📦 Architecture
🧠 Data & Training
🚀 Performance
Architecture: The Cosmos-Reason Backbone
Alpamayo-R1 (AR1) leverages the Cosmos-Reason VLM backbone, specifically designed for Physical AI applications and pre-trained on 3.7M Visual Question Answering (VQA) samples. This foundation provides strong physical common sense and embodied reasoning. Key innovations include efficient multi-camera tokenization, a diffusion-based trajectory decoder, and a multi-stage training strategy (SFT + RL) for reasoning and action consistency. The modular design allows integration of off-the-shelf VLMs while maintaining domain-specific efficiencies for real-time control. For instance, multi-camera video tokenizers like Flex can achieve up to 20x token compression.
Data & Training: Chain of Causation (CoC)
The Chain of Causation (CoC) dataset is central to AR1, built via a hybrid auto-labeling and human-in-the-loop pipeline. CoC provides decision-grounded, causally linked reasoning traces aligned with driving behaviors, addressing limitations of prior free-form reasoning datasets. Our multi-stage training strategy involves supervised fine-tuning (SFT) on CoC data to elicit reasoning, followed by reinforcement learning (RL) to optimize reasoning quality and enforce reasoning-action consistency. RL post-training is critical for refining the model's ability to generate grounded and logically consistent reasoning, showing 45% improvement in reasoning quality compared to SFT alone.
Performance: Open-Loop & Closed-Loop Metrics
AR1 demonstrates significant performance gains. In open-loop trajectory prediction, AR1 achieves up to a 12% improvement in planning accuracy on challenging cases compared to a trajectory-only baseline. In closed-loop simulation using AlpaSim, AR1 shows a 35% reduction in off-road rate and a 25% reduction in close encounter rate. Model scaling from 0.5B to 7B parameters consistently improves performance, with the 7B model achieving an 11% reduction in minADE6. On-vehicle road tests confirm real-time performance (99 ms latency) and successful urban deployment, validating its practical path towards Level 4 autonomous driving.
