A new research paper introduces a method for certifying the predictability horizon of equivariant world models. The approach provides a computable certificate that guarantees error bounds over time, stratified by the model's Lyapunov spectrum. This method proves that structure, specifically equivariance, is crucial for reliable long-term predictions, unlike scale alone. Empirically, an equivariant network on Lorenz-96 data accurately recovered the Lyapunov spectrum, while baselines failed. The certificate also successfully audited pre-trained models like TD-MPC2 and V-JEPA 2-AC, demonstrating its utility in assessing model calibration and trustworthiness. AI
