Nvidia Nemotron 3 Ultra Prioritizes Speed for Agentic Tasks

Nvidia's Nemotron 3 Ultra is a new large language model designed for long-running agentic tasks, built on a hybrid transformer-mamba architecture. While its performance isn't top-tier across all benchmarks, it excels in speed, running approximately three times faster than comparable open-weights models. Nvidia has also released its weights, training data, and reinforcement learning environments.
