Nvidia's Cosmos Reason 2 boosts robot reasoning for complex tasks
Nvidia’s latest push into robotics lands on a familiar crossroads: turning the abstract power of large‑scale vision‑language models into something that can actually pick up a tool, sort a package or adjust to a shifting workspace. The company’s internal roadmap, which Briski says follows “th…,” signals a deliberate move from cloud‑bound inference to on‑board agents that must make split‑second judgments. Cosmos Reason 2, the newest iteration of the firm’s reasoning engine, is being positioned as the software glue that lets a robot move beyond pre‑programmed motions and respond to the messiness of real‑world environments.
While the hardware platform remains largely unchanged, the upgrade promises a deeper grasp of context, enabling machines to handle tasks that were previously out of reach for purely statistical models. In short, the upgrade aims to give robots a broader knowledge base and the ability to apply it when conditions shift unexpectedly.
These new robots combine broad fundamental knowledge with deep proficiency and complex tasks. She added that Cosmos Reason 2 “enhances the reasoning capabilities that robots need to navigate the unpredictable physical world.”
"These new robots combine broad fundamental knowledge with deep proficiency and complex tasks." She added that Cosmos Reason 2 "enhances the reasoning capabilities that robots need to navigate the unpredictable physical world." Moving to physical agents Briski noted that Nvidia's roadmap follows "the same pattern of assets across all of our open models." "In building specialized AI agents, a digital workforce, or the physical embodiment of AI in robots and autonomous vehicles, more than just the model is needed," Briski said. "First, the AI needs the compute resources to train, simulate the world around it. Data is the fuel for AI to learn and improve and we contribute to the world's largest collection of open and diverse datasets, going beyond just opening the weights of the models.
The open libraries and training scripts give developers the tools to purpose-build AI for their applications, and we publish blueprints and examples to help deploy AI as systems of models." The company now has open models specifically for physical AI in Cosmos, robotics, with the open-reasoning vision-language-action (VLA) model Gr00t and its Nemotron models for agentic AI. Nvidia is making the case that open models across different branches of AI form a shared enterprise ecosystem that feeds data, training, and reasoning to agents in both the digital and physical worlds. Additions to the Nemotron family Briski said Nvidia plans to continue expanding its open models, including its Nemotron family, beyond reasoning to include a new RAG and embeddings model to make information more readily available to agents.
The company released Nemotron 3, the latest version of its agentic reasoning models, in December. Nvidia announced three new additions to the Nemotron family: Nemotron Speech, Nemotron RAG and Nemotron Safety.
Will robots truly understand their surroundings? Nvidia's Cosmos Reason 2 claims to push reasoning VLMs from screen to steel. At CES 2026 the company unveiled a suite of models meant to move AI agents beyond chat, into the unpredictable physical world.
The CEO framed this as the start of an age of physical AI, while the product brochure promises broad fundamental knowledge paired with deep proficiency on complex tasks. Yet the announcement offers few metrics, and it remains unclear how the new reasoning layer will handle real‑time variability in unstructured environments. The statement that Cosmos Reason 2 “enhances the reasoning capabilities that robots need to navigate the unpredictable physical world” is plausible, but without benchmark data the claim is difficult to verify.
Nvidia continues to supply LLMs for software, positioning itself as a provider for fully AI‑powered systems, but the roadmap’s exact milestones are still vague. A step forward. In short, the hardware and model upgrades are evident, but whether they translate into reliable, autonomous performance in everyday settings is uncertain.

Common Questions Answered
What is the primary purpose of Nvidia's Cosmos Reason 2 as described in the article?
Cosmos Reason 2 is designed to enhance robot reasoning for complex, real‑world tasks, translating large‑scale vision‑language model capabilities into on‑board agents that can pick up tools, sort packages, and adapt to shifting workspaces. By moving inference from the cloud to the robot itself, it enables split‑second judgments in unpredictable environments.
How does Cosmos Reason 2 differ from Nvidia’s previous AI roadmap according to Briski’s comments?
Briski notes that the new roadmap shifts focus from cloud‑bound inference to physical embodiment, emphasizing “the same pattern of assets across all of our open models” but applied to specialized AI agents, digital workforces, and autonomous vehicles. This marks a deliberate move toward on‑board reasoning engines that operate directly within robots.
At which event was Cosmos Reason 2 unveiled, and what significance does the article attribute to that timing?
Nvidia unveiled Cosmos Reason 2 at CES 2026, positioning it as the launch of an “age of physical AI.” The article highlights the timing as a signal that Nvidia is pushing vision‑language models from screen‑based chat applications into steel‑bound robots and autonomous systems.
What claims does Nvidia make about the capabilities of Cosmos Reason 2, and what caveats does the article mention?
Nvidia claims that Cosmos Reason 2 provides broad fundamental knowledge combined with deep proficiency on complex tasks, allowing robots to navigate unpredictable physical worlds. However, the article points out that the announcement provides few concrete metrics, leaving the actual performance of the system unclear.
