NVIDIA has introduced Nemotron 3 Ultra, an advanced language model featuring a hybrid Mamba-Transformer architecture and a Mixture-of-Experts design with 550 billion total parameters. This model is engineered for agentic reasoning and long-horizon tasks, supporting an expansive 1-million-token context length while delivering up to six times the inference throughput of comparable open-source models. The technical report details a sophisticated training process involving NVFP4 precision pre-training on 20 trillion tokens, followed by a post-training pipeline that utilizes Supervised Fine-Tuning and Multi-teacher On-Policy Distillation. Beyond its architectural efficiency, NVIDIA is open-sourcing the model's base, post-trained, and quantized checkpoints along with its training recipes and datasets. Performance benchmarks indicate that the system maintains high accuracy while significantly reducing the computational costs and memory footprint typically associated with large-scale attention mechanisms.
