NVIDIA announced that automakers BYD, Geely, Isuzu and Nissan will use its DRIVE Hyperion platform to develop level 4 autonomous vehicles, according to a company press release.

The chip maker said its platform provides a production-ready reference architecture that integrates compute, sensors, networking and safety systems for autonomous vehicle development. Level 4 vehicles can operate without human intervention in specific conditions.

NVIDIA (NASDAQ: NVDA) also announced an expanded partnership with Uber to launch autonomous vehicles powered by NVIDIA's full-stack software across 28 cities by 2028. The rollout will begin in Los Angeles and San Francisco in the first half of 2027.

Other mobility companies including Bolt, Grab and Lyft are using the DRIVE Hyperion platform for autonomous vehicle initiatives, the company said.

The company introduced NVIDIA Halos OS, which it described as a unified safety architecture for AI-driven vehicles built on ASIL D-certified foundations. The operating system includes safety middleware and applications designed to provide safety guardrails for autonomous systems.

NVIDIA also released Alpamayo 1.5, an updated version of its open AI model portfolio for autonomous vehicle development. The model takes driving video, vehicle motion history, navigation guidance and text prompts as inputs to generate driving trajectories with reasoning explanations.

The company said Alpamayo has been downloaded by more than 100,000 automotive developers since launching earlier this year. The platform includes simulation frameworks and datasets for building autonomous vehicle systems.

NVIDIA announced these developments at its GTC conference. The company also introduced NVIDIA Omniverse NuRec, a set of 3D simulation technologies that use real-world data to create interactive simulations for testing autonomous vehicle systems.
