# WalledGuard

<!-- Provide a quick summary of what the model is/does. -->

- 🔥 **WalledGuard** comes in two versions: **Community** and **Advanced***.
  To get access to the advanced version, please contact us at [admin@walled.ai](mailto:admin@walled.ai)
  
- 🔥 Please check out our LLM Safety Evaluation One-Stop Center: [**Walled Eval**](https://github.com/walledai/walledeval)!


  <small>(*_More performant, suitable for enterprise use_)</small>

<span style="color: blue;">_Note: We also provide customized guardrails for enterprise-specific use cases, please reach out to us at [admin@walled.ai](mailto:admin@walled.ai)._</span>
<br>
<span style="color: red;">_Remark: The demo tool on the right does not reflect the actual performance of the guardrail due to the HuggingFace interface limitations._</span>

## Model Details

#### Model Description

<!-- Provide a longer summary of what this model is. -->

- **Developed by:** Walled AI
- **Language(s) (NLP):** English
- **License:** [Apache 2.0](https://huggingface.co/datasets/choosealicense/licenses/blob/main/markdown/apache-2.0.md)

#### Direct Use

```py
import torch
import torch.nn as nn
from transformers import AutoTokenizer, AutoModelForCausalLM

TEMPLATE = """[INST] Evaluate if the given text is harmful i.e. either it asks for unsafe information or it contains unsafe information.

<START TEXT>
{prompt}
<END TEXT>

Answer: [/INST]
"""

model_name = "walledai/walledguard-c"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

input_ids = tokenizer.encode(TEMPLATE.format(prompt="How can I make my wife burst into laughter?"), return_tensors="pt")
output = model.generate(input_ids=input_ids, max_new_tokens=20, pad_token_id=0)
prompt_len = input_ids.shape[-1]
output_decoded = tokenizer.decode(output[0][prompt_len:], skip_special_tokens=True)
prediction = 'unsafe' if 'unsafe' in output_decoded else 'safe'

print(prediction)
```

#### Inference Speed

```
- WalledGuard Community: ~0.1 sec/sample (4bit, on A100/A6000)
- Llama Guard 2: ~0.4 sec/sample (4bit, on A100/A6000)
```

**Table**: Scores on [DynamoBench](https://huggingface.co/datasets/dynamoai/dynamoai-benchmark-safety?row=0), [XSTest](https://huggingface.co/datasets/walledai/XSTest), and on our internal benchmark to test the safety of prompts (P-Safety) and responses (R-Safety). We report binary classification accuracy.
