  "text": "We’ve just released @nvidia #DRIVE Alpamayo-R1 (AR1) — the world’s first industry-scale open #reasoning #VLA model for autonomous-vehicle (AV) research. AR1 integrates Chain-of-Causation reasoning with trajectory planning to improve decision-making in complex driving scenarios.\n\nBuilt on @nvidia #Cosmos #Reason, AR1 is designed as a customizable foundation for a broad range of AV applications — from instantiating an end-to-end backbone for autonomous driving to powering advanced, reasoning-based auto-labeling tools.\n\nResources:\nModel: https://t.co/9nI9L08LJJ\nInference Code: https://t.co/QpPzLEsFnm\nPaper: https://t.co/8PSdQNDqwO\nBlog Post: https://t.co/S92N6ff58L\n\nA subset of the data used to train and evaluate AR1 is available in the @nvidia Physical AI Open Datasets: https://t.co/fD9eUcndya\n\nAR1 can be evaluated using AlpaSim (https://t.co/9Wqutgpe5d), @nvidia's newly released open-source AV simulation framework built specifically for research and development. (Separate post on AlpaSim coming soon.)\n\nThis release completes @nvidia’s trifecta — model, data, and simulator — to accelerate research and development in the autonomous-vehicle domain. Happy developing, and stay tuned for more!\n\nHuge thanks to the phenomenal team that made this possible @NVIDIAAI @nvidia.",
