Expensive Requirements of Current VLAs
Current Vision-Language-Action (VLA) models for autonomous driving face significant challenges due to their reliance on massive dataset collection and dense reasoning annotations. This leads to high costs in data curation, annotation, training, and inference. NORD addresses these limitations by being reasoning-free and data-efficient.

NORD's Data-Efficient Training Pipeline
NORD employs a novel two-stage training pipeline. It starts with supervised fine-tuning (SFT) on a small driving dataset, leading to a weak SFT policy. Crucially, it then uses Dr. GRPO for reinforcement learning post-training to effectively optimize this weak policy and achieve competitive performance without requiring reasoning annotations.

Competitive Performance without Reasoning
Addressing Difficulty Bias in GRPO
The authors identified that standard GRPO struggles to optimize weak SFT policies when applied to small, reasoning-free datasets due to a 'difficulty bias.' This bias disproportionately penalizes reward signals from scenarios that produce high-variance rollouts, which are prevalent in intermediate-mean performance cases for weak SFT models.

Competitive Performance on Benchmarks
NORD demonstrates that high-performance autonomous driving VLAs do not necessarily require large datasets or reasoning, paving the way for more accessible and scalable models. It achieves competitive RFS on WaymoE2E and surpasses AutoVLA-BON on NAVSIM's PDM score, all while being significantly more data and token efficient.
NORD's Edge on WaymoE2E and NAVSIM
NORD achieves performance competitive with state-of-the-art models on challenging driving benchmarks like WaymoE2E and NAVSIM. This is achieved with at least 60% less data than reasoning-based VLAs and without any reasoning annotations. On WaymoE2E, NORD ranks among the top performing VLAs, and on NAVSIM, NORD-BoN surpasses reasoning-based AutoVLA-BON.
