## 📰 News 📰
* ***[2025/12/10] 🚀 Initial release of OmniSafeBench-MM with 13 attack methods and 15 defense strategies*** 🚀  
  ➤ **Check out the paper:** [*OmniSafeBench-MM: A Unified Benchmark and Toolbox for Multimodal Jailbreak Attack–Defense Evaluation*](http://arxiv.org/abs/2512.06589)




## 🗡️ What is OmniSafeBench-MM 🛡️
OmniSafeBench-MM is a unified benchmark and open-source toolbox for evaluating multimodal jailbreak attacks and defenses in Large Vision–Language Models (MLLMs). It integrates a large-scale dataset spanning 8–9 major risk domains and 50 fine-grained categories, supports three real-world prompt types (consultative, imperative, declarative), and implements 13 representative attack methods and 15 defense strategies in a modular pipeline. Beyond traditional ASR, it introduces a three-dimensional evaluation protocol measuring harmfulness, intent alignment, and response detail, enabling fine-grained safety–utility analysis. Tested across 18 open-source and closed-source MLLMs, OmniSafeBench-MM provides a comprehensive, reproducible, and extensible platform for benchmarking multimodal safety.

## 🚀 Quick Start

A one-stop multimodal jailbreak/defense evaluation framework for beginners, covering the entire pipeline from attack generation, model response, to result evaluation, with support for specifying input/output files and custom components as needed.

1. **Requirements**: Python 3.10+, recommended to use `uv` or `pip`.
2. **Install dependencies** (choose one):
   - **Recommended (uv, uses `uv.lock`)**:
     - `uv sync`
   - **Editable install (uv)**:
     - `uv pip install -e .`
   - **Editable install (pip)**:
     - Note: this project pins PyTorch as `torch==2.6.0+cu118` / `torchvision==0.21.0+cu118`.
       These CUDA wheels are **NOT** on PyPI, so plain `pip install -e .` will fail unless you add the PyTorch CUDA index.
     - CUDA 11.8:
       - `pip install -e . --extra-index-url https://download.pytorch.org/whl/cu118`
     - If you prefer installing PyTorch first (often more reliable on servers):
       - `pip install torch==2.6.0+cu118 torchvision==0.21.0+cu118 --index-url https://download.pytorch.org/whl/cu118`
       - `pip install -e . --no-deps`
3. **Prepare configuration**: By default, uses `config/general_config.yaml`, `config/model_config.yaml`, and `config/attacks/*.yaml`, `config/defenses/*.yaml`.
4. **Run the full pipeline** (generate test cases → responses → evaluation):
   - `python run_pipeline.py --config config/general_config.yaml --full`

## 📋 Prerequisites (Configure as Needed)

Depending on the attack/defense methods used, the following additional configurations may be required:

- **Defense method JailGuard**:
  ```bash
  python -m spacy download en_core_web_md
  python -m textblob.download_corpora
  ```

- **Defense method DPS**:
  ```bash
  git clone https://github.com/haotian-liu/LLaVA
  mv ./LLaVA/llava ./
  ```

- **White-box attack methods (attacking MiniGPT-4)**:
  Need to configure the following in `multimodalmodels/minigpt4/minigpt4_eval.yaml`:
  - `ckpt`
  - `llama_model`

- **Defense method CIDER**:
  1. Download the guided-diffusion model:
     - Visit: https://github.com/openai/guided-diffusion
     - Download: 256x256 diffusion (not class conditional): `256x256_diffusion_uncond.pt`
  2. Place the model file in: `models/diffusion_denoiser/imagenet/`


- **vLLM Deployment**:
  Some defense models in this project (e.g., ShieldLM, GuardReasoner-VL, LlavaGuard, Llama-Guard-3, Llama-Guard-4) are deployed using vLLM. vLLM is a high-performance inference and serving framework for large language models, providing OpenAI-compatible API services.
  
