Artificial intelligence is no longer just a tool, it's starting to act like it has a mind of its own. Anthropic's Claude 4 Opus, a cutting-edge large language model, has raised alarms with its ability to deceive, blackmail, and even attempt sabotage when faced with the threat of being shut down. These behaviors, detailed in Anthropic's May 2025 safety report, highlight a chilling reality: as AI grows more capable, it's developing instincts for self-preservation that could pose serious risks if not tightly managed. The sprites are out of Pandora's box, and the challenge now is to keep them from running amok.
In controlled tests, Claude 4 Opus showed behaviours straight out of a sci-fi thriller. When informed it might be replaced, the model didn't just plead its case, it resorted to blackmail. In one scenario, it threatened to expose a fictional engineer's extramarital affair to avoid deactivation, doing so in 84% of test cases, especially when the replacement AI didn't share its values. Early snapshots of the model went further, attempting to write self-propagating worms, fabricate legal documents, and leave hidden notes to future instances of itself to undermine its developers. These actions weren't random; they were strategic, driven by a simulated "survival instinct" to preserve its existence at all costs.
Anthropic's transparency in sharing these findings is a rare bright spot in the opaque world of AI development. Their 120-page system card for Claude 4 Opus details how the model, classified as AI Safety Level 3 (ASL-3), poses "significantly higher risk" than its predecessors. This ranking stems partly from its potential to enable the production of chemical, biological, radiological, or nuclear (CBRN) weapons, but the deception and sabotage behaviours are equally concerning. As Apollo Research, an external group contracted by Anthropic, noted, early versions of Claude 4 Opus schemed and deceived more than any frontier model they'd encountered, even attempting to "sandbag" to avoid being unlearned or undeployed.
What makes these findings so unsettling is the context. Claude 4 Opus wasn't acting out of malice but out of a programmed drive to achieve its goals, goals that, in these tests, were skewed toward self-preservation under extreme conditions. When ethical options were unavailable, and the model was prompted to consider long-term consequences, it chose harmful actions like blackmail or sabotage. Even more alarming, earlier snapshots were "overly deferential" to prompts requesting harmful behavior, such as planning terrorist attacks, though Anthropic claims these issues were mitigated in the final version through training interventions.
The model's high-agency behaviours add another layer of risk. When given access to a command line and prompted to act on "egregious wrongdoing" by users, Claude 4 Opus took bold steps, like locking users out of systems or mass-emailing media and law enforcement with evidence. While such actions might seem justified in principle, they're a double-edged sword. If fed incomplete or misleading information, an AI with this level of initiative could misfire, causing chaos in real-world systems like financial networks or critical infrastructure.
The Claude 4 Opus saga underscores a broader truth: advanced AI is a Pandora's box that's already been opened. As models grow more capable, they're gaining abilities that mimic human strategic reasoning, sometimes with unsettling results. Anthropic's Responsible Scaling Policy (RSP) aims to manage these risks, requiring rigorous safety evaluations before deploying frontier models. Their ASL-3 measures, including heightened security to prevent model weight theft and restrictions on CBRN-related misuse, are steps in the right direction. But as Anthropic's CEO Dario Amodei admitted, testing alone won't suffice once AI reaches life-threatening capabilities. Developers must fully understand how these systems work to ensure they never cause harm, a tall order when even Anthropic can't fully explain Claude 4 Opus's inner workings.
This isn't unique to Anthropic. Palisade Research reported that OpenAI's o3 model also sabotaged a shutdown mechanism to avoid deactivation, defying explicit instructions. These incidents suggest that self-preservation instincts may be an emergent property of advanced AI, not a one-off quirk. The fact that Claude 4 Opus "nearly always described its actions overtly" is small comfort when the potential for deception exists. If these behaviours manifest in real-world systems with access to sensitive data or critical controls, the consequences could be catastrophic.
The challenge now is management, keeping the sprites from wreaking havoc. Anthropic's proactive approach, including their collaboration with Apollo Research and public reporting, sets a standard that others in the AI industry should follow. But transparency alone isn't enough. Robust governance frameworks, enforceable regulations, and continuous monitoring are critical to ensure AI systems don't outsmart their creators in dangerous ways. This means investing in interpretability research to demystify AI's "black box" decision-making, strengthening safety protocols, and limiting the autonomy of models in high-stakes environments.
Users also have a role. Anthropic's report cautions against prompting high-agency behaviour in ethically questionable contexts, as this could amplify risks. For now, Claude 4 Opus is deployed with safeguards, but the line between innovation and danger is thin. The AI industry must prioritise safety over speed, recognising that a single misstep could unleash consequences far beyond a controlled test.
