## 核心内容

针对物理AI任务中自回归视觉语言模型逐token生成空间规划效率低的问题，研究提出VFlash方法。该方法利用视觉原语结构特性，通过轻量级drafter单次前向传播联合预测完整原语坐标，支持变长轨迹与紧凑框。实测显示其在3D点运动预测任务中生成速度较自回归解码提升约25倍，且在2D/3D机器人轨迹任务中预测误差持续降低。

VFlash训练直接基于标注原语，无需复现目标token序列即可接受结构有效预测，解耦了空间精度与文本对齐约束。在世界动作模型验证中，以VFlash规划为条件的系统在MolmoSpaces四个任务套件上取得70.2%平均成功率，显著优于基线模型的62.6%。该架构适配不同原语类型与维度，为高频实时机器人控制提供了高效视觉规划后端方案。

## 英文摘要 (Abstract)

Models for physical AI tasks, such as robotics and autonomous driving, need not reason solely in language. They can use visual plans--points, bounding boxes, and trajectories--to represent spatial goals and anticipate motion. However, autoregressive vision-language models generate these plans one coordinate token at a time, making richer predictions increasingly costly. We introduce VFlash, a method for fast, accurate visual planning through Flash Primitive Decoding. VFlash exploits the known structure of visual primitives to predict their coordinates jointly, using a lightweight drafter that generates an entire primitive in one forward pass. The layout adapts to the primitive's type, dimensionality, and length, supporting compact boxes and long, variable-length trajectories. Crucially, spatial accuracy need not require reproducing an autoregressive model's exact token sequence. VFlash therefore trains on annotated primitives and directly accepts structurally valid predictions without target-token agreement. Across the evaluated 2D and 3D robot trajectory tasks, VFlash consistently reduces prediction errors relative to autoregressive decoding. Preliminary single-rollout measurements indicate approximately 25x faster generation for 3D point motion forecasting. A world action model conditioned on VFlash plans achieves 70.2% average success across four MolmoSpaces task suites, compared with 62.6% for the baseline.
