AI Safety: Rethinking Protection Layers

AI safety efforts often focus on aligning the model’s internal behavior, but this approach may be insufficient. Instead of relying on AI’s “good intentions,” real-world engineering practices suggest implementing hard boundaries at the execution level, such as OS permissions and cryptographic keys. By allowing AI models to propose any idea, but requiring irreversible actions to pass through a separate authority layer, unsafe outcomes can be prevented by design. This raises questions about the effectiveness of action-level gating and whether safety investments should prioritize architectural constraints over training and alignment. Understanding and implementing robust safety measures is crucial as AI systems become increasingly complex and integrated into society.

The focus of AI safety has traditionally been on aligning the internal behavior of AI models, ensuring they are honest and imbued with better values. However, this perspective may overlook a crucial aspect of engineering safety: the importance of implementing hard boundaries at the level of execution. In engineering practices, safety is often ensured by setting strict limits on what actions can be taken, rather than relying solely on the intentions or internal processes of a system. This suggests a shift in AI safety strategies might be necessary, from trying to make AI models inherently safe to designing systems where unsafe outcomes are structurally unreachable.

By allowing AI models to propose any action, including those that might be wrong or adversarial, and then filtering these actions through a separate authority layer, the risk of harmful outcomes can be minimized. This layer would act as a gatekeeper, deterministically blocking any irreversible actions such as financial transactions, access to sensitive information, or mass communication, unless they meet predefined safety criteria. This approach emphasizes the importance of constraining actions rather than attempting to control the model’s imagination or thought processes, which can be more unpredictable and difficult to manage effectively.

However, there are significant questions about the feasibility and effectiveness of action-level gating. One concern is whether indirect harms, such as those arising from persuasion or coordination, could bypass these constraints. As AI systems become more complex, maintaining a small, trusted boundary that remains non-bypassable could prove challenging. This raises the issue of whether safety investments should shift focus from training and alignment toward developing robust architectural constraints that can adapt to increasing system complexity.

This perspective matters because it challenges the current paradigm of AI safety and proposes a potentially more effective way to mitigate risks associated with advanced AI systems. By focusing on architectural constraints rather than solely on model alignment, we may be able to create safer AI systems that can operate within defined boundaries, reducing the likelihood of unintended and potentially harmful actions. As AI continues to evolve and integrate into various aspects of society, ensuring the safety and reliability of these systems is paramount, making this discussion highly relevant for the future of AI development and deployment.
