Today we're shipping Nemotron 3 Ultra. A 550B MoE frontier-intelligence open model built for long-running agents. It delivers 5x faster inference and lowers the cost of complex agentic tasks by up to 30% versus other open frontier models. Video
推荐理由:原文给出 550B 开源模型的权重、训练数据与完整配方,并说明其在长任务智能体上的吞吐表现,读者可据此判断开源前沿模型的可复现程度。
