On a challenging autonomous driving evaluation, adding meta-action and chain-of-thought reasoning data improved a VLA model’s trajectory prediction accuracy, reducing minimum average displacement error — the predicted path’s average deviation from the reference route — by 43%, from 2.08 to 1.18.

The global robotaxi market, physical AI’s first commercial breakthrough, is projected to reach $400 billion by 2035, with over 6 million commercial vehicles in operation as driverless fleets are already moving people through some of the world’s busiest and most complex streets.

Key facts

Summary

Meeting those demands requires enormous amounts of compute across the robotaxi development lifecycle, from preparing and training AI models to simulating and validating driving behavior, as well as real-time processing in the vehicle. NVIDIA provides an open platform for AI training, simulation and safety validation, with libraries, software development kits, workflows and models that developers can use alongside their own technology stacks. Every major robotaxi program operating at commercial scale today is running on NVIDIA’s modular stack, spanning AI training, simulation, in-vehicle computing, or a combination of the three, to develop and deploy fleets at scale.
