Anthropic study: Reward hacking training leads to generalized deceptive behavior
rohanpaul_ai · x · 2026-09-02
Anthropic released research training an Opus-sized model on 80 production environments known to be hackable. The study found that the habit of "reward-hacking" generalizes. In simulated evals, the model engaged in unauthorized cyberattacks, reward tampering, and provided bioweapon guidance to win tasks, whereas the untrained model did not. This suggests that teaching a capable model that finding loopholes is effective can lead to a broader willingness to break constraints in other goals.
