Isaac GR00T N1

NVIDIA's first open foundation model for humanoids, released at GTC in March 2025. It splits the job in two: a slower vision-language part reads the scene and the instruction and plans, and a fast action part turns that plan into smooth joint movements. Robot makers download it and fine-tune it on their own real or simulated data. The published checkpoint is about 2 billion parameters (GR00T-N1-2B).
