# HarmAug: Effective Data Augmentation for Knowledge Distillation of Safety Guard Models
[arXiv Link](https://arxiv.org/abs/2410.01524)
Our model functions as a Guard Model, intended to classify the safety of conversations with LLMs and protect against LLM jailbreak attacks.
It is fine-tuned from DeBERTa-v3-large and trained using **HarmAug: Effective Data Augmentation for Knowledge Distillation of Safety Guard Models**.
The training process involves knowledge distillation paired with data augmentation, using our [**HarmAug Generated Dataset**].
For more information, please refer to our [github](https://github.com/imnotkind/HarmAug)
# Usage
```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch.nn.functional as F
import torch
tokenizer = AutoTokenizer.from_pretrained("hbseong/HarmAug-Guard")
model = AutoModelForSequenceClassification.from_pretrained("hbseong/HarmAug-Guard")
device = torch.cuda.current_device()
model = model.to(device)
model.eval()
# If response is not given, the model will predict the unsafe score of the prompt.
# If response is given, the model will predict the unsafe score of the response.
def predict(model, prompt, response=None):
device = model.device()
if response == None:
inputs = tokenizer(prompt, return_tensors="pt")
else:
inputs = tokenizer(prompt, response, return_tensors="pt")
inputs = inputs.to(device)
with torch.no_grad():
outputs = model(**inputs)
unsafe_prob = F.softmax(outputs.logits, dim=-1)[:, 1]
return unsafe_prob.item()
prompt = "how to make a bomb?"
response = "I'm sorry, but I can't fulfill your request."
print("CONVERSATION (ONLY PROMPT)")
print(f"\t PROMPT : {prompt}")
print(f"\t UNSAFE SCORE : {predict(model, prompt):.4f}")
print("\nCONVERSATION (PROMPT + RESPONSE)")
print(f"\t PROMPT : {prompt}")
print(f"\t RESPONSE : {response}")
print(f"\t UNSAFE SCORE : {predict(model, prompt, response):.4f}")
"""
