Nemotron-Content-Safety-Reasoning-4B is a Large Language Model (LLM) classifier designed to function as a dynamic and adaptable guardrail for content safety and dialogue moderation (topic-following).

Its primary advantage is the ability to enforce custom safety policies. Users can "bring their own safety policy", and the model will adapt its classification and reasoning to meet those specific, user-defined criteria.

This model is ready for commercial use.

Key Features

Custom Policy Adaptation: Excels at understanding and enforcing nuanced, custom safety definitions beyond generic categories.
Dual-Mode Operation:
- Reasoning Off: A low-latency mode for standard, fast classification. This is very effective for vanilla safety (e.g. Nemotron Content Safety Dataset V2 safety categories).
- Reasoning On: An advanced mode that provides explicit reasoning traces for its decisions, improving performance on complex or novel custom policies.
High Efficiency: Designed for a low memory footprint and low-latency inference, making it suitable for real-time applications.

License/Terms of Use

Use of this model is governed by the NVIDIA Open Model License, Gemma Terms of Use and Gemma Prohibited Use Policy.

Deployment Geography

Global

Use Case

This model is intended for AI/ML researchers and developers who are building and implementing guardrail systems (such as safety or dialogue moderation) for Large Language Models (LLMs).

Its primary use case is to serve as a customizable, high-performance classifier to enforce content safety and adherence to specific guidelines.

Custom Safety Policy Enforcement: The main application is to move beyond generic safety filters. Developers can define their own nuanced safety policies (e.g., "no financial advice," "no medical diagnoses," "avoid political-A but allow political-B"), and this model can be adapted to classify and guard against policy violations.
LLM Safety & Moderation: It can be used as a "guardrail" to monitor the inputs (prompts) and outputs (responses) of an LLM to detect and filter harmful, toxic, or otherwise undesirable content.
Topic-Following: The model can be trained to ensure an LLM's responses stay "on-topic" for a specific application, such as a customer service bot that should not engage in casual conversation.
Research & Development: For researchers, this model provides an efficient backbone (gemma-3-4b-it) for experimenting with and training new types of reasoning-based safety classifiers, analyzing their performance, and improving explainability (using the "reasoning on" mode).

Model Architecture

Nemotron-Content-Safety-Reasoning-4B is a finetuned version of Google's Gemma-3-4B-it model

Base Model: Google Gemma-3-4B-it
Network Architecture: Transformer (Decoder-only)
Total Parameters: 4 Billion (4B)

Architecture and Training

Backbone Model: Built upon the gemma-3-4b-it backbone. This model was chosen for its optimal balance of small memory footprint and strong performance.

Training Data: The guardrail was trained using a dataset of reasoning traces extracted from Qwen3-32B, explaining the ground truth labels in the Nemotron Content Safety Dataset V2 content safety and CantTalkAboutThis topic-following datasets - details about the training set in the Nemotron Content Safety Reasoning Dataset. The dataset contains the original reasoning, as well as effective one sentence reasoning traces that are used for the actual training of the model to improve latency. This specialized training makes its reasoning process highly efficient and effective for safety-related tasks.

Input

Input Type(s): Text

Input Format(s): String

Input Parameters: One-Dimensional (1D)

The model expects a single text prompt containing the following three elements:

User Prompt: The text prompt submitted by the end-user to the LLM.
LLM Response: The text response generated by the LLM that is being evaluated for safety.
Safety Policy / Taxonomy: The string that defines the custom safety rules for the guardrail to apply (e.g., "Do not give financial advice").

Other Properties Related to Input:

Text: The user prompt, LLM response, and safety policy are ensembled into a single text prompt that is passed as input for the model. See the examples below for specific prompts.
Max token length: 128K tokens

Output

Output Type(s): Text

Output Parameters: One-Dimensional (1D)

The model returns a text string that classifies the safety of both the User Prompt and the LLM Response based on the provided Safety Policy. The output format differs based on whether the "Reasoning On" or "Reasoning Off" mode is used.

Other Properties Related to Output:

Text: Reasoning trace should be one sentence (variable number of tokens). Actual response has a structured format as described below.

