NVIDIA’s Nemotron 3 Nano, a cutting-edge reasoning model, is now accessible via Together AI, offering enhanced performance for multi-agent systems.

NVIDIA’s latest reasoning model, Nemotron 3 Nano, has been made available on Together AI, an AI Native Cloud platform, according to together.ai. This development is set to enhance the capabilities of AI engineers in building more efficient agentic systems.

Features of Nemotron 3 Nano

The Nemotron 3 Nano leverages a hybrid Mamba–Transformer and sparse Mixture-of-Experts (MoE) architecture. This design combines the strengths of Mamba layers, which efficiently manage long-range dependencies, and Transformer layers, known for general-purpose reasoning and instruction following. The sparse MoE architecture activates approximately 3 billion out of 30 billion parameters per token, optimizing speed and reducing costs.

With a 1 million token context, the model supports extensive planning, resource-heavy pipelines, and persistent agent memory. It includes open weights, training data, and recipes, making it adaptable for research, enterprise, and compliance-focused deployments. The model excels in coding, scientific reasoning, and function calling tasks.

Deployment on Together AI

Together AI is tailored for production-scale reasoning and agentic workloads, making it an ideal platform for the Nemotron 3 Nano. It offers robust performance with low latency and high throughput, ensuring fast, multi-step reasoning without bottlenecks. The platform also scales efficiently across parallel workloads, supporting multi-agent orchestration and tool-use pipelines.

Together AI emphasizes reliability, maintaining consistent performance during high traffic and ensuring high uptime. This reliability is crucial for applications involving continuous decision-making tasks. Moreover, the platform enhances cost efficiency by leveraging the model’s efficient parameter activation, lowering the cost per agent step.

The platform’s flexibility is evident in its simple, developer-friendly APIs, which include an OpenAI-compatible interface, facilitating easy integration into existing workflows and systems.

Applications and Use Cases

Nemotron 3 Nano is particularly suited for reasoning-intensive applications within the Together AI ecosystem. Its capabilities are beneficial for developing coding assistants, scientific reasoning agents, and long-context enterprise assistants. The model supports multi-step tool use and planning agents, expanding its applicability across various industries.

Developers can begin working with Nemotron 3 Nano on Together AI and engage with the community through platforms such as Discord to explore further opportunities and collaborations.
