NVIDIA unveils GR00T 2 world-action model and Isaac Lab 3.0 at CoRL

NVIDIA introduced GR00T 2, an open world-action model for robots, and Isaac Lab 3.0, a faster open-source simulation framework, at the CoRL conference on November 9, 2026.

NVIDIA announced GR00T 2, an open frontier world-action model for robots, alongside Isaac Lab 3.0, an open-source robot-learning framework, on November 9, 2026 at the CoRL robotics conference in Austin, Texas, according to NVIDIA's CoRL announcement.

What's new in GR00T 2 and Isaac Lab 3.0

GR00T 2 is an open frontier world-action model built on NVIDIA Cosmos, trained on diverse robot and human data, including 100,000 hours of NVIDIA's open-source human egocentric data.
With zero task-specific demonstrations, GR00T 2 completed 40 of 50 evaluated tasks at least once.
With one demonstration per task, GR00T 2 averaged 71% success across 50 tasks; with five demonstrations, success rose to 95%.
GR00T 2 ranks in the top 3 on the RoboCasa365, RoboLab, RoboDojo and MolmoSpaces benchmarks.
Isaac Lab 3.0 integrates NVIDIA PhysX and the open-source Newton physics engine, modeling cables, cloth and articulated systems such as robotic hands.
Isaac Lab 3.0 adds a reinforcement post-training library and agent-driven environment setup, delivering up to 2.5x training throughput over Isaac Lab 2.3 on a vision-based dexterous-manipulation benchmark.

What it means for robot builders

Pairing an open world-action model with a faster, open-source simulation framework lowers the bar for teams building and training robot-control agents outside NVIDIA's own labs. Developers can test GR00T 2's few-shot learning, which reached 71% success with one demonstration per task and 95% with five, against their own tasks, while Isaac Lab 3.0's higher training throughput and new physics engine let them simulate more complex manipulation, from cloth handling to dexterous hands, before moving to real hardware.

Early partners and users

Partners using GR00T 2 include Nexuni, Foxconn, Siemens and MicroAGI.
Isaac Lab 3.0 users include Skild AI, Flexion, FieldAI, Dyna Robotics, Walden Robotics, Dexmate, UT Austin and the University of Washington.
