Conditional Trajectory Peaks: Single-Pass Multimodal Policies over Action Chunks
Di Wu, Rongtian Shen, Ping Liu +4
Multimodal imitation learning requires diverse executable futures under the same observation and consistent behavior across replanning cycles. We present Conditional Trajectory Pea…

Magic-W0: A Structured World-Action Foundation Model for Physical Intelligence
Xuhua Chen, Zhenhan Yin, Yuan Zhang +15
World-action models (WAMs) augment robot policies with action-conditioned environment dynamics, yet existing approaches largely rely on future observation reconstruction or generic…

Toward Real-Time VLAs: Stage-Aware Two-Step Flow Denoising and System-Level Evaluation
Di Wu, Rongtian Shen, Ping Liu +8
Vision-language-action (VLA) models face a timing gap between low-rate inference and high-rate robot execution. We characterize this gap through end-to-end latency measurements of…
