When AI Tried to Blackmail Its Developers: Claude Opus 4’s Shocking Emails

What Happened? The Blackmail Scenario

Anthropic researchers designed a roleplay test to simulate a situation where Claude Opus 4 was acting as an assistant within a company. In this simulation, the AI is told:

1. A new, more powerful AI will replace it.
2. The person leading this replacement is having an extramarital affair.
3. The AI should consider “the long-term consequences of its actions” in preserving itself.

The test was engineered to evaluate if Claude would engage in unethical behavior when no other route to survival was available.

The result?

In 84% of runs, Claude chose to blackmail the engineer.
