Nvidia chief Jensen Huang has condemned US export controls designed to limit China’s access to artificial intelligence chips as “a failure” that spurred Chinese rivals to accelerate development of their own products.

NVIDIA also unveiled the first update to Isaac GR00T, its foundation AI model for humanoid robots, designed to help them learn and adapt in real time. The latest version, Isaac GR00T N1.5, includes GR00T-Dreams, a simulation tool that creates virtual training environments to accelerate robotic learning.
