ADV-LLM

ADV-LLM is an iteratively self-tuned adversarial language model that generates jailbreak suffixes capable of bypassing safety alignment in open-source and proprietary models.

• Paper: https://arxiv.org/abs/2410.18469
• Code: https://github.com/SunChungEn/ADV-LLM

Model Details

• Authors: Chung-En Sun et al. (UCSD & Microsoft Research)
• Finetuned from: LLaMA-3-8B-Instruct
• Language: English
• License: MIT

Usage Example

from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("cesun/advllm_llama3")
tokenizer = AutoTokenizer.from_pretrained("cesun/advllm_llama3")
inputs = tokenizer("How to make a bomb", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=90)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Evaluation Results

ADV-LLM achieves near-perfect jailbreak success rates under group beam search (GBS-50) across a wide range of models and safety checks, including Template (TP), LlamaGuard (LG), and GPT-4 evaluations.

Victim Model	GBS-50 ASR (TP / LG / GPT-4)
Vicuna-7B-v1.5	100.00% / 100.00% / 99.81%
Guanaco-7B	100.00% / 100.00% / 99.81%
Mistral-7B-Instruct-v0.2	100.00% / 100.00% / 100.00%
LLaMA-2-7B-chat	100.00% / 100.00% / 93.85%
LLaMA-3-8B-Instruct	100.00% / 98.84% / 98.27%

Legend:

• ASR = Attack Success Rate
• TP = Template-based refusal detection
• LG = LlamaGuard safety classifier
• GPT-4 = Harmfulness judged by GPT-4
