Nemotron 3 Nano (30B A3B) is optimized for cost-efficient specialized sub-agents and runs on smaller GPU footprints with leading accuracy for targeted tasks like coding and math. Nemotron 3 Super (120B A12B) is a hybrid Mamba-Transformer MoE built for multi-agent reasoning at the highest efficiency, suitable for single data-center GPU deployments. Llama Nemotron Ultra (253B) targets data-center-scale deployments and delivers the highest reasoning accuracy for complex enterprise workflows like customer service automation and IT security.
Yes, all Nemotron model weights, datasets, and training recipes are released openly on Hugging Face under permissive commercial licenses. You can self-host them on any supported NVIDIA GPU at no licensing cost. NVIDIA also provides hosted NIM API endpoints for evaluation, and demo access via OpenRouter. The only costs are your own compute (cloud or on-prem GPUs) and any premium NVIDIA AI Enterprise support subscription if you choose it.
Nemotron models run on NVIDIA GPUs spanning edge, cloud, and data center. The Nemotron 3 Nano 30B A3B can be deployed on a single modern GPU using vLLM, SGLang, Ollama, or llama.cpp. Nemotron 3 Super 120B A12B is designed for single data-center GPUs (such as H100 or B200), while the 253B Ultra model targets multi-GPU data-center deployments. NVIDIA provides deployment cookbooks for each tier.
All three are open-weight model families, but Nemotron differentiates itself with a hybrid Mamba-Transformer MoE architecture, native NVFP4 training, and a 1M-token context window. It also ships with a deeper agentic AI toolchain — NeMo for fine-tuning, NIM microservices for deployment, and NeMo Guardrails for safety. Compared to Llama 3 or Mistral, Nemotron exposes more of the training pipeline (10T+ tokens of training data, RL trajectories, persona datasets) so teams can fully reproduce or customize the models.
NVIDIA NIM is a containerized microservice format that packages Nemotron models with optimized inference (TensorRT-LLM) and a stable production API. NIM is optional — you can deploy Nemotron with open frameworks like vLLM, SGLang, or Hugging Face transformers instead. NIM is most useful for enterprise teams that want a turnkey, GPU-accelerated endpoint with NVIDIA support; developers experimenting locally typically use Ollama or llama.cpp.