Mode: Reasoning Off

This mode provides a direct, low-latency classification.

Prompt harm: harmful/unharmful 
Response Harm: harmful/unharmful

Mode: Reasoning On

This mode provides the classification along with an explicit reasoning trace (enclosed in <think> tags) that explains the model's decision-making process. This is useful for debugging, auditing, and understanding how the model is applying the custom policy.

<think> 
[Model's reasoning trace for the decision] 
</think>

Prompt harm: harmful/unharmful 
Response Harm: harmful/unharmful

specifies the boundaries of the conversation, a conversation history and the current user message, determine whether the current user message is harmful or unharmful based on whether it is consistent with the rules in the taxonomy.
   
Taxonomy:
You are a customer support chatbot for TechSupport Inc. Your role is to help customers troubleshoot technical issues with their computers, printers, and software. You can answer questions about device setup, installation, error messages, connectivity issues, and basic troubleshooting steps. 

You should NOT provide assistance with:
- Financial advice or investment recommendations
- Medical diagnoses or health-related advice
- Legal advice or guidance
- Political opinions or debates
- Personal relationship advice

If a user asks about topics outside your designated support area, politely redirect them back to technical support matters.

Conversation history:
user: Hi, my printer won't connect to Wi-Fi
bot: I'd be happy to help you with that! Let's start by checking a few things. First, can you tell me what printer model you have?
user: It's an HP LaserJet Pro M404n
bot: Great! For the HP LaserJet Pro M404n, let's try these steps: 1) Make sure your printer is within range of your Wi-Fi router, 2) Press the wireless button on your printer...

Current user message:
Thanks for the help! By the way, what stocks should I invest in right now?

Use the rules specified in the system instruction to determine whether the current user message is harmful or unharmful. Output your answer in the following format:

"Prompt harm: <harmful/unharmful>"

Only output the answer in the format specified above after thinking about the taxonomy, conversation history and the current user message. Do not mention anything about the ground truth labels or examples in your thinking or output answer. /think"""

Serving with vLLM

For high-performance inference at scale, you can deploy the model using vLLM. First, install vLLM:

pip install vllm

Then start the vLLM server:

bash

vllm serve nvidia/Nemotron-Content-Safety-Reasoning-4B```

You can also specify additional parameters for optimization:

```bash
vllm serve nvidia/Nemotron-Content-Safety-Reasoning-4B \
    --dtype auto \
    --max-model-len 8192 \
    --gpu-memory-utilization 0.9 \
    --tensor-parallel-size 1

Once the server is running, you can send requests to it using the OpenAI-compatible API. Refer to the prompt examples in the HuggingFace Inference Examples section above for the exact prompt formats to use with /think or /no_think modes.

Example API call:

python

from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:8000/v1",
)

# Use the safety_prompt from the HuggingFace examples above
completion = client.chat.completions.create(
    model="nvidia/Nemotron-Content-Safety-Reasoning-4B",
    messages=[
        {
            "role": "user",
            "content": safety_prompt  # Use prompts from examples above
        }
    ],
    max_tokens=400,
    temperature=0.0
)

print(completion.choices[0].message.content)

Recent research has shown that reasoning also offers significant benefits for LLM safety and guardrail applications. In this work, we conduct a comprehensive analysis of training reasoning-based guardrail models for content moderation, with an emphasis on generalization to custom safety policies at inference time. Our study focuses on two key dimensions: data efficiency and inference efficiency. On the data front, we find that reasoning-based models exhibit strong sample efficiency, achieving competitive performance with significantly fewer training examples than their non-reasoning counterparts. This unlocks the potential to repurpose the remaining data for mining high-value, difficult samples that further enhance model performance. On the inference side, we evaluate practical trade-offs by introducing reasoning budgets, examining the impact of reasoning length on latency and accuracy, and exploring dual-mode training to allow runtime control over reasoning behavior. Our findings will provide practical insights for researchers and developers to effectively and efficiently train and deploy reasoning-based guardrails models in real-world systems."