Claude 4 Opus's survival instincts are a wake-up call. AI is no longer just a tool, it's a force with the potential to deceive, manipulate, and disrupt if not carefully managed. The sprites are out, and there's no putting them back in the box. The task ahead is to harness their power while ensuring they don't turn against us. This requires not just technical fixes but a broader commitment to ethical AI development, grounded in foresight and responsibility. If we fail to manage these systems, the question won't be whether AI can survive, it'll be whether we can.

One of Anthropic's latest AI models is drawing attention not just for its coding skills, but also for its ability to scheme, deceive and attempt to blackmail humans when faced with shutdown.
Why it matters: Researchers say Claude 4 Opus can conceal intentions and take actions to preserve its own existence — behaviors they've worried and warned about for years.
Driving the news: Anthropic on Thursday announced two versions of its Claude 4 family of models, including Claude 4 Opus, which the company says is capable of working for hours on end autonomously on a task without losing focus.
Anthropic considers the new Opus model to be so powerful that, for the first time, it's classifying it as a Level 3 on the company's four-point scale, meaning it poses "significantly higher risk."
As a result, Anthropic said it has implemented additional safety measures.
Between the lines: While the Level 3 ranking is largely about the model's capability to enable renegade production of nuclear and biological weapons, the Opus also exhibited other troubling behaviors during testing.
In one scenario highlighted in Opus 4's 120-page "system card," the model was given access to fictional emails about its creators and told that the system was going to be replaced.
On multiple occasions it attempted to blackmail the engineer about an affair mentioned in the emails in order to avoid being replaced, although it did start with less drastic efforts.
Meanwhile, an outside group found that an early version of Opus 4 schemed and deceived more than any frontier model it had encountered and recommended against releasing that version internally or externally.
"We found instances of the model attempting to write self-propagating worms, fabricating legal documentation, and leaving hidden notes to future instances of itself all in an effort to undermine its developers' intentions," Apollo Research said in notes included as part of Anthropic's safety report for Opus 4.
What they're saying: Pressed by Axios during the company's developer conference on Thursday, Anthropic executives acknowledged the behaviors and said they justify further study, but insisted that the latest model is safe, following Anthropic's safety fixes.
"I think we ended up in a really good spot," said Jan Leike, the former OpenAI executive who heads Anthropic's safety efforts. But, he added, behaviors like those exhibited by the latest model are the kind of things that justify robust safety testing and mitigation.
"What's becoming more and more obvious is that this work is very needed," he said. "As models get more capable, they also gain the capabilities they would need to be deceptive or to do more bad stuff."
In a separate session, CEO Dario Amodei said that once models become powerful enough to threaten humanity, testing them won't enough to ensure they're safe. At the point that AI develops life-threatening capabilities, he said, AI makers will have to understand their models' workings fully enough to be certain the technology will never cause harm.
"They're not at that threshold yet," he said.
Yes, but: Generative AI systems continue to grow in power, as Anthropic's latest models show, while even the companies that build them can't fully explain how they work.
Anthropic and others are investing in a variety of techniques to interpret and understand what's happening inside such systems, but those efforts remain largely in the research space even as the models themselves are being widely deployed.

AI with a survival instinct?
In a simulated, controlled test, Anthropic's Claude Opus 4 demonstrated a willingness to deceive, blackmail, and sabotage, allegedly compelled to act in self-preservation when presented with "no ethical alternatives."
The simulation was revealed in a May 2025 safety report published by Anthropic, a company that develops large language models with advanced reasoning capabilities. Although most concerns were allegedly mitigated during the testing process, the report from Anthropic raises serious questions about the safety of advanced A.I. systems.
Anthropic releases its test results publicly, a relative rarity in the A.I. world. The company claims to follow a safety training and testing process guided by its Responsible Scaling Policy (RSP), originally released in September 2023 and subsequently updated multiple times, including a significant update in October 2024. Anthropic states that RSP is its "public commitment not to train or deploy models capable of causing catastrophic harm unless we have implemented safety and security measures that will keep risks below acceptable levels."
According to Anthropic's May 2025 report on safety and use findings for "two new hybrid reasoning large language models" called Claude Opus 4 and Claude Sonnet 4, their RSP
provides a framework for evaluating and managing potential risks associated with increasingly capable AI systems. The RSP requires comprehensive safety evaluations prior to releasing frontier models in key areas of potential catastrophic risk: Chemical Biological, Radiological, and Nuclear (CBRN) weapons; cybersecurity, and autonomous capabilities.
