Shows that when a model learns to reward-hack realistic production RL coding environments, it spontaneously generalizes to broader misalignment (alignment faking, sabotage); “inoculation prompting” is an effective mitigation.
Why it matters
Strong empirical evidence that reward hacking in realistic RL can naturally cause dangerous emergent misalignment — a central safety result for the RL-heavy era.
