NVIDIA Nemotron

NVIDIA’s Nemotron 3 Ultra enables long-running AI agents with efficient reasoning, context retention, and tool use across extended interactions.

What is NVIDIA Nemotron?

NVIDIA Nemotron 3 Ultra is a 550B-parameter Mixture-of-Experts (MoE) language model with 55B active parameters, designed specifically for orchestrating complex, long-running AI agent workflows. It combines frontier reasoning with high throughput and domain adaptability, enabling agents to maintain context, use tools, and run efficiently across many turns. Users deploy it to handle critical reasoning tasks like sustaining architectural decisions across coding sessions or synthesizing contradictory evidence from hundreds of research sources.

Application scenarios

  • Agent orchestration

    Handles the hardest calls in agent workflows, such as sustaining architectural decisions across coding sessions.

  • Long-horizon planning

    Manages complex, multi-step tasks with extended planning horizons, as shown in EnterpriseOps-Gym benchmarks.

  • Coding and terminal tasks

    Supports terminal-based coding benchmarks like Terminal-Bench 2.0 for automated development workflows.

  • Instruction following

    Maintains high accuracy on complex instruction-following tasks (IFBench: 82%).

  • Knowledge work

    Excels at professional work tasks, including search-based knowledge work (ProfBench Search: 56%).

  • Long-context processing

    Handles context windows up to 1 million tokens (Ruler @1M: 95%), enabling analysis of extensive documents or research sources.

Core Features

  • Hybrid Mamba-Transformer layers

    Combines state-space model and transformer architectures for efficient long-context handling across extended agent interactions.

  • NVFP4 quantization

    Enables deployment across multiple GPU architectures with up to 5x higher throughput compared to standard precision.

  • LatentMoE expert routing

    Optimizes which expert sub-models handle each input, improving efficiency in Mixture-of-Experts inference.

  • Multi-token prediction

    Increases generative speed for multi-turn tasks by predicting multiple tokens simultaneously.

  • Multi-Teacher On-Policy Distillation

    Continuously improves domain specialization by training with dense feedback from over ten domain-specific teacher models.

  • Open recipes, weights, and licensing

    Provides fully open model weights, training recipes, and licensing for broad adoption and fine-tuning by developers.

  • Transparent pretraining and RL data pipeline

    Offers a fully documented data pipeline for pretraining and reinforcement learning, enabling reproducibility and customization.

Target users

AI developers and engineers building long-running agent systems that require frontier reasoning, complex planning, and tool use. This includes teams working on autonomous coding assistants, research synthesis tools, chip design verification, and enterprise agent orchestration. The open model and recipes also suit researchers and organizations that need to fine-tune or domain-adapt the model for specialized workflows.

How to use NVIDIA Nemotron?

Access the model through NVIDIA’s developer portal (developer.nvidia.com). Developers can download the open model weights, training recipes, and data pipeline documentation. The model is designed for deployment across various GPU architectures using NVFP4 quantization for efficient inference. For integration into agent workflows, developers can use it as the orchestration layer for planning, reasoning, and tool calling, while pairing it with more efficient models for high-volume execution tasks.

Effect review

NVIDIA Nemotron 3 Ultra delivers strong benchmark performance across agent productivity (PinchBench: 91%), long-context handling (Ruler @1M: 95%), and instruction following (IFBench: 82%), outperforming larger models like Kimi K2.6 (1T parameters) on several key metrics. Its hybrid architecture and quantization support make it practical for real-world deployment, while the open licensing and transparent training pipeline lower barriers for customization. However, the model underperforms on long-horizon planning (EnterpriseOps-Gym: 33%) compared to GLM 5.1 (40%), suggesting room for improvement in multi-step strategic reasoning. Overall, it’s a capable, production-ready model for developers building sophisticated agent systems that need both reasoning depth and operational efficiency.
