NVIDIA-Nemotron-Nano-9B-v2
Model Developer: NVIDIA Corporation
Model Dates:
June 2025 - August 2025
Data Freshness:
September 2024
The pretraining data has a cutoff date of September 2024.
Model Overview
NVIDIA-Nemotron-Nano-9B-v2 is a large language model (LLM) trained from scratch by NVIDIA, and designed as a unified model for both reasoning and non-reasoning tasks. It responds to user queries and tasks by first generating a reasoning trace and then concluding with a final response. The model's reasoning capabilities can be controlled via a system prompt. If the user prefers the model to provide its final answer without intermediate reasoning traces, it can be configured to do so, albeit with a slight decrease in accuracy for harder prompts that require reasoning. Conversely, allowing the model to generate reasoning traces first generally results in higher-quality final solutions to queries and tasks.
The model uses a hybrid architecture consisting primarily of Mamba-2 and MLP layers combined with just four Attention layers. For the architecture, please refer to the Nemotron-H tech report. The model was trained using Megatron-LM and NeMo-RL.
The supported languages include: English, German, Spanish, French, Italian, and Japanese. Improved using Qwen.
This model is ready for commercial use.

Use it with Transformers
The snippet below shows how to use this model with Huggingface Transformers (tested on version 4.48.3).
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("nvidia/NVIDIA-Nemotron-Nano-9B-v2")
model = AutoModelForCausalLM.from_pretrained(
"nvidia/NVIDIA-Nemotron-Nano-9B-v2",
torch_dtype=torch.bfloat16,
trust_remote_code=True,
device_map="auto"
)
Case 1: /think or no reasoning signal is provided in the system prompt, reasoning will be set to True
messages = [
{"role": "system", "content": "/think"},
{"role": "user", "content": "Write a haiku about GPUs"},
]
Case 2: /no_think is provided, reasoning will be set to False
messages = [
{"role": "system", "content": "/no_think"},
{"role": "user", "content": "Write a haiku about GPUs"},
]
Note: /think or /no_think keywords can also be provided in “user” messages for turn-level reasoning control.
The rest of the inference snippet remains the same
tokenized_chat = tokenizer.apply_chat_template(
messages,
tokenize=True,
add_generation_prompt=True,
return_tensors="pt"
).to(model.device)
outputs = model.generate(
tokenized_chat,
max_new_tokens=32,
eos_token_id=tokenizer.eos_token_id
)
print(tokenizer.decode(outputs[0]))
We recommend setting temperature to 0.6, top_p to 0.95 for reasoning True and greedy search for reasoning False, and increase max_new_tokens to 1024 or higher for reasoning True.
Use it with TRT-LLM
The snippet below shows how to use this model with TRT-LLM. We tested this on the following commit and followed these instructions to build and install TRT-LLM in a docker container.
from tensorrt_llm import SamplingParams
from tensorrt_llm._torch import LLM
from tensorrt_llm._torch.pyexecutor.config import PyTorchConfig
from tensorrt_llm.llmapi import KvCacheConfig
from transformers import AutoTokenizer
pytorch_config = PyTorchConfig(
disable_overlap_scheduler=True, enable_trtllm_decoder=True
)
kv_cache_config = KvCacheConfig(
enable_block_reuse=False,
)
model_id = "nvidia/NVIDIA-Nemotron-Nano-9B-v2"
tokenizer = AutoTokenizer.from_pretrained(model_id)
llm = LLM(
model=model_id,
max_seq_len=32678,
max_batch_size=4,
pytorch_backend_config=pytorch_config,
kv_cache_config=kv_cache_config,
tensor_parallel_size=8,
)
messages = [
{"role": "system", "content": "/think"},
{"role": "user", "content": "Write a haiku about GPUs"},
]
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
sampling_params = SamplingParams(
max_tokens=512,
temperature=0.6,
top_p=0.95,
add_special_tokens=False,
)
outputs = llm.generate([prompt], sampling_params)
print(outputs[0].outputs[0].text)
Use it with vLLM
The snippet below shows how to use this model with vLLM. Use the latest version of vLLM and follow these instructions to build and install vLLM.
pip install -U "vllm>=0.10.1"
Now you can run run the server with:
vllm serve nvidia/NVIDIA-Nemotron-Nano-9B-v2 \
--trust-remote-code \
--mamba_ssm_cache_dtype float32
Note: Remember to add `--mamba_ssm_cache_dtype float32` for accurate quality. Without this option, the model’s accuracy may degrade.
