Summary

This live stream from NVIDIA’s Cosmos Labs series focuses on building reasoning agents for physical AI using Cosmos Reason. The session features multiple presenters: Sharon and Tingu from Inbot discuss social reasoning for humanoid robots, demonstrating how Cosmos Reason can infer human intent, assess physical risk, handle multi-person interactions, and understand social contact. They show examples from egocentric camera views and compare Cosmos Reason with other models. Sammy then presents the Video Search and Summarization (VSS) blueprint, an open-source reference architecture that combines vision language models, computer vision, and large language models to extract insights from videos, generate summaries, and answer questions. The session includes a walkthrough of the VSS UI and REST APIs, with details on deployment options and scalability. Finally, Shun discusses fine-tuning Cosmos Reason for traffic understanding, showing how domain-specific data improves performance in complex environments. The stream concludes with Q&A and community engagement.
