VeriVLA: Adaptive Test-Time Verification for Flow-Based VLAs with Latent World Models

arXiv 2026 23.4 method

TLDR

VeriVLA uses a training-free trigger and JEPA-based latent world model to adaptively verify and rank action chunks from flow-based VLAs, improving real-world and simulated manipulation.

Reasoning

The paper is strong in combining a lightweight trigger with a latent world model for efficient test-time verification, and it provides real-world and simulation results. A weakness is that the abstract provides limited detail on baseline comparisons, limitations, and generality beyond three manipulation tasks.
