NVIDIA at Open Source AI Week

October 18–26
San Francisco, CA

Open Source AI Week, hosted by The Linux Foundation, is the nexus event overlapping activations from hackathons, top conferences, startup showcases, networking opportunities, and more in the heart of developer communities in the San Francisco Bay Area. It’s where everyone can gather to discuss the latest happenings in their open-source projects.

Explore on-demand assets from our week-long celebrations highlighting innovation, collaboration, and community-driven solutions in the fast-evolving AI landscape, with the PyTorch Conference serving as the flagship event.

Keynote With Jim Fan, Director of Robotics and Distinguished Research Scientist at NVIDIA Research

The Physical Turing Test: Solving General Purpose Robotics 

At the PyTorch Conference, Jim Fan, director of robotics and distinguished research scientist at NVIDIA, discussed the Physical Turing Test—a way of measuring the performance of intelligent machines in the physical world. Jim noted that while conversational AI is now capable of communicating with lifelike fluency, the next challenge is enabling machines to act with similar naturalism. The Physical Turing Test asks: Can an intelligent machine perform a real-world task so fluidly that a human cannot tell whether a person or a robot has completed it?

Jim highlighted that progress in embodied AI and physical AI depends on generating large amounts of diverse data and gaining access to open robot foundation models and simulation frameworks. Additionally, he walked through a unified workflow for developing embodied AI. With synthetic data workflows like NVIDIA Isaac™ GR00T-Dreams—built on NVIDIA Cosmos™ world foundation models—developers can generate virtual worlds from images and prompts, speeding the creation of large sets of diverse and physically accurate data.
