependency and llama-adapter
pip install -r requirements.txt
pip install -e .

Inference

Please request access to the pre-trained LLaMA from this form (official) or download the LLaMA-7B from Hugging Face (unofficial). Then, obtain the weights of our LLaMA-Adapter from here. We denote the path to the downloaded weights of LLaMA and adapters as TARGET_FOLDER and ADAPTER_PATH.

Here is an example to generate instruction-following sentences with 7B LLaMA model and our LLaMA-Adapter:

torchrun --nproc_per_node 1 example.py \
         --ckpt_dir $TARGET_FOLDER/model_size\
         --tokenizer_path $TARGET_FOLDER/tokenizer.model \
         --adapter_path $ADAPTER_PATH

Training

We release the simple fine-tuning code of LLaMA-Adapter on LLaMA-7B model at here, which is for effortless reproduction with minimal dependencies. We will soon release the fine-tuning code for LLaMA-65B and multi-model LLaMA-Adapter.

Please download the 52K instruction-following training data from Standford Alpaca, and put it under DATA_PATH. Then run:

cd alpaca_finetuning_v1

torchrun --nproc_per_node 8 finetuning.py \
         --model Llama7B_adapter \
         --llama_model_path $TARGET_FOLDER/ \
         --data_path $DATA_PATH/alpaca_data.json \
         --adapter_layer 30 \
         --adapter_len 10 \
         --max_seq_len 512 \
         --batch_size 4 \
         --epochs 5 \
         --warmup_epochs 2 \
         --blr 9e-3 \
         --weight_decay 0.02 \
         --output_dir ./checkpoint/

Comparison with Other Methods

Instruction 1:

How can I develop my critical thinking skills? Give me three suggestions.

• LLaMA-Adapter V2:

1. Read widely: Reading books, articles, and other sources of information can help you develop your critical thinking skills. By exposing yourself to different perspectives and ideas, you can learn to analyze and evaluate information more effectively.

2. Practice mindfulness: Mindfulness is the practice of being present in the moment and paying attention to your thoughts and feelings. By being more aware of your thoughts and emotions, you can better understand and evaluate them. This can help you develop a more objective and rational approach to thinking.

3. Engage in open-minded discussions: Join a discussion group or debate club where you can engage in open-minded discussions with others. This can help you develop your critical thinking skills by challenging your assumptions and encouraging you to consider different perspectives.

• LLaMA-Adapter V1:

1. Read widely and critically.
2. Engage in discussions with people who have different perspectives.
3. Ask questions and seek out answers.

Instruction 2:

As a superhero, how would you explain your origin story to a curious child?

• LLaMA-Adapter V2:

As a superhero, I have a very interesting and exciting origin story to share with you. Once upon a time, there was a young boy named John who lived in a small town. John was always curious and wanted to help others, so he spent his days exploring the world around him and learning about different cultures and people. One day, while he was out exploring, he stumbled upon a mysterious cave. Inside the cave, John found a strange device that had the power to give him incredible abilities. With these abilities, John could fly, shoot lasers from his eyes, and even turn invisible.

John knew that he had to use these powers for good, so he decided to become a superhero and use his abilities to protect his town and the people who lived there. He started to train every day, learning how to use his powers and how to fight against evil. Eventually, John became the superhero known as "The Invisible Man" and he used his powers to help others and make the world a better place.

That's my origin story, and I'm sure you'll love it!

Instruction 3:

Tell me about alpacas.

• LLaMA-Adapter: Alpacas are members of the camelid family and are native to the Andes Mountains of South America. They are typically found in herds of 10-20 animals and are known for their gentle nature and their ability to thrive in harsh climates. Alpacas are typically white or grey in color and have long, silky coats. They are also known for their ability to produce high-quality wool, which is used in the production of clothing and other products.

OTHER METHODS

• Alpaca-LoRA: Alpacas are members of the camelid family and are native to the Andes Mountains of South America. They are known for their soft, luxurious fleece, which is used to make clothing, blankets, and other items. Alpacas are herbivores and graze on grasses and other plants. They are social animals and live in herds of up to 20 individuals.

• Stanford Alpaca: Alpacas are small, fluffy animals related to camels and llamas. They are native to Peru and Bolivia, and were first domesticated around 5,000 years ago. They are kept mainly for their fine, soft fleece, which is used to make knitwear and other garments. Alpacas are herd animals and live in small family groups, led by an older male. They are highly social animals and can form strong bonds with their owners.

• text-davinci-003: Alpacas are a domesticated species of South American camelid, similar to llamas. They are native to the Andes Mountains in South America and are kept as livestock for their soft, luxurious wool. Alpacas are social animals and live in herds of up to 20 individuals. They are typically kept in small herds of two to five animals, and are relatively easy to care for. Alpacas are herbivores and feed on grass, hay, and other vegetation. They are also known for their gentle and friendly nature, making them popular as pets.
