The rapid evolution of computational materials engineering has ushered in an era where data-driven approaches increasingly dominate discovery pipelines, leveraging vast datasets and expansive model architectures to uncover material properties and behaviors. This conceptual analysis examines the phenomenon of model expansion in materials informatics, focusing on scaling laws that emerge independently of traditional physics-based derivations. By dissecting the interplay between dataset scaling, parameter proliferation, and computational resource demands, we highlight how such expansions influence epistemic gains in materials discovery. A core gap in current paradigms lies in the overreliance on empirical scaling metrics, which often overlook the nuanced trade-offs between model complexity and interpretive insight. To address this, we introduce the "Insight Amplification Cascade" framework, a layered conceptual structure that maps data infrastructures to inference dynamics, emphasizing feedback mechanisms that balance energy costs against discovery yields. This framework integrates representation learning with uncertainty quantification to steer computational workflows toward sustainable scaling. Implications extend to autonomous discovery systems, where model expansion fosters robust inverse design without necessitating physics-grounded priors. Ultimately, this analysis underscores the need for infrastructure-level reforms in materials AI, promoting scalable yet interpretable ecosystems that enhance long-term innovation in computational materials engineering. Through this lens, we advocate for a reevaluation of scaling strategies to prioritize epistemic efficiency over mere parametric growth.
