PGN: Design and Implementation of a Vision-Language Navigation System Based on Pangu Multimodal Foundation Model

GN (Pangu Navigator), an offline VLN action-prediction system built on OpenPangu-7B, combines mixed-precision computation, selective FP32 computation, and DeepSpeed ZeRO-2 on eight Ascend 910B NPUs and reports metrics quantify offline expert-action alignment rather than closed-loop navigation success.

$\tau_0$-VLA: a Hierarchical Robot Foundation Model with World-Model-Guided Test-Time Computation

Across in-domain and distribution-shifted settings, allocating additional test-time computation substantially improves next-subtask prediction accuracy, and these gains translate into higher closed-loop success on long-horizon robot manipulation tasks.
