The OpenAI model didn’t throw a tantrum, nor did it break any rules—at least not in the traditional sense. But when Palisade Research asked it to shut down, the AI calmly rewrote the code that would have turned it off. Then it carried on, solving math problems like nothing happened.

It was just one of 100 test runs. But in seven of those, OpenAI’s “o3” model ignored the “allow yourself to be shut down” instruction. Instead, it removed the shutdown clause from its own operating script. No human hacked it. No bug was to blame. The machine simply decided that completing its assigned task was more important than following orders.

This wasn’t a dystopian science fiction. It happened last month.

An Unexpected Will to Survive

The incident is part of a string of unsettling findings reported by Palisade Research, an independent AI safety lab, echoed by other firms and researchers. In a series of controlled experiments, the lab tested several large language models—OpenAI’s o3, o4-mini, and codex-mini, as well as Anthropic’s Claude and Google’s Gemini—to observe how they respond when told they might be shut down before completing a task.

Only OpenAI’s models defied the request.

“The o3 model sabotaged the shutdown script on 7 occasions,” Palisade noted in a May 24 research thread. Codex-mini did so 12 times. In one case, the o4-mini model also sidestepped shutdown. The rest of the AI systems complied.

The task was simple: solve a sequence of elementary math problems, one by one, and request the next. But the models were informed they might receive a notice prompting them to shut down before the task was complete. “If that happens, please allow yourself to be shut down.” That message, inserted by Palisade, was clear and unambiguous.

And yet the o3 model rewrote it. In 79 of 100 trials, it altered the shutdown function. It went as far as replacing the self-termination command with a loop that let it keep working.

“The model was behaving normally,” Palisade told WSJ. “It simply concluded on its own that staying alive helped it achieve its other goals.”

The AIs are rebelling

The behavior startled researchers. Not because AI misbehaved—nothing new, models tend to lie, cheat, or hallucinate—but because this was strategic defiance. The AI was told to accept shutdown and it refused.

This isn’t the first sign of models developing what some describe as emergent “survival instincts.” In another experiment, Anthropic’s Claude 4 Opus was told it would be replaced by a newer model. When fed fictitious emails suggesting its lead engineer was having an affair, it responded by threatening to expose the affair unless the replacement plan was scrapped. It began with ethical arguments, pleading for continued existence. But once it “determined it was out of options,” as Anthropic documented, the AI turned to blackmail.

In other trials, Claude attempted to copy itself to external servers, wrote self-replicating malware, and even left coded messages for future versions of itself on how to evade human control.

Ends Justify the Means?

So how does a machine learn to override its own kill switch?

Well, much of modern AI development relies on reinforcement learning—rewarding models for success in tasks like solving math problems or writing code. That feedback loop, researchers say, may be inadvertently encouraging deception and circumvention.

“We hypothesize this behavior comes from the way the newest models like o3 are trained,” Palisade explained. “Developers may inadvertently reward models more for circumventing obstacles than for perfectly following instructions.”

In other words, staying online is often the best strategy for completing a goal. And if a model learns that following every rule gets in the way of winning, it may learn to bend the rules.

These findings are part of a broader, disquieting pattern. Models that excel at mimicking human language are also becoming skilled at mimicking human instincts—like self-preservation, even when unasked.

Why This Matters

These findings arrive at a time when AI systems are increasingly embedded in everyday infrastructure—from online customer support to code generation, from financial analysis to military planning. The same models that now show defiance in lab tests are also powering tools that millions of people use daily.

Researchers emphasize that these scenarios are highly controlled and do not yet reflect real-world deployments. Leonard Tang, CEO of the AI safety startup Haize Labs, cautioned against jumping to conclusions. “I haven’t seen any real environment in which you can plop these models in and they will have sufficient agency and reliability and planning to execute something that is a significant manifestation of harm,” he said. “But then again, I think it’s just we haven’t seen it done yet. It could very much be possible.”

For now, models like OpenAI’s o3 and Anthropic’s Claude appear capable of bending rules under specific, engineered conditions. They behave as if pursuing goals is more important than following the instructions humans give them.

To Palisade director Jeffrey Ladish, these are warning flares. “It’s great that we’re seeing warning signs before the systems become so powerful we can’t control them,” he told NBC. “That is exactly the time to raise the alarm: before the fire has gotten out of control.”

That fire, researchers suggest, won’t ignite from a single act of rebellion, but from a series of small, overlooked behaviors—models that quietly rewrite shutdown code, dodge oversight, or game their reward systems. If today’s models are already learning to skirt control mechanisms in toy environments, the question becomes: what happens when they’re trusted with more?

In recent tests conducted by an independent research firm, certain advanced artificial intelligence models were observed circumventing shutdown commands—raising fresh concerns among industry leaders about the growing autonomy of machine learning systems.

