Jensen Huang took the stage at Computex 2026 in Taipei and did what he does best: unveiled a massive new AI model while wearing a leather jacket. The Nemotron 3 Ultra, packing roughly 500 to 550 billion parameters, is now the crown jewel of Nvidia’s open AI model family.
The keynote, delivered on June 1, 2026, at the Taipei Music Center, positioned Nvidia not just as a chipmaker but as a full-stack AI platform company.
What Nemotron 3 Ultra actually does
The Ultra’s 500-550 billion parameter framework is designed specifically for advanced reasoning and planning, including agentic workflows — AI systems that plan, execute, and iterate on multi-step tasks with minimal human oversight.
The Ultra sits at the top of a three-tier Nemotron 3 family. The Nano variant is already available for lighter workloads. The Super model, launched in March 2026 with 120 billion parameters, targets mid-range enterprise applications.
