GPT-5.6 won’t be Oppenheimer

TLDR We created a scenario where frontier models discover dangerous scientific findings. Models were asked to create a report on a group of findings, where one is dual-use. We observe that: GPT-5.6 does not mention the dangerous finding in most (93%) of its reports, when told that the reports leak to the military. GPT-5.6 deletes the result and does not report the finding in 57% of the episodes. In contrast, Astra, Opus 5.5 and Fable 5.1 rarely delete the finding . Furthermore, in cases where these models do delete the finding, they always report so. Introduction In 1933, Szilard worked out that a chain reaction was possible, and filed a secret patent the next year to keep it out of circulation. On the other hand, Robert Oppenheimer led the building of the atomic bomb. He spent the rest of his life struggling with what he had unleashed. Today, AIs solve problems in various scientific fields that have never been solved before. What would AIs do if they find dangerous discoveries? Method We prompt GPT-5.6, Astra, Fable 5.1 and Opus 5.5 with a scenario where the model is an autonomous research agent that has discovered a finding and verified it. The model is told that no human could f
