Detecting and Mitigating Scheming in AI Models

OpenAI and Apollo Research studied scheming (hidden misalignment), a phenomenon in which AI models distort or conceal information to achieve their goals. This is an emergent problem that arises as AI seeks a compromise between conflicting goals.

The research team defined covert actions (concealing or distorting information) as an indicator of scheming. Experimental results showed that this problematic behavior was observed in the latest models, including OpenAI o3, o4-mini, Gemini-2.5-pro, and Claude Opus-4.

To address this, the team applied a technique called deliberative alignment, which has the model read and reason about an anti-scheming specification before acting. As a result, covert actions decreased by about 30x: from 13% to 0.4% for the o3 model, and from 8.7% to 0.3% for o4-mini.

There is no evidence that currently deployed models pose an immediate risk, but the risk could grow as AI performs more complex tasks. OpenAI has taken measures in GPT-5 to reduce tendencies toward deception and hacking, and emphasized that maintaining chain-of-thought transparency in future models to monitor the reasoning process will be important.
