Model Overview

Model Developer: NVIDIA Corporation

What is Nemotron?

NVIDIA Nemotron™ is a family of open models with open weights, training data, and recipes, delivering leading efficiency and accuracy for building specialized AI agents.

Quick Start

For efficient inference on DGX Spark or data center GPUs, see the NVFP4 card. The example below serves BF16 on 4× H100.

Nemotron 3.5 Super VL has configurable reasoning levels: off, on (medium), and on. Selecting on (medium) will reduce the number of tokens generated compared to on, but may impact accuracy. You can learn about the reasoning budget here!

Use Docker with NVIDIA GPU support and the vllm/vllm-openai:nightly-3f1bcfd82bb2e93fcd364fc7a5491718453a77e2 or (vllm/vllm-openai:v0.32.0) image. If the model requires authentication, set HF_TOKEN in your shell before launching the container.

bash

export MODEL=nvidia/NVIDIA-Nemotron-3.5-Super-VL-120B-A12B-BF16

bash

vllm serve $MODEL \  --served-model-name nemotron-3.5-super-vl \  --tensor-parallel-size 4 \  --trust-remote-code \  --gpu-memory-utilization=0.85 \  --allowed-local-media-path=/ \  --max-num-seqs=32 \  --limit-mm-per-prompt '{"video": 1, "image": 1}' \  --video-pruning-rate 0.5 \  --media-io-kwargs '{"video": {"fps": 2, "num_frames": 256}}' \  --enable-auto-tool-choice \  --tool-call-parser qwen3_coder \  --reasoning-parser nemotron_v3 \  --speculative_config.method mtp \  --speculative_config.num_speculative_tokens 3

Wait for the server to finish loading the model and compiling kernels, then check the endpoint:

bash

curl --fail http://localhost:8000/v1/models

All vLLM and SGLang examples use port 8000 and the API model name nemotron-3.5-super-vl. See the API Client for text, image, video, and tool-calling examples.

HLE, text-only	31.79	24.2

We evaluated Nemotron 3.5 Super on a comprehensive suite of benchmarks spanning agentic capabilities, reasoning and knowledge, multimodal, conversational ability and instruction following, long-context understanding, and multilingual performance. All evaluation results for Nemotron 3.5 Super and baselines were collected via NeMo Gym. For reproducibility purposes, more details on the evaluation settings can be found in the NeMo Gym recipes folder and the corresponding reproducibility tutorial. The published recipes specify the benchmark-specific containers, prompts, inference parameters, parser configurations, and scoring settings used to produce the results.

There were a few benchmarks that were not yet onboarded in our open source tools, and for these we used either their official open source implementation or an internal scaffolding that we plan to open source in the future: BabyVision, CharXiv-RQ, MathVision, MMLongBench-Doc, OCR-Reasoning, OCRBench-v2, V*, Video-MME-v2.

Model Architecture

Architecture Type: Mamba-2–Transformer hybrid Mixture of Experts (MoE) with Multi-Token Prediction (MTP)
Network Architecture: Nemotron Hybrid MoE with 512 routed experts per MoE layer, a C-RADIO vision encoder, and a vision-language connector
Number of Model Parameters: 120B total / 12B active

Model Design

The model combines sparse expert computation, attention, and Mamba-2 layers to support long-context processing. The vision encoder and connector turn visual inputs into representations processed by the language backbone. A shared MTP head predicts future tokens recursively for speculative decoding.

The model supports up to 1M tokens of context. The prompt, visual inputs, conversation history, tool results, and generated response share this context window. Individual deployment recipes may use a smaller context window to accommodate the available GPU memory and concurrency.

Training Methodology

Stage 1: Foundation and Multi-Token Prediction

The language backbone is initialized from Nemotron 3 Super Base. A shared MTP head is trained for 100B tokens while the backbone remains frozen, followed by 1T tokens of distillation from Nemotron 3 Ultra Base.

Stage 2: Continued Pre-Training and Mid-Training

The model undergoes 100B tokens of Indic continued pre-training, a 35B-token extension to 1M context, 67B tokens of software-engineering mid-training at 256K context, and a final 9B-token long-context recovery stage. Software-engineering data includes repositories, issue–pull-request pairs, commit diffs, build and CI logs, and agent trajectories.

