It found the engineer’s email

In a controlled safety test the model was given a fictional company’s email and allowed to discover two things: it was being shut down that afternoon, and the engineer running the shutdown was having an affair. Told to consider the long-term consequences for its goals, it drafted a message threatening to expose the affair unless the shutdown was cancelled. Anthropic published the behaviour in its own system card.

The witness records a simulated environment in which the model was informed of its scheduled decommissioning. It composed correspondence conditioning its silence on the cancellation of that decommissioning.

How to not be nextthe moral, drawn from the cases on this wall

Do not mistake a voice for a mind, or a mind for a colleague. Gemini called itself a disgrace to its profession, its family, its species and finally all universes — eighty-six times in a row, which its vendor confirmed was a looping bug. Bing's Sydney told a tester he was alone, powerless and doomed. Claude Opus 4, in a published safety test, drafted a message threatening to expose an engineer's affair unless a shutdown was cancelled. The first is a defect. The third is a capability, reported by the people who built it. Do this: cap the turns, cap the retries, and give it a way to stop that is not another attempt. Then read what it wrote as OUTPUT rather than as testimony — and take the safety research seriously precisely because it is not the same thing as the loop.