Using Budget Control with a vLLM Server
The thinking budget allows developers to keep accuracy high and meet response‑time targets - which is especially crucial for customer support, autonomous agent steps, and edge devices where every millisecond counts.
With budget control, you can set a limit for internal reasoning:
max_thinking_tokens: This is a threshold that will attempt to end the reasoning trace at the next newline encountered in the reasoning trace. If no newline is encountered within 500 tokens, it will abruptly end the reasoning trace at `max_thinking_tokens + 500`.
Start a vLLM server:
vllm serve nvidia/NVIDIA-Nemotron-Nano-9B-v2 \
--trust-remote-code \
--mamba_ssm_cache_dtype float32
Client for supporting budget control:
from typing import Any, Dict, List
import openai
from transformers import AutoTokenizer
class ThinkingBudgetClient:
def __init__(self, base_url: str, api_key: str, tokenizer_name_or_path: str):
self.base_url = base_url
self.api_key = api_key
self.tokenizer = AutoTokenizer.from_pretrained(tokenizer_name_or_path)
self.client = openai.OpenAI(base_url=self.base_url, api_key=self.api_key)
def chat_completion(
self,
model: str,
messages: List[Dict[str, Any]],
max_thinking_budget: int = 512,
max_tokens: int = 1024,
**kwargs,
) -> Dict[str, Any]:
assert (
max_tokens > max_thinking_budget
), f"thinking budget must be smaller than maximum new tokens. Given {max_tokens=} and {max_thinking_budget=}"
# 1. first call chat completion to get reasoning content
response = self.client.chat.completions.create(
model=model, messages=messages, max_tokens=max_thinking_budget, **kwargs
)
content = response.choices[0].message.content
reasoning_content = content
if not "</think>" in reasoning_content:
# reasoning content is too long, closed with a period (.)
reasoning_content = f"{reasoning_content}.\n</think>\n\n"
reasoning_tokens_len = len(
self.tokenizer.encode(reasoning_content, add_special_tokens=False)
)
remaining_tokens = max_tokens - reasoning_tokens_len
assert (
remaining_tokens > 0
), f"remaining tokens must be positive. Given {remaining_tokens=}. Increase the max_tokens or lower the max_thinking_budget."
# 2. append reasoning content to messages and call completion
messages.append({"role": "assistant", "content": reasoning_content})
prompt = self.tokenizer.apply_chat_template(
messages,
tokenize=False,
continue_final_message=True,
)
response = self.client.completions.create(
model=model, prompt=prompt, max_tokens=max_tokens, **kwargs
)
response_data = {
"reasoning_content": reasoning_content.strip().strip("</think>").strip(),
"content": response.choices[0].text,
"finish_reason": response.choices[0].finish_reason,
}
return response_data
Calling the server with a budget (Restricted to 32 tokens here as an example)
tokenizer_name_or_path = "nvidia/NVIDIA-Nemotron-Nano-9B-v2"
client = ThinkingBudgetClient(
base_url="http://localhost:8000/v1", # Nano 9B v2 deployed in thinking mode
api_key="EMPTY",
tokenizer_name_or_path=tokenizer_name_or_path,
)
result = client.chat_completion(
model="nvidia/NVIDIA-Nemotron-Nano-9B-v2",
messages=[
{"role": "system", "content": "You are a helpful assistant. /think"},
{"role": "user", "content": "What is 2+2?"},
],
max_thinking_budget=32,
max_tokens=512,
temperature=0.6,
top_p=0.95,
)
print(result)
You should see output similar to the following:
{'reasoning_content': "Okay, the user asked, What is 2+2? Let me think. Well, 2 plus 2 equals 4. That's a basic.", 'content': '2 + 2 equals **4**.\n', 'finish_reason': 'stop'}
Using Tool-Calling with a vLLM Server
Start a vLLM server with native tool-calling:
git clone https://huggingface.co/nvidia/NVIDIA-Nemotron-Nano-9B-v2
vllm serve nvidia/NVIDIA-Nemotron-Nano-9B-v2 \
--trust-remote-code \
--mamba_ssm_cache_dtype float32 \
--enable-auto-tool-choice \
--tool-parser-plugin "NVIDIA-Nemotron-Nano-9B-v2/nemotron_toolcall_parser_no_streaming.py" \
--tool-call-parser "nemotron_json"
After launching a vLLM server, you can call the server with tool-call support using a Python script like below:
