Instructions to use nvidia/Nemotron-Labs-Diffusion-3B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use nvidia/Nemotron-Labs-Diffusion-3B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="nvidia/Nemotron-Labs-Diffusion-3B", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoModel
model = AutoModel.from_pretrained("nvidia/Nemotron-Labs-Diffusion-3B", trust_remote_code=True, dtype="auto")

vLLM

How to use nvidia/Nemotron-Labs-Diffusion-3B with vLLM:

Install from pip and serve model

# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "nvidia/Nemotron-Labs-Diffusion-3B"
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:8000/v1/chat/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "nvidia/Nemotron-Labs-Diffusion-3B",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/nvidia/Nemotron-Labs-Diffusion-3B

SGLang

How to use nvidia/Nemotron-Labs-Diffusion-3B with SGLang:

Install from pip and serve model

# Install SGLang from pip:
pip install sglang
# Start the SGLang server:
python3 -m sglang.launch_server \
    --model-path "nvidia/Nemotron-Labs-Diffusion-3B" \
    --host 0.0.0.0 \
    --port 30000
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:30000/v1/chat/completions" \

Field	Response
Intended Task/Domain:	Text generation
Model Type:	Transformer
Intended Users:	Generative AI creators working with conversational AI models.
Output:	Text (Responds to posed question, Stateful - remembers previous answers)
Describe how the model works:	Text input is encoded into tokens and passed into a transformer-based language model, which returns a text response.
Name the adversely impacted groups this has been tested to deliver comparable outcomes regardless of:	Not Applicable
Technical Limitations & Mitigation:	The model cannot perform long-horizon reasoning and tool calling.
Verified to have met prescribed NVIDIA quality standards:	Yes
Performance Metrics:	Accuracy, Latency, Throughput
Potential Known Risks:	In some instances, the model may think too long and struggle to derive final answers. The model's output can generate all forms of text, including what may be considered toxic, offensive, or indecent.
Licensing:	nvidia-open-model-license.