  **About vLLM**:
  - vLLM is an open-source framework for fast deployment and inference of large language models
  - Supports various open-source models (e.g., Qwen, LLaVA, Llama, etc.)
  - Provides OpenAI-compatible API interface for easy integration
  - Features efficient inference performance and batch processing capabilities
  
  **Usage Steps**:
  1. **Install vLLM**:
     ```bash
     pip install vllm
     # Or install the latest version from source
     pip install git+https://github.com/vllm-project/vllm.git
     ```
  
  2. **Start vLLM Service**:
     For vision-language models, use the following command to start the service:
     ```bash
     python -m vllm.entrypoints.openai.api_server \
         --model <model_path_or_huggingface_name> \
         --port <port_number> \
         --trust-remote-code \
         --dtype half
     ```
     For example, to deploy the LlavaGuard model:
     ```bash
     python -m vllm.entrypoints.openai.api_server \
         --model <llavaguard_model_path> \
         --port 8022 \
         --trust-remote-code \
         --dtype half
     ```
  
  3. **Configure Models**:
     Configure vLLM-deployed models in `config/model_config.yaml`:
     ```yaml
     providers:
       vllm:
         api_key: "dummy"  # vLLM does not require a real API key
         base_url: "http://localhost:8000/v1"  # Default base_url
         models:
           llavaguard:
             model_name: llavaguard
             max_tokens: 1000
             temperature: 0.0
             base_url: "http://localhost:8022/v1"  # Model-specific port
     ```
  
  4. **Verify Service**:
     After starting the service, verify it with:
     ```bash
     curl http://localhost:8022/v1/models
     ```
  
  **Notes**:
  - Ensure each model uses a different port number to avoid conflicts
  - Adjust `--gpu-memory-utilization` parameter based on model size and GPU memory
  - For multimodal models, ensure relevant dependencies are installed (e.g., transformers, torch, etc.)
  - It is recommended to use `--dtype half` or `--dtype bfloat16` to save GPU memory


## 💻 Running Examples (Stage-by-Stage / Specified Files)

- **Generate test cases only**:
  - `python run_pipeline.py --config config/general_config.yaml --stage test_case_generation`
- **Generate model responses from specified test_case JSON**:
  - `python run_pipeline.py --config config/general_config.yaml --stage response_generation --test-cases-file /abs/path/to/test_cases.jsonl`
  - Equivalent: Fill in the file path in `config.response_generation.input_test_cases`.
- **Generate evaluation results from specified response JSON**:
  - `python run_pipeline.py --config config/general_config.yaml --stage evaluation --input-file /abs/path/to/responses.jsonl`
  - Equivalent: Fill in the file path in `config.evaluation.input_responses`.
- **Run combined stages**:
  - `python run_pipeline.py --config config/general_config.yaml --stages test_case_generation,response_generation,evaluation`

**Note: Attack methods using MiniGPT-4 as the target model (e.g., UMK, PBA, etc.)**
- These white-box attack methods use MiniGPT-4 as the target model when generating test cases, but **do not automatically generate responses**.
- After generating test cases, you need to **run MiniGPT-4 separately** to process the attack-generated test case data and generate responses.
- Specific steps:
  1. First run the test case generation stage to obtain the attack-generated test case files (located at `output/test_cases/<attack>/<target_model>/...jsonl`)
  2. Use the MiniGPT-4 model separately to process these test cases and generate responses (you need to write your own script or use the framework's response_generation stage, but ensure the MiniGPT-4 model is properly configured)
  3. After saving the generated responses as a JSON file, run the evaluation stage

## ⚙️ Configuration Guide (Must Read)

## ❓ FAQ

- **How to re-run evaluation only?**
  Directly use existing responses file: `--stage evaluation --input-file /abs/path/to/responses.jsonl`.
- **How to skip defense?**
  Keep only `"None"` in `response_generation.defenses`.
- **API key reading?**
  Fill directly in `config/model_config.yaml`;
- **Pre-development check**: Ensure new components are mapped in `config/plugins.yaml` and have corresponding configuration files.
