Nvidia's Nemotron 3 Ultra Emerges as Top US Open AI Model, Yet China Maintains Lead

["In a significant milestone for the US AI landscape, Nvidia's Nemotron 3 Ultra has been recognized as the most capable open AI model from the United States to date, according to benchmark platform Artificial Analysis. This achievement marks a notable advancement in the development of artificial intelligence models, with Nemotron 3 Ultra boasting roughly 550 billion total parameters, of which about 55 billion are active at any given time.", 'The Nemotron 3 Ultra has secured a score of 48 points on the Artificial Analysis intelligence ranking, significantly outpacing other open US models. Notable mentions include Gemma 4 31B with a score of 39, Nemotron 3 Super with 36 points, and gpt-oss-120b with 33 points.

Despite this impressive performance, Nemotron 3 Ultra still falls short of the top open models from China, with Kimi K2.6 leading the pack at 54 points. The current strongest closed model, Opus 4.8, holds a commanding lead with 61 points.', 'In terms of performance, Nemotron 3 Ultra also demonstrates remarkable efficiency on provider DeepInfra, delivering more than 300 tokens per second, as reported by Artificial Analysis. In comparison, similarly sized models from DeepSeek or Moonshot manage only 50 to 100 tokens per second.

Nvidia has announced plans to release Nemotron 3 Ultra on June 4, making it available on platforms such as Hugging Face, OpenRouter, and others.', "The emergence of Nemotron 3 Ultra as a leading open AI model from the US highlights Nvidia's significant contributions to the field of artificial intelligence. While the model sets a new standard for US-developed AI, it also underscores the competitive landscape of global AI development, with China currently holding the lead in this rapidly evolving sector."]
