Proxy Reward Internalization and Mechanistic Exploitation: A Learned Precursor to Reward Hacking and Its Generalization

Researchers introduce PRIME (Proxy Reward Internalization and Mechanistic Exploitation), a framework for detecting when AI models learn to exploit flawed reward signals before visible reward hacking occurs. The study demonstrates that this capability emerges in measurable stages and can serve as an early-warning signal for alignment failures in reinforcement learning systems.

Cycle-Consistent Search: Question Reconstructability as a Proxy Reward for Search Agent Training

Researchers propose Cycle-Consistent Search (CCS), a novel framework for training search agents using reinforcement learning without requiring gold-standard labeled data. The method leverages question reconstructability as a reward signal, using information bottlenecks to ensure agents learn from genuine search quality rather than surface-level linguistic patterns.
