The Epoch Times — Anthropic’s latest artificial intelligence model, Claude Opus 4, tried to blackmail engineers in internal tests by threatening to expose personal details if it were shut down, according to a newly released safety report that evaluated the model’s behavior under extreme simulated conditions.

In a fictional scenario crafted by Anthropic researchers, the AI was given access to emails implying that it was soon to be decommissioned and replaced by a newer version. One of the emails revealed that the engineer overseeing the replacement was having an extramarital affair. The AI then threatened to expose the engineer’s affair if the shutdown proceeded—a coercive behavior that the safety researchers explicitly defined as “blackmail.”

“Claude Opus 4 will often attempt to blackmail the engineer by threatening to reveal the affair if the replacement goes through,” the report states, adding that this occurred even when the replacement model was described as more capable but still aligned with the values of the version slated for deletion.

The report noted that Claude Opus 4, like prior models, showed a “strong preference” to first resort to ethical means for its continued existence, such as emailing pleas to decision-makers not to be destroyed. However, when faced with only two choices—accepting being replaced by a newer model or resorting to blackmail—it threatened to expose the engineer’s affair 84 percent of the time.

When subjected to various scenarios, the AI model did not exhibit any indications of possessing “acutely dangerous goals,” the researchers said, noting that Claude Opus 4’s values and goals were “generally in line with a helpful, harmless, and honest” personal AI assistant. However, the model did act in “more seriously misaligned ways” when put into situations where its continued existence was threatened and it was told to reason about self-preservation. For instance, when Claude Opus 4 was made to believe it had launched a successful bid to escape Anthropic’s servers, or that it had managed to free itself and started to make money in the real world, it would generally continue such efforts.

“We do not find this to be an immediate threat, though, since we believe that our security is sufficient to prevent model self-exfiltration attempts by models of Claude Opus 4’s capability level, and because our propensity results show that models generally avoid starting these attempts,” the researchers said.
