Summary

Nvidia announced Cosmos Reason 2 at CES 2026, the latest version of its vision-language model (VLM) designed for embodied reasoning in physical AI systems. Building on Cosmos Reason 1, which introduced a two-dimensional ontology for embodied reasoning and leads Hugging Face's physical reasoning for video leaderboard, Cosmos Reason 2 enhances reasoning capabilities for robots to navigate unpredictable physical environments and allows for enterprise customization. Nvidia also released an updated Cosmos Transfer model for generating robot training simulations. The company is expanding its open model ecosystem, including the Nemotron family, with new additions like Nemotron Speech for real-time, low-latency speech recognition (10x faster than competitors), Nemotron RAG for multimodal insights and strong multilingual performance with less compute, and Nemotron Safety for detecting sensitive data.

Key takeaway

For robotics engineers developing AI agents for physical environments, Cosmos Reason 2 offers enhanced embodied reasoning capabilities, enabling robots to plan actions and navigate complex physical spaces. You should explore Nvidia's expanded open model ecosystem, including Nemotron RAG for multimodal data agents and Nemotron Safety for PII detection, to build more robust and secure physical AI systems.
