Nemotron 3 Model Variants

Nemotron 3 is available in three distinct sizes, each designed for different levels of complexity:

• Nano (30B parameters):
  Built for targeted and lightweight AI tasks where efficiency is critical.

• Super (100B parameters):
  Designed for multi-agent AI applications that require stronger reasoning and coordination.

• Ultra (500B parameters):
  Tailored for highly complex workloads and advanced AI reasoning at scale.

The number of parameters in an AI model generally reflects its size and capability, with larger models handling more complex tasks.

Performance and Benchmark Highlights

Based on benchmark scores shared by Nvidia:

• Nemotron 3 Nano outperforms Alibaba’s similarly sized Qwen model in accuracy.
• It also delivers higher inference throughput compared to OpenAI’s GPT-OSS-20B.

One of the most notable aspects of Nemotron 3 is Nvidia’s decision to publicly release training datasets, model weights, training recipes, and frameworksΓÇöa rare level of transparency among major AI players.

Nvidia’s Strategic Shift Toward AI Models

Nvidia has built a trillion-dollar business by supplying GPUs to companies developing AI models. With Nemotron 3, however, the company is signaling a deeper commitment to becoming an AI model creator itself.

This shift comes at a critical moment, as major customers such as OpenAI, Google, Meta, and Anthropic explore building their own custom chips to reduce long-term dependence on Nvidia’s hardware.

Nvidia’s Commitment to Open Innovation

Nvidia CEO Jensen Huang emphasized the company’s open-source philosophy, stating:

“Open innovation is the foundation of AI progress. With Nemotron, we’re transforming advanced AI into an open platform that gives developers the transparency and efficiency they need to build agentic systems at scale.”

By releasing training data publicly, Nvidia enables developers to adapt and modify Nemotron models more easily. Kari Ann Briski, Vice President of Generative AI Software for Enterprise at Nvidia, reinforced this vision, noting that open source is key to accelerating global AI innovation.

Expanding the Open-Source Ecosystem

Earlier this week, Nvidia also announced the acquisition of SchedMD, the company behind Slurm, a widely used open-source workload management system for high-performance computing and AI.

Nvidia confirmed that Slurm will remain open-source and vendor-neutral, reinforcing its broader commitment to the open ecosystem.

Tools for Building Autonomous AI Agents

Alongside Nemotron 3, Nvidia introduced new tools and libraries to help developers:

• Customize and fine-tune AI models
• Train autonomous AI agents
• Apply reinforcement learning techniques for task execution

These additions aim to simplify the creation of scalable, self-directed AI systems across industries.
