VLA-ULAP: Interleaving Cloud VLA Calls with Ultra-Lightweight Local Action Prediction at the Edge

The paper introduces VLA-ULAP, a lightweight local action predictor that interleaves remote vision–language–action (VLA) calls with on‑edge inference. ULAP, with only 7.4 M parameters, predicts action chunks in a single pass using current views, proprioception, and action history, eliminating the need for VLA hidden states or server round‑trips. Experiments on Jetson Orin Nano and simulated benchmarks show that VLA-ULAP can remove 48.8–76.7 % of VLA calls while preserving 95–97.5 % of baseline success, and it outperforms local VLA‑acceleration alternatives in both inference time and energy consumption.

Efficient Block-Layer Parallel Inference for Vision-Language-Action on Hybrid Architectures

arXiv:2608. 14586v1 Announce Type: cross Abstract: Vision-Language-Action (VLA) models are becoming a promising paradigm for autonomous driving, but their deployment on existing vehicle platforms remains difficult because they introduce both high inference latency and strong GPU-side resource pressure.

OxyGen: Unified KV Cache Management for VLA Inference under Multi-Task Parallelism

OxyGen introduces a unified KV cache management system for Vision‑Language‑Action (VLA) models that run multiple tasks in parallel, such as manipulation, conversation, and memory construction. By treating the KV cache as a shared resource, it eliminates redundant prefill operations and enables cross‑frame continuous batching, leading to significant speedups—up to 3.7× faster than isolated execution—while maintaining high language throughput and action frequency on both RTX 4090 and Jetson AGX Thor platforms. The approach is validated across several backbones and expert configurations, including deployment on a humanoid robot with on‑board Jetson hardware.

TurboVLA: Real-Time Vision-Language-Action Model at 32 Hz on an RTX 4090 with <1 GB VRAM

Vision-language-action (VLA) models commonly adopt an LLM-centric $V \to L \to A$ pathway, where visual observations are projected into the representation space of a large language model before being decoded into robot actions. Although effective, this design incurs substantial computation and memory overhead at every policy invocation.
