Overview
NVIDIA Nemotron 3 Nano Omni is a full-modal reasoning model officially released and open-sourced by NVIDIA on April 28, 2026. It is the first multimodal member of the Nemotron 3 series. It adopts a hybrid MoE (Mixture of Experts) architecture with 30B total parameters / 3B activated parameters, natively supporting text, image, video, and audio inputs, with text output. The model is designed for Agentic AI scenarios, enabling AI agents to "see, hear, speak, and act" like humans, and is positioned as the sensory brain for enterprise-level AI agents.
**📌 Supplementary Information**: The Nemotron 3 series also includes **Nano / Super / Ultra three scales**, covering all deployment scenarios from edge devices to hyperscale servers. The throughput of Nano Omni is **4 times higher than Nemotron 2 Nano**. As of July 2026, there is no official release information for a new version of Nemotron 4.
Key Features
- Unified Full-Modal Reasoning: A single model handles multiple inputs such as text, images, audio, video, documents, charts, and graphical interfaces, eliminating the need to stitch together multiple independent models.
- Efficient MoE Architecture: 30B total parameters but only 3B activated, with dynamic routing calling expert modules on demand, achieving extremely high inference efficiency.
- 9x Throughput Improvement: Compared to similar open-source multimodal models, throughput performance is improved by 9 times, significantly reducing inference latency.
- 256K Ultra-Long Context: Supports a context window of up to 256K tokens, suitable for complex scenarios like long videos and long audio.
- Edge Deployment Friendly: With 4B activated parameters, it can run locally on RTX GPU laptops or embedded devices, suitable for privacy-sensitive scenarios.
- Fully Open Source: Weights and technical documentation are fully open, available on platforms like HuggingFace, allowing free deployment and fine-tuning.
Use Cases
- Building enterprise-level AI agents
- Multimodal customer service and interaction systems
- Real-time video/audio analysis on edge devices
- Local deployment in privacy-sensitive fields such as healthcare and finance
- Intelligent analysis for industrial quality inspection and video surveillance
Pros
- Unified full-modal avoids efficiency loss from switching between multiple models
- MoE architecture balances performance and inference cost
- Fully open source and supports commercial use
- Can run locally on consumer-grade GPUs
- Already adopted by enterprises such as Foxconn, Oracle, and Palantir
Pricing
Completely free and open source, weights can be obtained from HuggingFace and NVIDIA NGC. Cloud inference services can also be directly accessed via the NVIDIA API Catalog.
Summary
Nemotron 3 Nano Omni is an important foundational model launched by NVIDIA in the era of Agentic AI, filling the gap in the open-source community for enterprise-level multimodal agent backends with its extremely high inference efficiency and unified full-modal capabilities. It is suitable for enterprise developers who need local deployment and low-latency multimodal reasoning.
