The Power of Linear Attention
LADY introduces the first fully linear attention-based generative model for end-to-end autonomous driving, directly addressing the quadratic computational cost of traditional Transformers. By employing lightweight RNN-style RWKV-7 modules and a novel Linear Cross-Attention (LICA) mechanism, LADY ensures constant computational and memory overhead, regardless of historical data length. This is crucial for integrating long-range temporal context, which is vital for robust decision-making in dynamic autonomous driving scenarios.
Key strengths include: Constant-time inference, efficient cross-modal fusion (camera/LiDAR), and support for multi-modal trajectory generation through a diffusion-based decoder, allowing for diverse and safe driving behaviors.
Unprecedented Efficiency & Accuracy
Experiments on NAVSIM and Bench2Drive benchmarks reveal LADY's superior performance. The model not only achieves state-of-the-art planning accuracy (PDMS score 90.9) but also dramatically reduces computational costs. Inference time and memory usage remain virtually constant as the input frame count increases, unlike Transformer-based models whose costs rise sharply.
Specifically, LADY demonstrates up to 30.6x faster inference time and 18.1x lower memory usage compared to Transformer baselines (e.g., DiffusionDrive), making it ideal for real-time operations on resource-limited edge devices. This efficiency does not compromise safety or comfort, as evidenced by high scores across all key metrics.
Practicality for Real-World Deployment
LADY's design directly tackles the deployment challenges of autonomous driving. Its constant-time and memory profile ensures predictable performance, essential for safety-critical systems. The ability to integrate multi-frame historical sensor information without increased overhead allows for a more comprehensive understanding of dynamic environments, predicting occluded hazards and complex agent interactions with greater accuracy.
Validation on edge devices like NVIDIA Jetson AGX Orin confirms its practicality, proving LADY can deliver robust, real-time autonomous driving capabilities where traditional Transformer models would fail due to computational constraints. This opens doors for widespread adoption in various autonomous applications.

| Cross-Modal Fusion | Lightweight LICA Mechanism – efficient fusion of camera/LiDAR | Conventional Softmax Attention – higher overhead for multimodal tasks |
Case Study: Enhancing Fleet Autonomy with LADY
A leading logistics enterprise sought to upgrade its autonomous delivery fleet for urban environments. Their existing system, reliant on Transformer-based planning, struggled with real-time performance in complex intersections and required costly high-end GPUs for each vehicle, limiting scalability.
By integrating LADY, the enterprise achieved a breakthrough. LADY's constant-time inference allowed vehicles to make faster, more accurate decisions, drastically reducing delays in dynamic traffic. The linear memory footprint enabled the use of more affordable edge-AI hardware, cutting per-vehicle deployment costs by over 40%. Furthermore, LADY's ability to efficiently process long-range temporal data led to a 15% reduction in planning errors, improving safety and driver comfort scores. The fleet now navigates urban landscapes with unprecedented efficiency and reliability, demonstrating a significant competitive advantage.
