Nvidia announces Groot N1, a foundation model for humanoid robotics

Nvidia is releasing what it’s calling an AI foundation model for humanoid robotics.

Announced at GTC 2025, the model, dubbed Groot N1, is a “generalist” model — trained on synthetic data and real data. Nvidia said that Groot N1 features a “dual system architecture” for “thinking fast and slow,” inspired by human cognitive processes.

Groot N1 an evolution of Nvidia’s Project Groot, which the company launched at GTC last year. Project Groot focused on industrial use cases, but Groot N1 broadens the focus to humanoid robots in a range of different sectors.

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 the ability to manipulate objects and execute multi-step sequences.

Groot N1 is available in open source, Nvidia said. Alongside the model, Nvidia is releasing simulation frameworks and blueprints for generating synthetic training data.
