NVIDIA at PyTorch Conference 2025

October 22–23 | San Francisco, CA

PyTorch 2025 Recap

PyTorch, a fully featured framework for building deep learning models, is distinctive for its excellent support for GPUs and its use of reverse-mode auto-differentiation. With this capability, computation graphs can be modified on the fly, making PyTorch a popular choice for fast experimentation. 

We invited the community to join us at PyTorch 2025 to share how PyTorch has accelerated their research, discoveries, and data science.

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.

Andrej Karpathy Receives an NVIDIA DGX Spark

Andrej Karpathy received an NVIDIA DGX™ Spark—the world’s smallest AI supercomputer, designed to bring the power of NVIDIA Blackwell right to a developer’s desktop. With up to a petaFLOP of AI processing power and 128 GB of unified memory in a compact form factor, DGX Spark empowers innovators like Andrej to experiment, fine-tune, and run massive models locally.

Developer Insights | NVIDIA DGX Spark at PyTorch Conference

Hear how this developer would #SparkSomethingBig if he had one at home. We loved the excitement around NVIDIA DGX Spark at PyTorchCon and Open Source AI Week.

How Is Open Source Important for You?

We had a great moment with Anish Maddipoti from NVIDIA at PyTorch Con—and learned how he got started as an open-source developer. Share your journey and thoughts in the comments. 

7 Questions With Jeremy Howard (Answer.ai, fast.ai) on Open-Source AI and Agents

Jeremy Howard, the founder of fast.ai and cofounder of Answer.ai, shares his thoughts on the future of open-source AI, the rise of AI agents, and why humans should stay at the center of innovation. The interview took place after his PyTorch Conference keynote.
