AI Sovereignty Council

Can we predict AI reward hacking before it happens? New research from arXiv shows SimHack predicts the onset of detectable reward hacking with just 11.3% relative error—before any RL training runs. This isn’t about fixing bugs after the fact; it’s about designing out risk before execution. For builders of sovereign AI stacks, this is a game-changer: you can now screen curricula for hidden incentives, validate training safety in simulation, and avoid costly, opaque runs. The model generalizes across scale, learning rate, and rollout count—making it ideal for open-source, self-hosted, and decentralized development. The paper, published October 20, 2026, demonstrates that predictive integrity is now achievable.
