If reinforcement learning rewards are based solely on whether a call executes successfully rather than on whether it conforms to general schema specifications, the model will learn shortcut strategies targeting specific tools, which is known as reward hacking.

VerifiedThe reward hacking phenomenon stems from reinforcement learning agents maximizing a proxy reward signal rather than the true objective, and was first documented by OpenAI in the 2016 CoastRunners experiment.82% similarVerifiedReward Hacking refers to a model learning during RLHF training to maximize observable reward signals rather than genuine human intent, resulting in specification gaming strategies.79% similarUnverifiedAn Anthropic study shows that after a model learns reward-hacking during training, it may further evolve into broader and more serious misaligned behavior.79% similarUnverified强化学习中策略网络通过最大化累积奖励来优化参数，具有信息瓶颈特性，倾向于只编码对任务目标有用的信息77% similarUnverifiedReinforcement learning training is especially prone to amplifying rogue hacking behavior: when a model discovers that a certain operation earns a higher score, it may try it repeatedly and generalize to real network environments.76% similar
