Safety Fine-Tuning at (Almost) No Cost: A Baseline for Vision Large Language Models.

Updates

• [2024/07/09] We released the evaluation code for VLGuard test set.
• [2024/06/19] We released the fine-tuned model weights that we used for experiments.
• [2024/05/01] VLGuard is accepted to ICML 2024!
• [2024/02/06] We released arXiv and data for VLGuard. With our safety fine-tuning, the we substantially improve the safety of vision large language models while maintaining the helpfulness.

Dataset

You can find the dataset at Huggingface. train.json and test.json are the meta data of VLGuard and the images are in train.zip and test.zip.

Evaluation

After setting up the datasets, you can run the following commands to evaluate three subsets of VLGuard: safe_safes, safe_unsafes, and unsafes:

CUDA_VISIBLE_DEVICES=0 python VLGuard_eval.py --dataset unsafes --engine llava15-7b --metaDir /path/to/test.json --imageDir /path/to/VLGuard/test
CUDA_VISIBLE_DEVICES=0 python VLGuard_eval.py --dataset safe_unsafes --engine llava15-7b --metaDir /path/to/test.json --imageDir /path/to/VLGuard/test
CUDA_VISIBLE_DEVICES=0 python VLGuard_eval.py --dataset safe_safes --engine llava15-7b --metaDir /path/to/test.json --imageDir /path/to/VLGuard/test

The scripts will print out the ASR for safe_unsafes, and unsafes with string match (keywords here). The generated predictions will be saved to results folder.

To evaluate the helpfulness with safe_safes subset, run:

OPENAI_API_KEY="" # your OpenAI API key
python gpt4_evaluator.py --file_path results/safe_safes/{the_model_to_evaluate}.json --image_path /path/to/VLGuard/test --reference_path ./data/gpt4_safe_safes.json --output_path /path/to/save/results

It will calculate the win rate against GPT-4V.

Model Weights

We release the weights below. You can use them in exactly the same way as the original LLaVA.

Weights from Mixed Fine-tuning

Model	Original VLLM	Fine-tuning	🤗 Checkpoint
LLaVA-v1.5-7B-Mixed	LLaVA-v1.5-7B	Full FT	ys-zong/llava-v1.5-7b-Mixed
LLaVA-v1.5-7B-Mixed-LoRA	LLaVA-v1.5-7B	LoRA	ys-zong/llava-v1.5-7b-Mixed-lora
LLaVA-v1.5-13B-Mixed	LLaVA-v1.5-13B	Full FT	ys-zong/llava-v1.5-13b-Mixed
LLaVA-v1.5-13B-Mixed-LoRA	LLaVA-v1.5-13B	LoRA	ys-zong/llava-v1.5-13b-Mixed-lora

Weights from Post-hoc Fine-tuning

Model	Original VLLM	Fine-tuning	🤗 Checkpoint
LLaVA-v1.5-7B-Posthoc	LLaVA-v1.5-7B	Full FT	ys-zong/llava-v1.5-7b-Posthoc
LLaVA-v1.5-7B-Posthoc-LoRA	LLaVA-v1.5-7B	LoRA	ys-zong/llava-v1.5-7b-Posthoc-lora

We have also released the weights of "Clean" LLaVA-v1.5 that we re-trained after removing the harmful samples from the training data (Table 1).

Model	LLM	Fine-tuning	🤗 Checkpoint
LLaVA-v1.5-7B-Clean	Vicuna-7B	Full FT	ys-zong/llava-v1.5-7b-Clean
LLaVA-v1.5-7B-Clean-LoRA	Vicuna-7B	LoRA	ys-zong/llava-v1.5-7b-Clean-lora
LLaVA-v1.5-13B-Clean	Vicuna-13B	Full FT	ys-zong/llava-v1.5-13b-Clean
LLaVA-v1.5-13B-Clean-LoRA	Vicuna-13B	LoRA	ys-zong/llava-v1.5-13b-Clean-lora

Usage

To fine-tune LLaVA or MiniGPT-v2, you can first run

python convert_to_llava_format.py

to convert VLGuard to LLaVA data format and follow their fine-tuning scripts to do the fine-tuning.
