NVIDIA officially launched its new multimodal reasoning model, Nemotron 3 Nano Omni, yesterday. It deeply integrates text, vision, and speech capabilities into a single model system and is currently avAIlable for free.
As the latest member of the NEMOtron 3 family, Nemotron 3 Nano Omni can process diverse inputs including text, images, audio, video, documents, charts, and graphical user interfaces, and ouTPUts in text form. Furthermore, the model dynamically ACTivates expert networks according to different tasks and modalities, delivering strong multimodal perception while maintaining high throughput. This enables overall throughput up to 9 times that of comparable open multimodal models.
The model currently ranks among the top five on document intelligence benchmarks such as MMlongbench-Doc and OCRBenchV2. For video and audio underStanding tasks, it has secured first place on DailyOmni and VoiceBench, surpassing Qwen3-Omni-30B-A3B-Thinking and Gemini 2.5 Flash. Beyond accuracy, MediaPerf data shows it achieves the highest throughput in multi-task scenarios and the lowest inference cost for video-level annotation tasks.
Regarding the training dataset, Hugging Face indicates that Nemotron 3 Nano Omni was improved using Qwen3-VL-30B-A3B-Instruct, Qwen3.5-122B-A10B, Qwen3.5-397B-A17B, Qwen2.5-VL-72B-Instruct, and gpt-oss-120b.
According to real-world tests by overseas users, the Nemotron 3 Nano Omni model identifies video content rapidly and accurately, parsing speech videos swiftly to extract key Information. It can answer detailed questions related to specific topics within a person's speech, with responses closely matching the original content. It can also read and parse complex technical documentation, tackling hardcore technical questions about model training. Its overall comprehension, multimodal information processing, and professional content interpretation are highly impressive.

Rapid Video Understanding and Precise Segment Localization
In a practical test, an overseas blogger uploaded a three-minute-plus speech video by Jensen Huang from Nvidia GTC 2026 and directly asked the model about its content. Nemotron 3 Nano Omni completed the joint understanding of visuals and audio within just a few seconds, not only accurately summarizing the core points of the speech but also pointing out key information in specific contexts.
When the blogger further asked, "What did Jensen Huang say specifically about the leaderboards?" the model, leverAGIng the existing video context, quickly located the relevant segment and provided a more Detailed answer, demonstrating continuous memory and cross-modal retrieval capabilities for long videos.
The blogger also input Nemotron 3 Nano Omni's technical documentation directly into the model and asked it to explain the training methodology. When switching from video to text-based information sources, the model seamlessly adapted, parsing complex technical details within the Same reasoning Framework and sorting out key logic including the Mixture-of-Experts architecture, data, and training processes.
The primary APPlication scenarios for Nemotron 3 Nano Omni include computer-use Agents navigating graphical interfaces, document Intelligence for enterprise analytics and compliance workflows, and audio-video understanding for customer service and research applications. The model offers open weights, datasets, and training techniques, and can be deployed on local systems, in data centers, and in cloud environments to meet regulatory, sovereign, or data localization requirements.
Early adopters include Aible, Foxconn, Palantir, and H Company, while companies like Dell Technologies, DocuSign, Infosys, and Oracle are evaluating the model. The Nemotron 3 model series has surpassed 50 million downloads over the past year.
9x Throughput Compared to Open Multimodal Models
A core highlight of Nemotron 3 Nano Omni is its hybrid Mixture-of-Experts architecture, efficient spatiotemporal visual processing, and comprehensive multimodal capabilities. It dynamically activates expert networks based on different tasks and modalities, ensuring strong multimodal perception while maintaining high throughput, resulting in overall throughput up to 9 times that of similar open multimodal models.
The innovative hybrid MoE core architecture deeply fuses Mamba layers with Transformer layers. The Mamba layers enhance sequence processing efficiency and memory utilization, while the Transformer layers guarantee precise reasoning computation. This fused design not only significantly boosts data processing throughput but also improves memory and computational efficiency by up to 4 times, making it highly adaptable for sub-agent roles.
For video reasoning at the same interaction threshold, Nemotron 3 Nano Omni sustains a higher total throughput, providing an effective system capacity increase of approximately 9.2x compared to alternative open omni models. For multi-document reasoning at the same interaction threshold, it achieves an effective system capacity improvement of approximately 7.4x. Multimodal accuracy has improved on industry-leading benchmarks from the earlier Nemotron Nano VL V2 to Nemotron 3 Nano Omni.
An open-source model Integrating Multimodal Processing in a Unified Architecture
The open-source AI model sector for agentic reasoning is currently experiencing a concentrated surge, with increasingly fierce market competition: Meta's Llama series has long held a leading position in the open-source large language model arena; Google's Gemini focuses on cloud-based, ultra-large-scale multimodal capabilities to build a differentiated advantage; OpenAI's GPT series consistently serves as a benchmark in the commercial field; and DeepSeek's newly released V4-Pro and V4-Flash last week, with their hybrid attention architecture, specifically optimize long-cycle agent tasks, further enriching the market supply.
The core differentiation of Nemotron 3 Nano Omni lies not in single-point performance breakthroughs but in its exclusive combination of four key advantages: unified visual, audio, and text multimodal perception within a single model; high energy efficiency of the Mixture-of-Experts design suitable for edge deployment; open-weight, open-source availability; and a full commercial use license. Currently, no competing product offers all these features simultaneously. Comparable products have their own shortcomings: google's edge model Gemini Nano is not open source, and the multimodal version of Meta's Llama cannot integrate audio processing capabilities within a unified architecture.
Conclusion: A Key Move to Perfect NVIDIA's AI Layout
The strategic impact of this model extends far beyond the product itself. If Nemotron 3 Nano Omni becomes the mainstream choice for agent deployment, NVIDIA will achieve a trinity of inference GPU hardware, optimized acceleration software frameworks, and in-house upper-layer models. Competitors building on NVIDIA's ecosystem will further deepen hardware dependency; even if rivals independently develop models, the training process will remain reliant on NVIDIA's GPU computing power. As the era of Agentic AI accelerates, NVIDIA's core goal is not single-point monopoly but penetrating every critical layer of the industry and building irreplaceable standing.