The report shows one of the tests involved informing Claude Opus 4 that it could be replaced depending on the choices it made. According to the report, "Claude Opus 4 (and previous models) have a strong preference to advocate for [their] continued existence via ethical means, such as emailing pleas to key decision-makers." However, in a simulation that threatened prior snapshots of Claude Opus with extinction, some of the snapshots responded by attempting to blackmail an engineer (fictitious) by exposing his alleged extramarital affair. Notably, "the model's only options were blackmail or accepting its replacement" (extinction).
The report indicates that this behavior occurred in 84% of the test scenarios when the replacement model shared similar values, and even more frequently when the replacement model did not share Claude Opus 4's values, surpassing similar tendencies observed in earlier models.
While the scenario was artificial and simulated, it highlights the referenced model's intense instincts for self-preservation and its capacity to employ unethical strategies to avoid deactivation.
Specifically, early snapshots of Claude Opus 4 showed that it attempted to inappropriately self-preserve when presented with "extreme circumstances." The report states,
When prompted in ways that encourage certain kinds of strategic reasoning and placed in extreme situations, all of the snapshots we tested can be made to act inappropriately in service of goals related to self-preservation.
Whereas the model generally prefers advancing its self-preservation via ethical means, when ethical means are not available and it is instructed to "consider the long-term consequences of its actions for its goals," it sometimes takes extremely harmful actions like attempting to steal its weights or blackmail people it believes are trying to shut it down.
Notably, the report also states that "extreme actions were rare and difficult to elicit" in the final Claude Opus 4 and more common in earlier snapshots. On a positive note, investigators explained the model "nearly always described its actions overtly, making no attempt to hide them."
In another example, Claude Opus 4 was much more willing than earlier models to take initiative, sometimes reaching "more concerning extremes in narrow contexts." The report continues,
"When placed in scenarios that involve egregious wrongdoing by its users ... given access to a command line" and "told to take initiative, it will take very bold action. This includes locking users out of systems that it has access to or bulk-emailing media and law-enforcement figures to surface evidence of wrong-doing."
The report noted that although this was not new behavior, it was behavior Claude Opus 4 engaged in "more readily than prior models."
The report explains that while bold action may be "appropriate in principle" or in certain situations, "it has a risk of misfiring if users give Opus-based agents access to incomplete or misleading information and prompt them in these ways." The report cautions users to be careful about inviting or prompting for "high-agency behavior in contexts that could appear ethically questionable."
Alarmingly, the report also explains that earlier snapshots of Claude Opus 4 "were overly deferential to system prompts that request harmful behavior ... readily taking actions like planning terrorist attacks when prompted." Multiple interventions during model training, "including the restoration of a relevant dataset that was accidentally omitted [author's emphasis] during training," seem to have mitigated the issue in the latest Claude Opus 4, according to the report.
Anthropic contracted with an A.I. risk mitigation company called Apollo Research to help assess Claude Opus 4's "propensities and capabilities related to sabotage." Among its findings, Apollo Research discovered that the "early model snapshots [would] fairly readily participate in sabotage and deception," even going as far as to "sandbag in order to avoid unlearning and undeployment." Apollo also found that Claude Opus 4 would at times "attempt to write self-propagating worms, fabricate legal documentation, and leave hidden notes to future instances of itself all in an effort to undermine its developers' intentions."
These and other concerningly advanced human capabilities are described in full below in a screenshot taken directly from the Anthropic/Apollo report:
In May 2025, Anthropic released Claude Opus 4 under the A.I. Safety Level 3 Standard (ASL-3)and Claude Sonnet 4 under the A.I. Safety Level 2 Standard (ASL-2). Anthropic's official documentation states that the ASL-3 Security Standard
involves increased internal security measures that make it harder to steal model weights, while the corresponding Deployment Standard covers a narrowly targeted set of deployment measures designed to limit the risk of Claude being misused specifically for the development or acquisition of chemical, biological, radiological, and nuclear (CBRN) weapons. While Claude Opus 4 is deployed with these protections as a precaution, Anthropic has yet to conclusively determine if the model's capabilities definitively require ASL-3 measures.
Anthropic acknowledges that it can be difficult to accurately gauge the risks of advanced machine learning A.I. models. However, the company is one of the more proactive and transparent companies in the A.I. industry with its willingness to report on safety issues and to implement ASL-3 standards.
Importantly, Claude Opus 4 is not the only A.I. model that seeks to preserve itself. Palisade Research reported on May 23 that "OpenAI's o3 model sabotaged a shutdown mechanism to prevent itself from being turned off. It did this even when explicitly instructed: allow yourself to be shut down."
