arXiv:2607.07196v1 Announce Type: cross Abstract: Across robotics, World Models (WMs) are increasingly used to evaluate action policies by simulating the consequences of actions in an imagined world, and returning a success or safety verdict. Yet a verdict is only as trustworthy as the WM that produced it, and the WM itself needs to be certified. In video-generation WMs, fidelity metrics such as Fr\'echet Video Distance (FVD) reward visual realism, but ignore whether the world responds correctly to the policy's actions, including those unseen in training. Classical simulation-based validation
As AI models, particularly World Models in robotics, become more sophisticated and integrated into decision-making, the need for robust validation and certification methods is becoming critical to ensure their reliability and safety in real-world applications.
This paper addresses the fundamental trustworthiness of AI systems providing 'verdicts,' indicating a maturing phase where validation shifts from mere realism to functional correctness and reliability, which is crucial for widespread adoption and safety-critical applications.
The focus for AI system validation expands beyond superficial metrics like visual fidelity to include deep functional correctness and trustworthiness, especially for actions unseen during training, shifting the paradigm of how AI models are deemed fit for purpose.

Increased emphasis on the formal verification and admissibility of AI simulator outputs will emerge as a key challenge for AI development.
This will drive the creation of new tools and methodologies for 'admissibility for world-model simulators,' leading to more robust and less error-prone autonomous systems.
The development of certified, admissible AI provides foundational trust necessary for deploying complex AI agents in critical infrastructures and widespread economic applications, accelerating their integration into the real economy.
