NVIDIA GTC 2026 unveils open physical AI stack

NVIDIA is turning physical AI into a platform, not just a pile of models, which is the more important story here. The moat is the workflow and data flywheel, because robotics teams usually lose time on integration and dataset quality long before they hit model limits.

• –Cosmos Curator and Evaluator close the loop on data quality, synthetic generation, and scoring.
• –OSMO is the sleeper hit because YAML orchestration across cloud, simulation, and edge is the glue robotics teams actually need.
• –Isaac GR00T N1.6 keeps NVIDIA at the center of humanoid VLA work, and the GitHub release suggests real developer-facing intent.
• –Kimodo and SOMA-X extend the stack into motion authoring and body-model standardization for sim, teleop, and synthetic data.
• –The official release also includes Cosmos Transfer and Cosmos Reason, so this Reddit list is useful but not exhaustive.
