NVIDIA releases Cosmos 3 open models for interactive world simulation

Cosmos 3 extends NVIDIA's world-foundation-model family toward interactive simulation, where agents act inside a generated environment and observe the consequences. This is key for training robots safely and at scale.

It echoes Yann LeCun's widely shared argument this week that real agents must predict the consequences of their actions rather than simply chase LLMs. Physical AI is also visible in the market: Xiaomi humanoids completing an 8-hour EV-parts shift drew 2,294 upvotes on r/singularity.

NVIDIA's open-model strategy, which also includes Nemotron 3.5 Transcribe trending number one on Hugging Face, drives demand for its hardware. Watch for robotics-lab adoption and sim-to-real results.
