Today, we are excited to announce the day-zero availability of NVIDIA Nemotron 3 Ultra on Amazon SageMaker JumpStart.

With this launch, you can now deploy the Nemotron 3 Ultra model using a one-click deployment experience. Nemotron 3 Ultra is an open model built for frontier reasoning and orchestration in long-running autonomous agents, delivering 5x faster inference and up to 30% lower cost for agentic workloads. Nemotron 3 Ultra is optimized for the NVFP4 format, which makes the model much faster and cost effective to host.

Overview of NVIDIA Nemotron 3 Ultra

NVIDIA Nemotron 3 Ultra is an open large language model with 550 billion total parameters and 55 billion active parameters. It is built on a hybrid Transformer-Mamba Mixture-of-Experts (MoE) architecture, designed to deliver frontier intelligence at a fraction of the compute cost of dense models of equivalent quality.
