• 🚗 AutoVLA integrates chain-of-thought (CoT) reasoning and physical action tokenization to directly generate planning trajectories through a unified autoregressive process, dynamically switching dual-thinking modes.
• ⚙️ Supervised fine-tuning (SFT) is employed to equip the model with dual thinking modes: fast thinking (trajectory-only) and slow thinking (enhanced with chain-of-thought reasoning).
• 🪜 Reinforcement fine-tuning (RFT) based on Group Relative Policy Optimization (GRPO) is adopted to further enhance planning performance and efficiency, reducing unnecessary reasoning in straightforward scenarios.
• 🔥 Extensive experiments across real-world and simulated datasets and benchmarks, including nuPlan, nuScenes, Waymo, and CARLA, demonstrate its competitive performance in both open-loop and closed-loop settings.

• 2025/09: AutoVLA is accepted by NeurIPS 2025 👏👏.
