NVIDIA Nemotron 3 Nano Omni model now available on Amazon SageMaker JumpStart

Today, we are excited to announce the day zero availability of NVIDIA Nemotron 3 Nano Omni on Amazon SageMaker JumpStart. This multimodal model from NVIDIA combines video, audio, image, and text understanding into a single, efficient architecture, enabling enterprise customers to build intelligent applications that can see, hear, and reason across modalities in one inference pass.

In this post, we walk through the model architecture and key capabilities of Nemotron 3 Nano Omni, explore the enterprise use cases it unlocks, and show you how to deploy and run inference using Amazon SageMaker JumpStart.

Overview of NVIDIA Nemotron 3 Nano Omni

NVIDIA Nemotron 3 Nano Omni is an open, multimodal large language model with 30 billion total parameters and 3 billion active parameters (30B A3B). It is built on a Mamba2 Transformer Hybrid Mixture of Experts (MoE) architecture, combining three core components:

1. Nemotron 3 Nano LLM as the language backbone
2. CRADIO v4-H as the vision encoder for image and video understanding
3. Parakeet as the speech encoder for audio transcription and comprehension

This unified architecture processes video, audio, images, and text as input and generates text as output. It supports a 131K token context length, chain of thought reasoning, tool calling, JSON output, and word level timestamps for transcription tasks. The model is available in FP8 precision on SageMaker JumpStart, delivering an optimal balance of accuracy and efficiency for enterprise workloads. It is licensed under the NVIDIA Open Model Agreement for commercial use.Enterprise agent workflows are inherently multimodal. Agents must interpret screens, documents, audio, video, and text, often within the same reasoning loop. Today, most agentic systems stitch together separate models for vision, speech, and language. This approach increases latency through repeated inference passes, complicates orchestration and error handling, fragments context across modalities, and amplifies cost and failure modes over time.

Nemotron 3 Nano Omni solves this by functioning as the multimodal perception and context sub-agent in a system of agents. It provides the agent system with eyes and ears: reading screens, interpreting documents, transcribing speech, and analyzing video, all while maintaining a converged multimodal context across reasoning loops.Nano Omni understands screens, documents, audio, and video in a single reasoning loop. This replaces fragmented model stacks and simplifies agent workflow design significantly. For anyone building agentic architectures, this collapses inference hops, orchestration logic, and cross-model synchronization overhead into a single model call.The model accepts the following input types:

Enterprise use cases

The multimodal capabilities of Nemotron 3 Nano Omni make it a powerful, flexible model choice for enterprise use cases.

Computer use agents

Nemotron 3 Nano Omni powers the perception loop for agents navigating graphical user interfaces. It reads screens, understands UI state over time, and validates outcomes, while execution agents handle the actions. This collapses vision and reasoning into a single loop, eliminating the need for split perception pipelines. Practical applications include incident management dashboards, agentic search, browser automation, and email workflow agents.

Document intelligence

The model interprets documents, charts, tables, screenshots, and mixed media inputs, enabling agents to reason across visual structure and text content coherently. This is critical for enterprise analysis and compliance workflows involving contracts, statements of work, financial documents, and scientific literature.

Audio and video understanding agents

For customer service, research, and monitoring workflows, Nemotron 3 Nano Omni maintains continuous audio and video context. It ties together what was said, shown, and documented into a single reasoning stream instead of disconnected summaries. This enables applications such as meeting recording analysis, media and entertainment asset management, drive-thru order verification, and customer service video review (for example, verifying package delivery at a given address via OCR).

Getting started with SageMaker JumpStart

You can deploy Nemotron 3 Nano Omni through Amazon SageMaker JumpStart in a few steps. SageMaker JumpStart provides one-click deployment of foundation models with optimized inference containers, removing the need to manage infrastructure, configure serving frameworks, or handle model artifact downloads.

Prerequisites

Before you begin, make sure you have:

Deploy using SageMaker Studio

1. Open Amazon SageMaker Studio
2. In the left navigation pane, choose JumpStart
3. Search for Nemotron 3 Nano Omni
4. Select the model card and choose Deploy
5. Configure your instance type and deployment settings
6. Choose Deploy to create the endpoint

Deploy using the SageMaker Python SDK

You can also deploy programmatically using the SageMaker Python SDK:

from sagemaker.jumpstart.model import JumpStartModel

model = JumpStartModel(
  model_id="huggingface-vlm-nvidia-nemotron3-nano-omni-30ba3b-reasoning-fp8",
  role="<your_sagemaker_execution_role>",
)

predictor = model.deploy(
  accept_eula=True,
)

Run inference: Image understanding

Once deployed, you can send multimodal requests to the endpoint. The following example shows how to send an image understanding request:

import base64

def encode_image(image_path):
  with open(image_path, "rb") as f:
    return base64.b64encode(f.read()).decode("utf-8")

image_b64 = encode_image("example.jpg")

payload = {
  "messages": [{ 
    "role": "user", 
    "content": [ 
      {"type": "text", "text": "Describe this image in detail."},
      {"type": "image_url", 
       "image_url": {"url": f"data:image/jpeg;base64,{image_b64}"}},
    ],
  }],
  "max_tokens": 1024,
  "temperature": 0.2,
}

response = predictor.predict(payload)
print(response["choices"][0]["message"]["content"])

Run inference: Video understanding with reasoning

import base64

def encode_video(video_path):
  with open(video_path, "rb") as f:
    return base64.b64encode(f.read()).decode("utf-8")

video_b64 = encode_video("meeting_recording.mp4")

payload = { 
  "messages": [{ 
    "role": "user", 
    "content": [ 
      {"type": "video_url", 
       "video_url": {"url": f"data:video/mp4;base64,{video_b64}"}},
      {"type": "text",
       "text": "Summarize the key discussion points."},
    ],
  }],
  "max_tokens": 20480,
  "temperature": 0.6,
  "top_p": 0.95,
}

response = predictor.predict(payload)
print(response["choices"][0]["message"]["content"])

Run inference: Audio transcription

import base64

def encode_audio(audio_path): 
  with open(audio_path, "rb") as f: 
    return base64.b64encode(f.read()).decode("utf-8")

audio_b64 = encode_audio("customer_call.wav")

payload = { 
  "messages": [{ 
    "role": "user", 
    "content": [ 
      {"type": "audio_url", 
       "audio_url": {"url": f"data:audio/wav;base64,{audio_b64}"}},
      {"type": "text", 
       "text": "Transcribe this audio and identify key action items."},
    ],
  }],
  "max_tokens": 1024,
  "temperature": 0.2,
}

response = predictor.predict(payload)
print(response["choices"][0]["message"]["content"])

Recommended inference parameters

The following table contains the recommended hyperparameter values for Omni inference requests. The values change depending on the inference mode.

For tasks that involve reasoning and complex understanding, we recommend enabling thinking mode. For transcription and straightforward tasks, instruct mode (with thinking disabled) provides faster responses.

Clean up

To avoid incurring unnecessary charges, delete the SageMaker endpoint when you are done:

predictor.delete_endpoint()
