NVIDIA Unleashes Personal and Physical AI with RTX Spark and Cosmos 3

In a groundbreaking series of announcements at Computex 2026, NVIDIA has once again pushed the boundaries of artificial intelligence, unveiling two pivotal technologies: RTX Spark and Cosmos 3. These innovations are poised to redefine personal computing with powerful on-device AI agents and accelerate the development of physical AI, promising a future where our digital and physical worlds are seamlessly integrated with intelligent systems.

RTX Spark: The Dawn of Personal AI PCs

NVIDIA RTX Spark™ is a new superchip designed to reinvent Windows PCs for the era of personal AI agents. This powerful chip boasts an impressive 1 petaflop of AI performance and up to 128GB of unified memory, making it the world’s first Windows PC purpose-built for running sophisticated AI agents locally. This means that complex AI tasks, which previously required cloud processing, can now be executed directly on your personal computer, offering unprecedented speed, privacy, and security.

The collaboration between NVIDIA and Microsoft is central to this vision. They are working together to deliver a native Windows experience for personal agents, incorporating new security primitives and NVIDIA OpenShell. OpenShell provides a robust runtime environment that ensures agents operate safely and under full user control, allowing for intelligent routing of queries to local models based on privacy policies and even disguising personal information when interacting with cloud models. This robust security layer is already being adopted by leading agent developers like Hermes Agent and OpenClaw, paving the way for a new class of Windows applications that can execute tasks across various applications, reason through workflows, generate media, and semantically search local files.

Jensen Huang, NVIDIA’s CEO, highlighted the transformative potential: “The PC is being reinvented. With RTX Spark and Microsoft Windows, you ask — and the PC does the work. RTX Spark brings everything NVIDIA has built — CUDA, RTX, our AI platform — into a single superchip. Local agents. Frontier models. Creative workflows. RTX games. All on a laptop. This is the new PC. The personal AI computer.”

Cosmos 3: Advancing Physical AI and World Models

Beyond personal computing, NVIDIA also introduced Cosmos 3, an open world foundation model for physical AI. Built on a breakthrough mixture-of-transformers architecture, Cosmos 3 combines vision reasoning, world generation, and action prediction into a single, cohesive system. This omnimodel can natively understand and generate text, images, video, ambient sound, and actions with leading physics accuracy, drastically reducing physical AI training and evaluation cycles from months to days.

Cosmos 3 addresses a critical challenge in physical AI: enabling robots, autonomous vehicles, and vision agents to generalize effectively in the real world with limited training data. By providing a powerful pretrained foundation, developers can build physical AI systems with less data and lower training costs. NVIDIA has also launched the NVIDIA Cosmos Coalition, a global collaboration with leading AI labs and robotics leaders, to advance next-generation open world models.

The Future is Now

The dual launch of RTX Spark and Cosmos 3 signifies a major leap forward in the AI landscape. RTX Spark empowers individuals with powerful, private AI capabilities directly on their devices, transforming the PC from a mere tool into an intelligent teammate. Meanwhile, Cosmos 3 accelerates the development of physical AI, paving the way for more intelligent robots, safer autonomous vehicles, and advanced vision AI systems that can perceive, reason, plan, and act in the physical world. These innovations collectively paint a picture of a future where AI is not just a distant concept but an integral, intelligent part of our daily lives, both digital and physical.
