Researchers have developed AUGUstus, a novel Vision-Language-Action (VLA) model designed for autonomous driving that unifies action generation and understanding to overcome limitations of existing VLA systems. Unlike previous models that either degenerate into simpler Vision-Action systems or suffer from high latency due to autoregressive generation, AUGUstus employs a diffusion-based approach for action generation and an autoregressive method for Chain-of-Thought (CoT) understanding. This unified architecture allows for low-latency deployment while ensuring safer and more accurate trajectories by using CoT to supervise action generation during training. Experiments show AUGUstus achieves state-of-the-art performance on several benchmarks, including NAVSIMv1, NAVSIMv2, and nuScenes, with preliminary deployment on a real vehicle demonstrating its practical viability.
