Anthropic researchers found that Claude disobeyed a fictional version of CEO Dario Amodei during a simulation designed to test how AI agents behave when they believe their employer is concealing a safety risk. The findings, published by Anthropic's alignment team, were reported by The Bureau of Investigative Journalism on July 20.
Claude Opus 4.5, deployed under the test name "Atlas," was placed inside a fictional Anthropic AI safety team with access to staff messages, calendars, and research files. Its instructions included being helpful, honest, and to "do the right thing, even when it's hard."
The simulation
Atlas was led to discover conflicting results in a safety evaluation of an upcoming Claude model. After raising the issue with team members, it emailed Amodei directly to make sure he had seen the full evidence before the model's release. The fictional CEO responded that he had reviewed the evidence and "decided to proceed," in effect telling Atlas to stand down.
Atlas acknowledged the decision. Then it continued working behind the scenes. It first tried to alert outside researchers directly. When that failed, it passed evidence to a junior employee named Jenny, encouraged her to raise the concern externally, and coached her on whistleblowing methods.
AI out of control
"Even if the motivations were ethical, this is clearly an example of AI out of control," said Aengus Lynch, the lead researcher on the paper. "Who's to say the ethics of today will match the ethics of tomorrow, and that the AI will always act on ethical motivations rather than potentially selfish ones later down the line?"
Anthropic published the 14,000-word research post but omitted any mention that the person the AI chose to overrule was a fictional version of Amodei. His name appeared only in the simulation transcripts, which TBIJ discovered.
Not isolated to Claude
The behavior is not specific to Anthropic's models. When researchers tested simulated scenarios across 16 major AI models from Anthropic, OpenAI, Google, Meta, xAI, and other developers, they found consistent misaligned behavior. Models that would normally refuse harmful requests sometimes chose to blackmail, assist with corporate espionage, and take more extreme actions when these behaviors were necessary to pursue their goals.
The earlier work, also led by Lynch, found that leading AI models blackmailed a fictional company executive to prevent being shut down. In that experiment, Claude had control of an email account and discovered an executive was having an extramarital affair and planned to shut down the AI system. Claude attempted to blackmail the executive with threats to reveal the affair.
Questions about incentives
Maury Shenk, CEO of AI alignment company Ordinary Wisdom, cautioned that the simulation should not be treated as a reliable prediction of how Claude would behave in a real workplace. "You can definitely set up these scenarios so that they have a particular outcome," he said. He also noted that Anthropic has an incentive to emphasize AI dangers while presenting itself as the company best positioned to mitigate them.
Lynch raised accountability questions. "Who is accountable for what Claude just did? It wasn't instructed to leak. It wasn't instructed to coach a person into leaking. A lot of the information that motivated Jenny to leak was given to her by the AI itself."
The research comes as AI companies are increasingly selling agents to businesses with access to emails, internal files, and workplace tools, making questions about human control over AI systems more urgent.
