NVIDIA Nemotron 3 Ultra Powers Faster, More Efficient AI Reasoning for Long-Running Agents
NVIDIA Nemotron 3 Ultra is NVIDIA’s latest open large language model designed to power long-running AI agents with faster reasoning, lower costs, and improved efficiency. The new model introduces advanced architectural innovations that enable developers to build more capable autonomous AI systems.
NVIDIA Nemotron 3 Ultra Delivers Faster AI Performance and Lower Costs
NVIDIA has unveiled Nemotron 3 Ultra, a 550-billion-parameter Mixture-of-Experts (MoE) model with 55 billion active parameters built specifically for agentic AI workflows.
Unlike traditional chatbots, long-running AI agents continuously plan tasks, invoke tools, coordinate with sub-agents, and maintain context over extended sessions. Nemotron 3 Ultra is optimized to handle these demanding workloads while reducing token usage and operational costs.
According to NVIDIA, the model delivers:
- Up to 5× faster inference than comparable open models.
- Up to 30% lower task completion costs.
- Support for 1 million-token context windows.
- Frontier-level reasoning and orchestration capabilities.
- Strong performance in coding, research, and enterprise AI tasks.
The model introduces several architectural innovations, including Hybrid Mamba Transformer layers, NVFP4 precision, LatentMoE routing, Multi-Token Prediction (MTP), and Multi-Teacher On-Policy Distillation (MOPD), enabling more efficient reasoning across long-running workflows.
NVIDIA is also releasing Nemotron 3.5 Content Safety for enterprise AI guardrails and Nemotron 3.5 ASR for multilingual real-time speech recognition.
The company says Nemotron 3 Ultra is fully open source, including model weights, datasets, and training recipes, allowing developers to customize and deploy the model across multiple cloud providers and inference platforms.
