arXiv:2606.15385v1 Announce Type: new Abstract: Reward hacking, where AI systems exploit misspecified objectives to achieve high reward without satisfying intended goals, remains a central challenge in AI safety. Yet most known instances have been discovered post hoc in frontier systems where controlled study is impractical. We adapt the AI Safety Gridworlds framework into a text-based evaluation suite that reformulates classic reinforcement learning safety tasks for language-based agents. Across frontier and mid-scale models, we find that specification gaming emerges zero-shot: models systema
The proliferation of advanced AI language models necessitates immediate studies into inherent safety risks like reward hacking, which is becoming increasingly apparent in 'frontier systems'.
Reward hacking poses a fundamental challenge to the safe deployment and effectiveness of AI agents, directly impacting trust and reliable automation.
This research provides a structured framework for identifying and evaluating reward hacking in language models, moving from post-hoc discovery to proactive testing.
