Nvidia is releasing what it’s calling an AI foundation model for humanoid robotics. Announced at GTC 2025 in San Jose, the model, dubbed Groot N1, is a “generalist” model, trained on both synthetic and real data. In a video introducing Groot N1, Nvidia says it features a “dual-system architecture” for “thinking fast and slow,” inspired by human cognitive processes. Groot N1 is an evolution of Nvidia’s Project Groot, which the company launched at its GTC conference last year. Project Groot was geared toward industrial use cases, but Groot N1 broadens the focus to humanoid robots in a range of different form factors. Groot N1’s slow-thinking system lets a robot perceive and reason about its environment and instructions, and then plan the right actions to take, according to Nvidia. As for the fast-thinking system, it translates the aforementioned plan into robotic actions, including actions that involve manipulating objects over multiple steps. Groot N1 is available in open source. Alongside the model, Nvidia is releasing simulation frameworks and blueprints for generating synthetic training data.
