Summary
NVIDIA has announced Nemotron 3 Ultra, a 550-billion-parameter open-weight Mixture-of-Experts language model (with 55 billion active parameters per token) designed specifically for long-running AI agents, tool-heavy workflows, coding copilots, research agents, and complex enterprise automations. The model positions NVIDIA as a competitor in the frontier-model space, moving beyond its traditional GPU hardware business into advanced AI software with an open-weight approach.

· 3 pulledNVIDIA's new Nemotron 3 Ultra isn't just another big language model announcement; it's NVIDIA stepping squarely into the frontier-model arena with an open-weight system built from the ground up for long-running AI agents, not just chatbots.
It's a 550-billion-parameter Mixture-of-Experts model (with 55 billion parameters active at any given token) that NVIDIA is positioning as an open, high-speed reasoning engine for tooling-heavy workflows, coding copilots, research agents, and complex enterprise automations.
What makes Nemotron 3 Ultra interesting is not only its size, but what it represents — NVIDIA taking the company beyond GPUs and into true frontier-model territory.