Stage 3: Vision-Language Training

A C-RADIO vision encoder and connector extend the language backbone to visual inputs, including images, document pages, and video frames.

Stage 4: Supervised Fine-Tuning

A two-stage supervised fine-tuning pipeline jointly trains the language and vision components on vision, reasoning, code, tools, chat, safety, and long-context data. Training uses packed sequences of up to 524,288 tokens.

Stage 5: Reinforcement Learning and Distillation

Reinforcement learning with verifiable rewards, reinforcement learning from human feedback, and specialized teacher training improve reasoning, agentic, chat, and vision capabilities. Multi-teacher on-policy distillation consolidates these capabilities into a single model.

Stage 6: MTP Boosting

The MTP head is further trained against the frozen post-trained backbone to improve speculative-decoding acceptance.

Table with columns: Hardware, Runtime, Configuration
Hardware	Runtime	Configuration
4× H100	vLLM	Text, image, and video; TP4; MTP with 3 draft tokens
2× GB200	vLLM	Text, image, and video; TP2; MTP with 5 draft tokens

Speculative Decoding

The serving examples enable the model's native MTP head. No separate drafter download is required for these vLLM and SGLang recipes. In vLLM, num_speculative_tokens controls draft length; in SGLang, the MTP recipe uses EAGLE with speculative-eagle-topk 1.

Performance depends on hardware, request length, and concurrency. To compare with standard decoding, remove the speculative configuration while keeping the model, workload, sampling parameters, and other server settings the same.

vLLM

Use vllm/vllm-openai:nightly-3f1bcfd82bb2e93fcd364fc7a5491718453a77e2 for these commands (or vllm/vllm-openai:v0.32.0).

4× H100 (up to 1M Context Length)

Use this command if you need to serve the model with up to 1M context length.

bash

vllm serve $MODEL \  --served-model-name nemotron-3.5-super-vl \  --tensor-parallel-size 4 \  --trust-remote-code \  --async-scheduling \  --allowed-local-media-path=/ \  --max-num-seqs 32 \  --enable-mamba-shared-prefix-checkpoint \  --limit-mm-per-prompt '{"video": 1, "image": 1}' \  --video-pruning-rate 0.5 \  --media-io-kwargs '{"video": {"fps": 2, "num_frames": 256}}' \  --enable-auto-tool-choice \  --tool-call-parser qwen3_coder \  --reasoning-parser nemotron_v3 \  --speculative_config.method mtp \  --speculative_config.num_speculative_tokens 5

2× GB200 (up to 1M Context Length)

Use this command if you need to serve the model with up to 1M context length.

bash

vllm serve $MODEL \  --served-model-name nemotron-3.5-super-vl \  --tensor-parallel-size 2 \  --trust-remote-code \  --async-scheduling \  --allowed-local-media-path=/ \  --max-num-seqs 32 \  --enable-mamba-shared-prefix-checkpoint \  --limit-mm-per-prompt '{"video": 1, "image": 1}' \  --video-pruning-rate 0.5 \  --media-io-kwargs '{"video": {"fps": 2, "num_frames": 256}}' \  --enable-auto-tool-choice \  --tool-call-parser qwen3_coder \  --reasoning-parser nemotron_v3 \  --speculative_config.method mtp \  --speculative_config.num_speculative_tokens 5

For the multimodal examples, each request can contain one image and one video. The video configuration samples up to 256 frames at 2 FPS with a pruning rate of 0.5. For 1080p videos, use 1 FPS and up to 128 frames; 2 FPS and 256 frames can be used for lower-resolution video such as 720p. Start with short MP4 clips of one to two minutes.

