NVIDIA Alpamayo

NVIDIA Alpamayo is a family of open vision-language-action models, simulation frameworks, and physical AI datasets for reasoning-based autonomous vehicle development. Its chain-of-thought models take multi-camera video and driving context as input and output both trajectories and reasoning traces that expose the logic behind each driving decision.
