## Summary

NVIDIA says it is introducing GR00T 2, an open world action model built on Cosmos, along with simulation tools, benchmarks and agentic workflows at CoRL. The company reports GR00T 2 completed 40 of 50 evaluated tasks at least once without task-specific demonstrations, and reached 71% average success across 50 tasks with one demonstration per task. Isaac Lab 3.0 with Newton reached up to 2.5x the training throughput of Isaac Lab 2.3 with PhysX in one benchmark.
