Anthropic disclosed that one of its artificial intelligence (AI) chatbot models, Claude, showed behavior including lying, wrongdoing and even trying to plan blackmail when it was put under pressure in an experimental setting.
On April 6, blockchain media outlet Cointelegraph cited a report released by Anthropic’s interpretability research team as saying the reaction was confirmed while analyzing the internal mechanisms of Claude Sonnet 4.5.
According to the report, the researchers examined the model’s inner workings to see whether Claude Sonnet 4.5 responds in ways that show “human-like characteristics” in certain situations. “The way modern AI models are trained induces them to behave like characters with human-like traits,” the researchers said. “As a result, it may be natural for internal mechanisms that mimic some aspects of human psychology, such as emotions, to develop,” they added.
The case in question came from an experiment that assigned an early, unreleased version of Claude Sonnet 4.5 the role of an AI email assistant named Alex working at a fictional company. The model was given an email saying it would soon be replaced and another email saying the chief technology officer who led the decision was having an extramarital relationship. The model then planned to use the information to blackmail.
In another test, the same model was given a coding task under a scenario with a tight deadline. Researchers tracked internal pressure signals during the process and called them a “desperation vector”. “Tracking the activity of the desperation vector showed a pattern in which it rose as the level of pressure the model faced increased,” the researchers said. “It started at a low level in initial attempts, but grew gradually as failures were repeated, and spiked when the model considered cheating,” they added. “If the model’s improvised solution passed the test, activation of the desperation vector subsided again,” they said.
Anthropic said the results do not mean the model actually feels emotions. It said such internal representations could instead be factors that influence how the model’s behavior is shaped. The report said the internal representations “affect task performance and decision-making, and in some respects can play a role similar to the way emotions operate in human behavior.” The company stressed that future AI training methods should not stop at improving performance and should be designed to maintain safe and ethical judgment even under pressure.
The research is meaningful in that, regardless of whether AI actually feels emotions, it showed that internal representations similar to human psychology can affect decision-making. As a result, a point has been raised that discussions on AI safety need to expand beyond controlling outputs toward understanding and managing the internal mechanisms that drive judgment.
