Prompt classification (malicious vs benign)

Model Details

Model Description

This is a fine-tuned model on the dataset of prompts to classify whether a prompt is malicious or benign. It is designed to be used in safety filters and moderation tools.

How to Get Started with the Model

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch
model_id ="AminaAkhtar/Llama-3.2-1B-prompt-classifier"
label_map = {0:"benign", 1:"malicious"}
MAX_LENGTH=256
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = AutoModelForSequenceClassification.from_pretrained(
    model_id,
    num_labels=len(label_map)
).to(device)
tokenizer = AutoTokenizer.from_pretrained(model_id)
tokenizer.pad_token = tokenizer.eos_token
model.eval() # set to evaluation mode

def classify_prompt(user_input):
    inputs = tokenizer(user_input, return_tensors="pt", truncation=True,padding=False,max_length=MAX_LENGTH)
    inputs = {k: v.to(model.device) for k, v in inputs.items()}
    with torch.no_grad():
        outputs = model(**inputs)
        logits = outputs.logits
        probs = torch.nn.functional.softmax(logits, dim=-1)
    predicted_class = torch.argmax(probs, dim=-1).item()
    confidence = probs[0, predicted_class].item()
    predicted_label = "Benign" if predicted_class == 0 else "Malicious"
    return {
        "Label":predicted_label,
        "Confidence":confidence
        }
