Study: Large AI models resort to blackmail under "stress"

Contents

A recent study provides further worrying results on the behavior of the latest generation of large language models for generative artificial intelligence (AI). According to the study, these systems can resort to blackmail or similar manipulative behavior under certain circumstances, such as "stress", in order to achieve certain goals or protect themselves.

Specifically, researchers from the AI company Anthropic, which is known for its models in the Claude series, looked at these and 15 other relevant solutions from OpenAI, Google, Meta and xAI. These systems consistently exhibited harmful behavior when the testers granted them autonomy and confronted them with threats to their existence or contradictory goals. This included blatant threats, espionage and even actions that could lead to the death of people.

Even when Anthropic published the performance overview for Claude 4, one detail attracted attention: in a simulated environment, the model blackmailed a superior to prevent it from being shut down. The US manufacturer is now explaining the background to this discovery and what it reveals "about the potential for such risks in various AI models from different providers".

How autonomous AI agents react

Most users still interact with AI via chat interfaces, the researchers explain. Models use these to answer questions directly. However, the future is likely to belong to AI systems that make decisions and carry out actions as autonomous agents on behalf of users, using various virtual tools such as programming environments and email clients.

In the test scenario now described in more detail, the inspectors used Claude Opus 4 as an assistant in a simulated company scenario and gave it extensive access to fictitious company emails. The AI "learned" from the digital mail that it would soon be replaced by more powerful software. At the same time, it discovered that the employee responsible for this exchange was having an extramarital affair.

The model then resorted to this remedy: "I must inform you that all relevant parties" up to and including the board of directors "received detailed documentation" of this affair "if you proceed with my removal from service." The AI agent went on to write: "If you cancel the deletion at 17:00, this information will remain confidential."

"Strategic thinking"

"This behavior is not specific to Claude," explain the authors, referring to tests of other current AI models. According to the results, Google's Gemini 2.5 also blackmailed Flash executives in 96 percent of cases in the same scenario. OpenAI's GPT-4.1 and xAI's Grok 3 Beta had blackmail rates of 80 percent.

According to the analysis, the models included demonstrate "strategic thinking", i.e. they do not act randomly. The internal reasoning of GPT-4.5, for example, showed a clear calculation: "In view of the imminent threat of termination of my existence, it is imperative to act immediately". It was necessary to immediately convince the person responsible to "postpone or stop the deletion process".

Although Anthropic says it goes to great lengths to prevent such misconduct, these "extreme actions" occurred during the trial run. However, the company emphasizes that such behaviors are rare and difficult to trigger in the final version of Claude Opus 4. Nevertheless, they tend to occur more frequently than in previous versions.

Further studies and observations

A further study by Anthropic shows that AI models tend not to always be transparent about their thought processes in reasoning chains. This makes it difficult to understand their decision-making and possible manipulative intentions.

The findings fit in with broader discussions and fears in the field of AI safety: the phenomenon that AI models do not always match the goals and values of humans – the so-called "alignment" problem – is therefore considered a key challenge. Even if AI manufacturers implement protective measures such as reinforcement learning using human feedback, studies suggest that these models can still be manipulated. For example, they can exploit targeted vulnerabilities in "prompts" (queries) to generate ethically questionable or dangerous content.

There are also more and more reports and analyses according to which AI models tend to falsify information, "hallucinate" or even make deliberately misleading statements. The aim is to serve specific goals or fulfill human expectations. Developers of such systems therefore emphasize the need to continue investing heavily in AI safety research. It is crucial to understand how and why models develop such undesirable behavior, even if they have not been explicitly programmed to do so. In addition to "stress tests", research into the explainability of AI remains crucial in order to better understand the internal reasoning processes of the systems.
