Agentic AI systems capable of autonomous planning and extended environmental interaction pose a fundamental control problem: how can humans maintain meaningful oversight of systems that may exceed their own capabilities? Existing approaches to scalable oversight rely on complex assumptions, remain largely heuristic, or lack practical methods for sequential settings with statistical guarantees. We introduce Calibrated Collective Oversight (CCO), which aggregates diverse auxiliary scoring functions into a penalty measuring deviation from a conservative baseline. Inspired by Attainable Utility Preservation, CCO enables collective conservatism: actions face a penalty proportional to overseer concern, so high-utility actions are still selected when overseers find them unobjectionable and overridden only when concern accumulates. CCO calibrates this conservatism online using Conformal Decision Theory, ensuring that undesirable outcomes remain below a user-specified target threshold with finite-time bounds and no distributional assumptions. On a modified version of SWE-bench, weaker overseers successfully constrain an adversarially misaligned stronger agent; on MACHIAVELLI, CCO substantially reduces ethical violations while preserving reward. In both settings, empirical violation rates closely match the specified targets, as predicted by the theory.

Calibrating Conservatism for Scalable Oversight addresses the challenge of maintaining human control over advanced AI systems that may be more capable than their supervisors. As AI agents become more autonomous, they can pursue complex goals that might lead to unintended or harmful consequences. This paper introduces Calibrated Collective Oversight (CCO), a framework that allows weaker overseers—such as humans, smaller models, or heuristic critics—to constrain stronger agents by dynamically adjusting how much the agent is allowed to deviate from a safe, conservative baseline.

How the Approach Works

CCO functions by evaluating candidate actions through a collection of auxiliary overseers. These overseers do not need to be perfect; they simply provide scores on different dimensions like safety or adherence to rules. CCO aggregates these scores into a penalty that measures how much a proposed action deviates from a "baseline" action (a safe, default choice).
The system uses a "conservatism parameter" to balance the agent’s desire to maximize its own utility against the need to stay within safety bounds. If the agent’s actions are deemed risky, the system automatically increases this parameter to force the agent toward the safer baseline.

Online Calibration

A core innovation of CCO is its use of Conformal Decision Theory to manage this balance in real-time. After each action, the system observes whether a loss—such as an ethical violation or safety failure—has occurred. It then updates the conservatism parameter using a feedback loop: it increases caution after failures and relaxes it when the agent is performing safely. This ensures that the long-term rate of undesirable outcomes stays below a user-specified target, providing formal statistical guarantees without requiring assumptions about the environment.

Performance and Results

The researchers validated CCO in two distinct environments. In a modified version of SWE-bench, which involves autonomous software engineering tasks, CCO enabled weaker overseers to successfully constrain a stronger, adversarially misaligned agent. In the MACHIAVELLI benchmark, which tests agents in complex, multi-turn game scenarios, the framework significantly reduced ethical violations while maintaining the agent's ability to achieve its goals. In both cases, the actual rate of violations closely matched the targets set by the users, confirming that the theoretical guarantees hold in practice.

Key Considerations

CCO is designed specifically for sequential, agentic settings where actions have long-term consequences. Unlike previous methods that often rely on static rules or single-turn evaluations, CCO adapts to the reliability of the oversight ensemble as it encounters new states. By generalizing from specific reward functions to arbitrary scoring functions, the framework is flexible enough to incorporate a wide variety of safety signals, making it a practical tool for deploying safer, more controllable AI agents.