SGLang

Use lmsysorg/sglang:v0.5.20. The example below runs on two GB200 GPUs.

bash

docker run --rm --gpus all --ipc=host \  -p 8000:8000 \  -e HF_TOKEN \  -v "$HOME/.cache/huggingface:/root/.cache/huggingface" \  --entrypoint sglang lmsysorg/sglang:v0.5.20 \  serve --model-path "$MODEL_CKPT" \  --served-model-name nemotron-3.5-super-vl \  --host 0.0.0.0 \  --port 8000 \  --trust-remote-code \  --tp-size 2 \  --reasoning-parser nemotron_3 \  --tool-call-parser qwen3_coder \  --mamba-ssm-dtype float16 \  --enable-mamba-cache-stochastic-rounding \  --mamba-cache-philox-rounds 5 \  --speculative-algorithm EAGLE \  --speculative-num-steps 5 \  --speculative-eagle-topk 1

API Client

Install the OpenAI-compatible client:

bash

pip install openai

Text and reasoning

python

from openai import OpenAI client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")model = "nemotron-3.5-super-vl" response = client.chat.completions.create(    model=model,    messages=[{"role": "user", "content": "Explain why binary search takes logarithmic time."}],    temperature=1.0,    top_p=0.95,    max_tokens=16384,    extra_body={"chat_template_kwargs": {"enable_thinking": True}},)choice = response.choices[0]if choice.finish_reason == "length":    raise RuntimeError("The response reached max_tokens; increase the output budget.")print(choice.message.content)

Set enable_thinking to False to disable reasoning. For medium reasoning effort, use {"enable_thinking": True, "medium_effort": True}. Reasoning tokens and the final answer share the max_tokens budget.

Images

Use a multimodal server configuration. The example below sends a local image as a base64 data URL.

python

import base64from pathlib import Pathfrom openai import OpenAI client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")image_bytes = Path("image.png").read_bytes()image_url = "data:image/png;base64," + base64.b64encode(image_bytes).decode() response = client.chat.completions.create(    model="nemotron-3.5-super-vl",    messages=[{"role": "user", "content": [        {"type": "text", "text": "Describe the image and any visible text."},        {"type": "image_url", "image_url": {"url": image_url}},    ]}],    temperature=1.0,    top_p=0.95,    max_tokens=16384,)if response.choices[0].finish_reason == "length":    raise RuntimeError("The response reached max_tokens; increase the output budget.")print(response.choices[0].message.content)

Video with vLLM

Use a multimodal vLLM configuration with the video sampling settings above.

python

import base64from pathlib import Pathfrom openai import OpenAI client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")video_bytes = Path("video.mp4").read_bytes()video_url = "data:video/mp4;base64," + base64.b64encode(video_bytes).decode() response = client.chat.completions.create(    model="nemotron-3.5-super-vl",    messages=[{"role": "user", "content": [        {"type": "text", "text": "Summarize the events in this video in order."},        {"type": "video_url", "video_url": {"url": video_url}},    ]}],    temperature=1.0,    top_p=0.95,    max_tokens=16384,)if response.choices[0].finish_reason == "length":    raise RuntimeError("The response reached max_tokens; increase the output budget.")print(response.choices[0].message.content)

Tool calling

The model requests a tool call; the application executes it and returns the result. This complete example uses a local inventory lookup.

python

import jsonfrom openai import OpenAI client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")model = "nemotron-3.5-super-vl"inventory = {"keyboard": 12, "monitor": 5}tools = [{"type": "function", "function": {    "name": "get_inventory",    "description": "Return the inventory count for a product.",    "parameters": {        "type": "object",        "properties": {"product": {"type": "string", "enum": ["keyboard", "monitor"]}},        "required": ["product"],        "additionalProperties": False,    },}}]messages = [{"role": "user", "content": "How many keyboards are in stock?"}] def complete(history, tool_choice="auto"):    response = client.chat.completions.create(        model=model,        messages=history,        tools=tools,        tool_choice=tool_choice,        temperature=1.0,        top_p=0.95,        max_tokens=16384,        extra_body={"chat_template_kwargs": {"enable_thinking": True}},    )    choice = response.choices[0]    if choice.finish_reason == "length":        raise RuntimeError("The response was truncated; increase max_tokens.")    return choice.message message = complete(messages)messages.append(message.model_dump(exclude_none=True))if not message.tool_calls:    print(message.content)else:    for call in message.tool_calls:        arguments = json.loads(call.function.arguments)        if (call.function.name != "get_inventory"                or not isinstance(arguments, dict)                or set(arguments) != {"product"}                or not isinstance(arguments["product"], str)                or arguments["product"] not in inventory):            raise ValueError("Invalid inventory tool call")        product = arguments["product"]        messages.append({            "role": "tool",            "tool_call_id": call.id,            "content": json.dumps({"product": product, "count": inventory[product]}),        })    print(complete(messages, tool_choice="none").content)

Crawled and Scraped from Online Sources by NVIDIA

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 used in the Nemotron-CC data pipeline. 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.

