Testing an anti-scheming training method on OpenAI models across 26 evaluations, Apollo Research and OpenAI found covert actions fell from 13% to 0.4% for o3, but the models’ reasoning often showed awareness of being evaluated, they report causal evidence that awareness reduced covert behaviour, and the authors could not exclude that the reduction was partly driven by it.
