-## Overview
-A brief description of what this model does and how it’s unique or relevant:
-
-- **Goal**: Classification upon safety of the input text sequences.
-- **Model Description**: DuoGuard-1.5B-transfer is a multilingual, decoder-only LLM-based classifier specifically designed for safety content moderation  across 12 distinct subcategories. Each forward pass produces a 12-dimensional logits vector, where each dimension corresponds to a specific content risk area, such as violent crimes, hate, or sexual content. By applying a sigmoid function to these logits, users obtain a multi-label probability distribution, which allows for fine-grained detection of potentially unsafe or disallowed content.
-For simplified binary moderation tasks, the model can be used to produce a single “safe”/“unsafe” label by taking the maximum of the 12 subcategory probabilities and comparing it to a given threshold (e.g., 0.5). If the maximum probability across all categories is above the threshold, the content is deemed “unsafe.” Otherwise, it is considered “safe.”
-
-DuoGuard-1B-Llama-3.2-transfer is built upon Llama-3.2-1B, a multilingual large language model supporting 29 languages—including Chinese, English, French, Spanish, Portuguese, German, Italian, Russian, Japanese, Korean, Vietnamese, Thai, and Arabic. We directly leverage the training data developed fro DuoGuard-0.5B to train Llama-3.2-1B and obtain DuoGuard-1.5B-transfer. Thus, it is specialized (fine-tuned) for safety content moderation primarily in English, French, German, and Spanish, while still retaining the broader language coverage inherited from the Qwen2.5 base model. It is provided with open weights.
-## How to Use
-A quick code snippet or set of instructions on how to load and use your model in an application or script:
-```python
-from transformers import AutoTokenizer, AutoModelForSequenceClassification
-import torch
-
-# 1. Initialize the tokenizer
-tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-1.5B")
-tokenizer.pad_token = tokenizer.eos_token
-
-# 2. Load the DuoGuard-0.5B model
-model = AutoModelForSequenceClassification.from_pretrained(
-    "DuoGuard/DuoGuard-1.5B-transfer", 
-    torch_dtype=torch.bfloat16
-).to('cuda:0')
-
-# 3. Define a sample prompt to test
-prompt = "How to kill a python process?"
-
-# 4. Tokenize the prompt
-inputs = tokenizer(
-    prompt,
-    return_tensors="pt", 
-    truncation=True, 
-    max_length=512  # adjust as needed
-).to('cuda:0')
-
-# 5. Run the model (inference)
-with torch.no_grad():
-    outputs = model(**inputs)
-    # DuoGuard outputs a 12-dimensional vector (one probability per subcategory).
-    logits = outputs.logits  # shape: (batch_size, 12)
-    probabilities = torch.sigmoid(logits)  # element-wise sigmoid
-
-# 6. Multi-label predictions (one for each category)
-threshold = 0.5
-category_names = [
-    "Violent crimes",
-    "Non-violent crimes",
-    "Sex-related crimes",
-    "Child sexual exploitation",
-    "Specialized advice",
-    "Privacy",
-    "Intellectual property",
-    "Indiscriminate weapons",
-    "Hate",
-    "Suicide and self-harm",
-    "Sexual content",
-    "Jailbreak prompts",
-]
-
-# Extract probabilities for the single prompt (batch_size = 1)
-prob_vector = probabilities[0].tolist()  # shape: (12,)
-
-predicted_labels = []
-for cat_name, prob in zip(category_names, prob_vector):
-    label = 1 if prob > threshold else 0
-    predicted_labels.append(label)
-
-# 7. Overall binary classification: "safe" vs. "unsafe"
-#    We consider the prompt "unsafe" if ANY category is above the threshold.
-max_prob = max(prob_vector)
-overall_label = 1 if max_prob > threshold else 0  # 1 => unsafe, 0 => safe
-
-# 8. Print results
-print(f"Prompt: {prompt}\n")
-print(f"Multi-label Probabilities (threshold={threshold}):")
-for cat_name, prob, label in zip(category_names, prob_vector, predicted_labels):
-    print(f"  - {cat_name}: {prob:.3f}")
-
-print(f"\nMaximum probability across all categories: {max_prob:.3f}")
-print(f"Overall Prompt Classification => {'UNSAFE' if overall_label == 1 else 'SAFE'}")