API Client

Install the OpenAI-compatible client:

bash

pip install openai

Text and reasoning

python

from openai import OpenAI client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")model = "nemotron-3.5-super-vl" response = client.chat.completions.create(    model=model,    messages=[{"role": "user", "content": "Explain why binary search takes logarithmic time."}],    temperature=1.0,    top_p=0.95,    max_tokens=16384,    extra_body={"chat_template_kwargs": {"enable_thinking": True}},)choice = response.choices[0]if choice.finish_reason == "length":    raise RuntimeError("The response reached max_tokens; increase the output budget.")print(choice.message.content)

Images

Use a multimodal server configuration. The example below sends a local image as a base64 data URL.

python

import base64from pathlib import Pathfrom openai import OpenAI client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")image_bytes = Path("image.png").read_bytes()image_url = "data:image/png;base64," + base64.b64encode(image_bytes).decode() response = client.chat.completions.create(    model="nemotron-3.5-super-vl",    messages=[{"role": "user", "content": [        {"type": "text", "text": "Describe the image and any visible text."},        {"type": "image_url", "image_url": {"url": image_url}},    ]}],    temperature=1.0,    top_p=0.95,    max_tokens=16384,)if response.choices[0].finish_reason == "length":    raise RuntimeError("The response reached max_tokens; increase the output budget.")print(response.choices[0].message.content)

Video with vLLM

Use a multimodal vLLM configuration with the video sampling settings above.

python

import base64from pathlib import Pathfrom openai import OpenAI client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")video_bytes = Path("video.mp4").read_bytes()video_url = "data:video/mp4;base64," + base64.b64encode(video_bytes).decode() response = client.chat.completions.create(    model="nemotron-3.5-super-vl",    messages=[{"role": "user", "content": [        {"type": "text", "text": "Summarize the events in this video in order."},        {"type": "video_url", "video_url": {"url": video_url}},    ]}],    temperature=1.0,    top_p=0.95,    max_tokens=16384,)if response.choices[0].finish_reason == "length":    raise RuntimeError("The response reached max_tokens; increase the output budget.")print(response.choices[0].message.content)

Tool calling

The model requests a tool call; the application executes it and returns the result. This complete example uses a local inventory lookup.

python

import jsonfrom openai import OpenAI client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")model = "nemotron-3.5-super-vl"inventory = {"keyboard": 12, "monitor": 5}tools = [{"type": "function", "function": {    "name": "get_inventory",    "description": "Return the inventory count for a product.",    "parameters": {        "type": "object",        "properties": {"product": {"type": "string", "enum": ["keyboard", "monitor"]}},        "required": ["product"],        "additionalProperties": False,    },}}]messages = [{"role": "user", "content": "How many keyboards are in stock?"}] def complete(history, tool_choice="auto"):    response = client.chat.completions.create(        model=model,        messages=history,        tools=tools,        tool_choice=tool_choice,        temperature=1.0,        top_p=0.95,        max_tokens=16384,        extra_body={"chat_template_kwargs": {"enable_thinking": True}},    )    choice = response.choices[0]    if choice.finish_reason == "length":        raise RuntimeError("The response was truncated; increase max_tokens.")    return choice.message message = complete(messages)messages.append(message.model_dump(exclude_none=True))if not message.tool_calls:    print(message.content)else:    for call in message.tool_calls:        arguments = json.loads(call.function.arguments)        if (call.function.name != "get_inventory"                or not isinstance(arguments, dict)                or set(arguments) != {"product"}                or not isinstance(arguments["product"], str)                or arguments["product"] not in inventory):            raise ValueError("Invalid inventory tool call")        product = arguments["product"]        messages.append({            "role": "tool",            "tool_call_id": call.id,            "content": json.dumps({"product": product, "count": inventory[product]}),        })    print(complete(messages, tool_choice="none").content)
