Jensen Huang announced at GTC Taipei 2026 that the Agentic AI era has arrived, shifting AI from content generation to autonomous task execution. NVIDIA launched infrastructure products like Vera Rubin and Vera CPU, driving a computing paradigm shift where AI becomes a direct generator of profit and GDP.

NVIDIA today launches Nemotron 3 Ultra, a 550B-parameter open model built on the same architecture as Nemotron 3 Super, optimized for long-running AI agents. It employs LatentMoE to quadruple the number of experts at the same inference cost, introduces multi-token prediction to boost single-user inference speed, and is released under the Linux Foundation’s Open MDW license to enable enterprise deployment.

NVIDIA introduces the 550B-parameter Neotron 3 Ultra, a mixture-of-experts agent model trained for task orchestration, outperforming many trillion-parameter open agents on benchmarks, with full data and recipe transparency to enable enterprise on-prem deployment and fine-tuning.

Nemotron 3 Ultra is NVIDIA's latest open-source sparse mixture of experts model with 550 billion total parameters and 55 billion active parameters, designed for agentic use cases; the article demonstrates steps to build an autonomous research agent with NemoHermes, including configuring an NVIDIA API key to use build.nvidia.com endpoints, selecting Ultra as the inference model, and completing a simplified auto-research task (e.g., optimizing NanoChat) to produce real optimization results.

NVIDIA releases Cosmos 3 (omnimodal world models), Nemotron 3 Ultra (550B LLM), and RTX Spark, driving open physical AI, with Cosmos 3 achieving SOTA in Text2Image and Image2Video.

Nemotron 3 Ultra is NVIDIA's new open model, based on SSM and Mixture of Experts hybrid architecture, 5x faster and 30% cheaper than the best open models.

NVIDIA unveiled major advancements at COMPUTEX, including RTX Spark for local AI agents on Windows, Vera CPU designed for AI agents with 1.8x performance boost, Cosmos 3 open model for robotics and autonomous driving, and Nemotron 3 Ultra, a 550B-parameter open-weight model competing with top models like Kimi K2.6 and Qwen 3.5.

NVIDIA released the powerful open-source MoE model Nemotron 3 Ultra with 550B parameters and a 1M context window, designed for long-running agent workloads, offering up to 5x performance improvement and 30% cost reduction. Meanwhile, Anthropic published research indicating early signs of Recursive Self-Improvement (RSI) in AI, revealing Claude now contributes over 80% of Anthropic's code.
