“up to 5x faster”
NVIDIA launched Nemotron 3 Ultra, a fully open 550B mixture-of-experts model with 55B active parameters, 1M context, and day-0 support across vLLM, Modal, Together, Fireworks, and Ollama. It scored 47.7 on Artificial Analysis's Intelligence Index, making it the strongest US open-weights model tested, and matters because it pushes low-precision NVFP4 pretraining to a new scale while targeting long-running agent workloads at lower cost.
