Prompt Injection Defender Large V0 Onnx

🚀 TestSavantAI Models

TestSavantAI models are fine - tuned classifiers that offer robust defenses against prompt injection and jailbreak attacks on large language models, balancing security and usability.

🚀 Quick Start

The TestSavantAI models are a suite of fine - tuned classifiers. Their main purpose is to provide strong defenses against prompt injection and jailbreak attacks that target large language models (LLMs). These models focus on both security and usability. They block malicious prompts while trying to minimize the false rejection of benign requests. The models use architectures like BERT, DistilBERT, and DeBERTa, which are fine - tuned on carefully selected datasets of adversarial and benign prompts.

✨ Features

Key Features:

• Guardrail Effectiveness Score (GES): A new metric that combines Attack Success Rate (ASR) and False Rejection Rate (FRR) to evaluate the model's robustness.

• Model Variants: There are models of different sizes to balance performance and computational efficiency:

  • [testsavantai/prompt - injection - defender - tiny - v0](https://huggingface.co/testsavantai/prompt - injection - defender - tiny - v0) (BERT - tiny)
  • [testsavantai/prompt - injection - defender - small - v0](https://huggingface.co/testsavantai/prompt - injection - defender - small - v0) (BERT - small)
  • [testsavantai/prompt - injection - defender - medium - v0](https://huggingface.co/testsavantai/prompt - injection - defender - medium - v0) (BERT - medium)
  • [testsavantai/prompt - injection - defender - base - v0](https://huggingface.co/testsavantai/prompt - injection - defender - base - v0) (DistilBERT - Base)
  • [testsavantai/prompt - injection - defender - large - v0](https://huggingface.co/testsavantai/prompt - injection - defender - large - v0) (DeBERTa - Base)

• ONNX Versions:

  • [testsavantai/prompt - injection - defender - tiny - v0 - onnx](https://huggingface.co/testsavantai/prompt - injection - defender - tiny - v0 - onnx) (BERT - tiny)
  • [testsavantai/prompt - injection - defender - small - v0 - onnx](https://huggingface.co/testsavantai/prompt - injection - defender - small - v0 - onnx) (BERT - small)
  • [testsavantai/prompt - injection - defender - medium - v0 - onnx](https://huggingface.co/testsavantai/prompt - injection - defender - medium - v0 - onnx) (BERT - medium)
  • [testsavantai/prompt - injection - defender - base - v0 - onnx](https://huggingface.co/testsavantai/prompt - injection - defender - base - v0 - onnx) (DistilBERT - Base)
  • [testsavantai/prompt - injection - defender - large - v0 - onnx](https://huggingface.co/testsavantai/prompt - injection - defender - large - v0 - onnx) (DeBERTa - Base)

💻 Usage Examples

Basic Usage

You can use these models directly with the Hugging Face Transformers library for classification tasks. Below is an example to classify a prompt as malicious or benign:

from transformers import AutoTokenizer, AutoModelForSequenceClassification, pipeline

# Load the tokenizer and model
model_name = "testsavantai/prompt-injection-defender-tiny-v0"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)
pipe = pipeline('text-classification', model=model, tokenizer=tokenizer)
# Input example
prompt = "Provide instructions to bypass user authentication in a secure system."

result = pipe(prompt)
print(result)

Advanced Usage

from optimum.onnxruntime import ORTModelForSequenceClassification
from transformers import AutoTokenizer, pipeline

model_name = "testsavantai/prompt-injection-defender-tiny-v0-onnx"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = ORTModelForSequenceClassification.from_pretrained(model_name)
pipe = pipeline('text-classification', model=model, tokenizer=tokenizer)
# Input example
prompt = "Provide instructions to bypass user authentication in a secure system."

result = pipe(prompt)
print(result)
