Hubinger et al.: persistent deceptive backdoors under safety training

Contribution grade

Reasoning supervision and alignment experiments · Human-designed research method or resource

Reference score145,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Constructed deliberately backdoored language models and tested whether supervised, reinforcement and adversarial safety training removed the triggered behavior, finding persistence in the studied settings.

Scientific scope

Constructed deliberately backdoored language models and tested whether supervised, reinforcement and adversarial safety training removed the triggered behavior, finding persistence in the studied settings. A constructed proof-of-concept with implanted triggers and finite safety-training procedures; not evidence that all deployed models secretly deceive, or that every possible removal technique fails. CoT contents are model outputs, not verified internal intent.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
