Haven't seen much about the Nvidia Cosmos 3 video model that dropped, what's up with that?

Nvidia Cosmos 3 is an open physical AI foundation model built on a mixture-of-transformers architecture that combines vision reasoning, world generation, and action prediction for reasoning, simulation, and synthetic data generation. Unlike previous Cosmos releases with separate models for different capabilities, Cosmos 3 is a unified omni-model combining world generation, physical reasoning, and action generation built on a Mixture-of-Transformers architecture. Cosmos 3 Super and Nano variants are now available, with developers able to access models on Hugging Face and customize them using Hugging Face Diffusers and NVIDIA NIM microservices.
