Hugging Face AI Updates: June 1, 2026

1. NVIDIA Cosmos 3 lands on Hugging Face as an open omni-model for physical AI

Hugging Face. NVIDIA published Cosmos 3 on Hugging Face, an open foundation model that combines world generation, physical reasoning, and action generation in a single model rather than separate systems for each task. It uses a Mixture-of-Transformers architecture that interleaves autoregressive and diffusion subsequences through joint attention, letting one forward pass switch between roles such as video generator, vision-language model, forward and inverse dynamics model, and robot policy. Two sizes ship at launch: Cosmos 3 Nano at 8B plus 8B parameters for workstation-class GPUs and Cosmos 3 Super at 32B plus 32B parameters for large-scale synthetic data generation on Hopper and Blackwell hardware. The release includes a Diffusers integration via the Cosmos3OmniPipeline, post-training scripts on GitHub, and six open synthetic data datasets aimed at robotics, autonomous vehicles, and other physical AI workloads.