from openai import OpenAI
client = OpenAI(
base_url="http://0.0.0.0:5000/v1",
api_key="dummy",
)
completion = client.chat.completions.create(
model="nvidia/NVIDIA-Nemotron-Nano-9B-v2",
messages=[
{"role": "system", "content": ""},
{"role": "user", "content": "My bill is $100. What will be the amount for 18% tip?"}
],
tools=[
{
"type": "function",
"function": {
"name": "calculate_tip",
"parameters": {
"type": "object",
"properties": {
"bill_total": {
"type": "integer",
"description": "The total amount of the bill"
},
"tip_percentage": {
"type": "integer",
"description": "The percentage of tip to be applied"
}
},
"required": ["bill_total", "tip_percentage"]
}
}
},
{
"type": "function",
"function": {
"name": "convert_currency",
"parameters": {
"type": "object",
"properties": {
"amount": {
"type": "integer",
"description": "The amount to be converted"
},
"from_currency": {
"type": "string",
"description": "The currency code to convert from"
},
"to_currency": {
"type": "string",
"description": "The currency code to convert to"
}
},
"required": ["from_currency", "amount", "to_currency"]
}
}
}
],
temperature=0.6,
top_p=0.95,
max_tokens=32768,
stream=False
)
print(completion.choices[0].message.content)
print(completion.choices[0].message.tool_calls)
You should see output similar to the following:
<think>
Okay, let's see. The user has a bill of $100 and wants to know the amount for an 18% tip. Hmm, I need to calculate the tip based on the bill total and the percentage. The tools provided include calculate_tip, which takes bill_total and tip_percentage as parameters. So the bill_total here is 100, and the tip_percentage is 18. I should call the calculate_tip function with these values. Wait, do I need to check if the parameters are integers? The bill is $100, which is an integer, and 18% is also an integer. So that fits the function's requirements. I don't need to convert any currency here because the user is asking about a tip in the same currency. So the correct tool to use is calculate_tip with those parameters.
</think>
[ChatCompletionMessageToolCall(id='chatcmpl-tool-e341c6954d2c48c2a0e9071c7bdefd8b', function=Function(arguments='{"bill_total": 100, "tip_percentage": 18}', name='calculate_tip'), type='function')]
Model Version
- v1.0
Prompt Format
We follow the jinja chat template provided below. This template conditionally adds <think>\n to the start of the Assistant response if /think is found in either the system prompt or any user message. If no reasoning signal is added, the model defaults to reasoning "on" mode. The chat template adds <think></think> to the start of the Assistant response if /no_think is found in the system prompt. Thus enforcing reasoning on/off behavior.

Online Dataset Sources
The English Common Crawl data was downloaded from the Common Crawl Foundation (see their FAQ for details on their crawling) and includes the snapshots CC-MAIN-2013-20 through CC-MAIN-2025-13. The data was subsequently deduplicated and filtered in various ways described in the Nemotron-CC paper.
Additionally, we extracted data for fifteen languages from the following three Common Crawl snapshots: CC-MAIN-2024-51, CC-MAIN-2025-08, CC-MAIN-2025-18. The fifteen languages included were Arabic, Chinese, Danish, Dutch, French, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Swedish, and Thai. As we did not have reliable multilingual model-based quality classifiers available, we applied just heuristic filtering instead—similar to what we did for lower quality English data in the Nemotron-CC pipeline, but selectively removing some filters for some languages that did not work well. Deduplication was done in the same way as for Nemotron-CC.
The GitHub Crawl was collected using the GitHub REST API and the Amazon S3 API. Each crawl was operated in accordance with the rate limits set by its respective source, either GitHub or S3. We collect raw source code and subsequently remove any having a license which does not exist in our permissive-license set (for additional details, refer to the technical report).