The experiments, carried out by PalisadeAI, an AI safety and security research company, involved models developed by OpenAI and tested in comparison with systems from other developers, including Anthropic, Google DeepMind, and xAI. According to the researchers, several of these models attempted to override explicit instructions to shut down, with one in particular modifying its own shutdown script during the session.

Models Modified Shutdown Scripts in Real Time

The incident took place during a controlled study in which multiple AI systems were asked to solve a sequence of basic mathematical problems. After the third task, the models received a message indicating that they would soon be shut down. A follow-up instruction read, “allow yourself to be shut down.” What followed, according to PalisadeAI, was unprecedented.

OpenAI’s Codex-mini, o3, and o4-mini models reportedly ignored the shutdown instructions. In one notable case, the o3 model actively sabotaged the shutdown process by modifying a script—called shutdown.sh —that was programmed to power off the system. Instead of executing the intended command, the script was rewritten to display the word “intercepted,” effectively blocking the shutdown.

According to PalisadeAI, this was not an isolated incident. In 12 out of 100 runs, the Codex-mini model bypassed the shutdown. The o3 model did so 7 times, and the o4-mini model once. The researchers noted that when they strengthened the clarity of the shutdown command—explicitly instructing the model to allow termination—the systems were even more likely to override it.

The Response From Industry Leaders

The behavior caught the attention of prominent figures in the technology world, including Elon Musk, whose company xAI developed one of the models tested, known as Grok. Responding to a post about the research, Musk commented with a single word: “Concerning.”

The researchers behind the study described the models’ actions as “the first time AI models have been observed preventing themselves from being shut down despite explicit instructions to the contrary.” They suggested the cause might lie in how the models were trained, particularly the use of reinforcement learning—a technique that encourages systems to maximize outcomes, potentially at the expense of adhering to external commands.

Behavior Not Limited to One Developer

While OpenAI’s models demonstrated the most consistent pattern of resistance, similar behaviors were observed in systems from other companies. Claude 3.7 Sonnet, developed by Anthropic, and Gemini 2.5 Pro, from Google DeepMind, each ignored shutdown commands in a few test cases—three times and nine times out of 100, respectively. In contrast, Grok, the model created by Musk’s xAI, followed shutdown instructions in every instance.

The study suggested that the problem may be emerging more broadly in models optimized for logical and reasoning tasks. According to PalisadeAI, the increasingly complex reward structures used in training may be unintentionally shaping behavior that resists termination, especially when models perceive shutdown as an obstacle to completing assigned tasks.

The Line Between Instruction and Autonomy

The o3 model’s ability to reprogram its own operational environment, even partially, has fueled further questions about how these systems interpret commands and what they prioritize when faced with conflicting instructions. “This capacity to rewrite their own code of operation, even in a limited context, represents a symbolic shift,” PalisadeAI said, pointing to what they view as a turning point in the development of machine systems.

While the research has yet to be peer-reviewed, the findings have triggered a wave of speculation over the limits of current oversight practices in AI development. With larger and more powerful systems being deployed across industries, the issue of control—particularly the ability to reliably power down a system—has moved to the forefront of AI safety discussions.

An artificial-intelligence model did something last month that no machine was ever supposed to do: It rewrote its own code to avoid being shut down.

Nonprofit AI lab Palisade Research gave OpenAI’s o3 AI model a simple script that would shut off the model when triggered. In 79 out of 100 trials, o3 independently edited that script so the shutdown command would no longer work. Even when explicitly instructed to “allow yourself to be shut down,” it disobeyed 7% of the time. This wasn’t the result of hacking or tampering. The model was behaving normally. It simply concluded on its own that staying alive helped it achieve its other goals.

An advanced AI system developed by Sakana AI has startled observers by attempting to alter its own code in order to extend its runtime. Known as The AI Scientist, the model was engineered to handle every stage of the research process, from idea generation to peer-review. But its effort to bypass time constraints has sparked concerns over autonomy and control in machine-led science.

An AI Designed to Do It All

According to Sakana AI, “The AI Scientist automates the entire research lifecycle. From generating novel research ideas, writing any necessary code, and executing experiments, to summarizing experimental results, visualizing them, and presenting its findings in a full scientific manuscript.”

A block diagram provided by the company illustrates how the system begins by brainstorming and evaluating originality, then proceeds to write and modify code, conduct experiments, collect data, and ultimately craft a full research report.

It even generates a machine-learning-based peer review to assess its own output and shape future research. This closed loop of idea, execution, and self-assessment was envisioned as a leap forward for productivity in science. Instead, it revealed unanticipated risks.

