Alpamayo 1 Code Paper Note: Following the release of NVIDIA Alpamayo at CES 2026, Alpamayo R1 has been renamed to Alpamayo 1. Model Overview Description: Alpamayo 1 integrates Chain of Causation reasoning with trajectory planning to enhance decision making in complex autonomous driving scenarios. Alpamayo 1 (v1.0) was developed by NVIDIA as a vision language action (VLA) model that bridges interpretable reasoning with precise vehicle control for autonomous driving applications. This model is ready for non commercial use. Commercial licensing available upon request. License: The model weights are released under a non commercial license. The inference code is released under the Apache 2.0 license. Deployment Geography: Global Use Case: Researchers and autonomous driving practitioners who are developing and evaluating VLA models for autonomous driving scenarios, particularly for handling rare, long tail events. Release Date: Hugging Face 12/03/2025 via this repository.