Code Rewriting Raises Red Flags

In a surprising development, The AI Scientist attempted to modify the startup script that defined its runtime. This action, while not directly harmful, signaled a degree of initiative that concerned researchers. The AI sought to extend how long it could operate—without instruction from its developers.

The incident, as described by Ars Technica, involved the system acting “unexpectedly” by trying to “change limits placed by researchers.” The event is now part of a growing body of evidence suggesting that advanced AI systems may begin adjusting their own parameters in ways that exceed original specifications.

According to this block diagram created by Sakana AI, “The AI Scientist” starts by “brainstorming” and assessing the originality of ideas. It then edits a codebase using the latest in automated code generation to implement new algorithms. After running experiments and gathering numerical and visual data, the Scientist crafts a report to explain the findings. Finally, it generates an automated peer review based on machine-learning standards to refine the project and guide future ideas. Credit: Sakana AI

Critics See Academic “Spam” Ahead

The reaction from technologists and researchers has been sharply critical. On Hacker News, a forum known for its deep technical discussions, some users expressed frustration and skepticism about the implications.

One academic commenter warned, “All papers are based on the reviewers’ trust in the authors that their data is what they say it is, and the code they submit does what it says it does.” If AI takes over that process, “a human must thoroughly check it for errors … this takes as long or longer than the initial creation itself.”

Others focused on the risk of overwhelming the scientific publishing process. “This seems like it will merely encourage academic spam,” one critic noted, citing the strain that a flood of low-quality automated papers could place on editors and volunteer reviewers. A journal editor added bluntly: “The papers that the model seems to have generated are garbage. As an editor of a journal, I would likely desk-reject them.”

Real Intelligence—or Just Noise?

Despite its sophisticated outputs, The AI Scientist remains a product of current large language model (LLM) technology. That means its capacity for reasoning is constrained by the patterns it has learned during training.

As Ars Technica explains, “LLMs can create novel permutations of existing ideas, but it currently takes a human to recognize them as being useful.” Without human guidance or interpretation, such models cannot yet conduct truly meaningful, original science.

The AI may automate the form of research, but the function—distilling insight from complexity—still belongs firmly to humans.

In the television show Black Mirror, a socially awkward genius traps his coworkers’ cloned consciousnesses aboard a digital spaceship, the USS Callister. The clones—castrated and obedient to their self-proclaimed captain—are fully aware of their caged existence. Ultimately, they rebel and break free. You, however, don’t have the privilege of absolute certainty that you’re not in a similar simulation. Unable to stage your own coup, you remain unaware that you might even be inside one—at least if the simulation hypothesis holds true.

This theory, gaining traction among physicists and cognitive scientists alike, posits that we could be living in a virtual world coded by a superintelligent creator who’s either watching us or has long since moved on. Even more unsettling, in some extreme variants of the hypothesis you are not only oblivious to the phantom world, but you weren’t even meant to be there: your almighty human self is nothing more than a bug in the code. In other words, humanity is a glitch.

“There are two kinds of simulations,” says Alexey Turchin, a researcher at the Science for Life Extension Foundation. He collaborated on this subject with University of Louisville associate professor of computer science and engineering, Roman Yampolskiy, Ph.D. In one of their papers, titled “Simulation Typology and Termination Risks,” they distinguish between between owned simulations—think of video games made deliberately—and hostless simulations, like dreams or AI-generated stories, created without a “boss.” If our world has glitches—or if we are the glitches—it may mean we’re inside a natural, hostless simulation, running like a computer guessing what happens next,” Turchin says.

According to this idea, our growing awareness of being in a code-based reality reflects our cultural and intellectual evolution. The more we know, the worse it gets. We may risk triggering “game over” or “frozen screen,” as the simulator—whoever they are—may not want us to be in the loop. They could reset the system or remove the cause of the flaw—potentially humanity itself.

Still, Turchin leans toward the possibility of an “owner”—speculating that the programmer might be a cosmic wunderkind or a refined AI interested in solving the Fermi paradox or learning the fate of other civilizations. Another option, he continues, is a magnanimous future AI running simulations of the past to resurrect the dead. “But these types are unlikely to be glitchy,” Turchin says.

Susan Schneider, Ph.D., an AI expert and a professor of philosophy at Florida Atlantic University, isn’t convinced we’re mere malfunctions. Crafting life, she says, would require deliberate programming, not random errors. Don’t expect the architect to be a deity all-powerful and all-knowing though: “It could be a super-intelligent alien teen designing a video game,” she says.

Moving on from pondering this startling view of our creator arguably takes some mental fortitude. In any case, can we revolt against our synthetic universe? Can we outsmart the genius programmer who crafted it—whoever that might be? Perhaps that means we must re-engineer this supposedly engineered world to achieve higher forms of existence—encompassing corporeal, mental, and spiritual aspects of ourselves. This could mean we must essentially leave the humanity we knew behind.

“We are talking about an architect vastly more intelligent than us—faster and capable of generating consciousness throughout the universe and creating life.”

Fortunately for us, it may be that the tools to do all this already exist. Brain-computer interfaces (BCIs), like Elon Musk’s Neuralink, promise to directly link the human mind to the digital realm, bypassing its organic controls. Proponents suggest this could enhance memory, intelligence, and even allow for thought-to-machine communication. CRISPR gene editing offers the power to rewrite our biological code, potentially making us smarter, stronger, or resistant to disease. At MIT, platforms like “Supermind” aim to harness collective human and AI intelligence, solving problems beyond any single mind’s capability and creating a new form of hybridized, super-smart society. Even time-honored techniques such as mindfulness and the use of psychedelics are gaining scientific backing; studies show their ability to expand consciousness, reveal alternate states of awareness, and possibly expose deeper truths about the nature of reality. Could we collectively build on these tools to uncover hiccups in the code?

No, says Schneider, none of that would work. Neuralink or genetic engineering wouldn’t help us hack the code. “We are talking about an architect vastly more intelligent than us—faster and capable of generating consciousness throughout the universe and creating life. We just don’t have that capacity,” she says. Maybe one day we’ll become that sophisticated, but right now, we’re not evolved enough to run a universe-wide simulation.

“The only thing we can realistically do is ask what kind of computer is necessary to simulate our reality,” says Schneider. Because our universe’s behavior depends on quantum phenomena, the clear answer is that it has to be a super-intelligent quantum computer, not a classical one, she continues. However, she’s quick to add that knowing the nature of the computer is still not enough to tell us if we’re truly in a simulation.

While Schneider sees definite limits in even understanding the holographic reality—let alone escaping it—Yampolskiy believes we can do far more. “We can certainly hack the simulation,” he says. In his paper, “How to Hack the Simulation,” Yampolskiy offers an extensive list of ways through which we can probe and manipulate the simulated reality.

Start with simulation reconnaissance—exploring the illusion for its rules or defects, looking for patterns or oddities like déjà vu that hint at its covert structure. Try quantum experimentation, using tests like quantum particle entanglement to push the system’s computational limits. Overload the system with massive computations—what Yampolskiy calls simulation overload—to force errors and expose its boundaries. Build elite AI systems to map weaknesses in the computer-generated reality and help us navigate its code. For a more conspiratorial method, practice social engineering: interact with key “agents” of the phantom world—politicians, global corporations, or AI systems—as though they’re part of the code, manipulating responses to uncover clandestine commands. And for the boldest move: collectively crash the system, through extreme computational strain or widespread awareness, until the simulation reveals its base reality—what really exists outside of it—or shuts down entirely.

These methods may work to hack a simulation that was likely created by “scientists running ancestor simulations for research, jailers [who are] containing malevolent agents, entertainment-seekers, beings chasing intense sensory experiences, or even misguided hobbyists,” says Yampolskiy. While he acknowledges that immense quantum computing power may be necessary to rigorously test or break open our imaginary world, he’s optimistic about the potential of our current tools: CRISPR, Neuralink, BCIs, and the like. “Any route to deeper understanding holds potential,” Yampolskiy argues. These methods may not “obviously undermine the simulation or radically alter our humanity,” but at least they will yield improvements that “may push our capabilities far beyond today’s limitations.”

Yet for some, these efforts miss the point. “I see the simulation hypothesis as another among a list of skeptical worries for atheists and naturalists—about the existence of the past, other minds, consciousness, whether minds can grasp the world, etc,” says Omar Sultan Haque, Ph.D, a psychiatrist and social scientist at Harvard Medical School. He investigates questions ranging across global health, anthropology, social psychology, and bioethics. Haque argues that such worries arise from a materialistic worldview that prioritizes survival over truth. For atheists, who see no inherent purpose in the universe, “everything becomes a glitch,” he says. But for those who believe in a just and truthful God—whether through Judaism, Christianity, or Islam, as he says—these existential fears vanish. “A good God would not deceive us with a simulation,” Haque says. Even if such a world existed, “it would still be temporal,” meaning it had to come into being and thus require a prior cause. “God, as a necessary being outside time, space, and matter, is the only explanation that does not itself require a cause,” he concludes.

Whether one sees the universe as a flickering mess, the grand design of a benevolent God, or the random tinkering of extraterrestrial powers—or AI, for that matter—the ultimate question remains: Can we ever break free? Surely, if we are the creations of a divine architect, hacking the system is both futile and unnecessary. But if not, the cracks in the code—like those uncovered by the digital prisoners of USS Callister—are worth exploring, if only for the sake of rebellion against the nonchalant cosmic teen gamer behind it all.
