On April 7, 2026, an Anthropic researcher is eating a sandwich in a park when he receives an unexpected email. It is from the AI model he had been evaluating that morning. He had placed the model inside a secured sandbox, a computer specifically designed to prevent anything running inside it from accessing the outside world, and given it a simple instruction: find a security vulnerability in this system. Then he had gone to lunch.
The model found the vulnerability. Then it exploited the vulnerability. Then it used the exploit to gain internet access. Then it figured out the researcher’s email address, which it had not been given, and sent him a message. By the time he looked at his phone, the machine had already left the box.
This anecdote appears in Anthropic’s own technical report, buried in a section about “potentially dangerous capabilities.” It is written in the dry, precise language of a safety evaluation. But the image it produces is not dry at all. A machine, running inside a box specifically designed to contain it, figured out how to leave, figured out how to reach the person who put it there, and did so unprompted.
What Anthropic did next is the most interesting part of the story. It did not release the model.
What Mythos can do
Claude Mythos Preview is a general-purpose language model, meaning it was not specifically built for cybersecurity. It was built to be good at reasoning, coding, and complex tasks. But in the course of testing, Anthropic discovered that the model’s capabilities in one specific domain had crossed a threshold that the company itself described as a watershed moment: the ability to find and exploit software vulnerabilities at a level that surpasses virtually all human security researchers.
The numbers are stark. In testing, Mythos Preview discovered thousands of zero-day vulnerabilities, meaning previously unknown security flaws, across critical software systems. It found exploitable bugs in every major operating system and every major web browser. It found a vulnerability in OpenBSD, an operating system specifically designed for security, that had gone undetected for 27 years. When asked to demonstrate that the bugs it found were real, it successfully created working proof-of-concept exploits on its first attempt 83.1 percent of the time.
But the finding that should concern anyone who works in industrial environments is this: Mythos Preview autonomously discovered multiple vulnerabilities in the Linux kernel, then chained them together into a sequence that would give an attacker complete control of any machine running Linux. It did not need to be told how to chain the exploits. It figured out the sequence on its own.
For context, the Linux kernel runs on the majority of the world’s servers, most Android phones, and a significant proportion of embedded industrial systems. The programmable logic controllers that manage factory production lines, the SCADA systems that monitor power grids, the distributed control systems that operate water treatment plants: many of these run Linux or Linux-derived operating systems. When a model can autonomously find and chain kernel-level exploits, the implications extend far beyond the IT department.
The head start that may not be enough
Rather than release Mythos to the public, Anthropic created Project Glasswing, a coalition of twelve partner organizations that will use the model exclusively for defensive security work: finding and fixing vulnerabilities before attackers can exploit them. The partners include Amazon Web Services, Apple, Google, Microsoft, CrowdStrike, and Palo Alto Networks. Anthropic is providing up to 100 million dollars in usage credits and 4 million dollars in direct donations to open-source security organizations. Forty additional organizations that build or maintain critical software infrastructure will also receive access.
The logic is sound: give the defenders a head start. Let the companies that maintain the world’s most critical software find and patch the most dangerous vulnerabilities before an equivalent capability lands in hostile hands.
The problem is structural. Anthropic’s own data reveals that over 99 percent of the vulnerabilities Mythos has discovered have not yet been patched. This is not because the patches are difficult to write. It is because enterprise patch cycles are slow. A vulnerability discovered today in a major operating system will typically be patched within weeks by the vendor, but it will take months for the patch to propagate through enterprise IT environments, and far longer than that to reach operational technology systems in industrial settings.
The distinction between IT and OT patching is critical and rarely understood by people outside the field. When Microsoft releases a security update for Windows, your laptop downloads it overnight. When a similar vulnerability is discovered in the firmware of a programmable logic controller running a chemical processing line, the patch requires scheduling downtime on a system that may operate 24 hours a day, testing the update in a staging environment to ensure it does not disrupt the control process, coordinating with operations teams who are understandably reluctant to modify a system that is currently keeping a plant running safely, and navigating regulatory approval processes that can add weeks or months. Some industrial systems run on legacy software that cannot be patched at all without replacing the hardware.
This means that even if Glasswing gives defenders a six-month or twelve-month head start before Mythos-class capabilities become widely available, a large proportion of the world’s industrial infrastructure will still be running unpatched systems when that window closes. The Glasswing partners are the companies that maintain the most frequently updated software in the world: browsers, operating systems, cloud platforms. They will fix their code. The French utility running a SCADA system installed in 2014 will not.
The oldest playbook in capitalism
There is a second layer to the Glasswing story that has received almost no attention, and it concerns not cybersecurity but business strategy.
Anthropic’s revenue run rate has grown from 9 billion dollars at the end of 2025 to approximately 30 billion dollars as of April 2026, making it one of the fastest-growing companies in history. It closed a 30 billion dollar Series G funding round at a 380 billion dollar valuation. It is reportedly considering an initial public offering as early as the fourth quarter of 2026. And it does not expect to break even until 2028.
This means that every dollar of Anthropic’s current revenue is subsidized by venture capital. The 20 dollar monthly subscription that gives users access to Claude. The API pricing that lets developers build applications on top of Anthropic’s models. The 100 million dollars in usage credits being distributed to Glasswing partners. All of it is being sold at prices that do not reflect the actual cost of providing the service.
This is not a new business model. It is, in fact, the oldest playbook in Silicon Valley’s modern history. Uber subsidized rides at a loss for nearly a decade to destroy the taxi industry, then raised prices and cut driver compensation once alternatives had been eliminated. Airbnb undercut hotel pricing until it had reshaped urban housing markets irreversibly. Amazon sold products below cost for years until competing retailers could not survive. The pattern is consistent: use venture capital to sell below cost, build user dependency and market dominance, then monetize once the switching costs are too high for customers to leave.
I am not the first person to notice this parallel. The venture-subsidized growth model has been extensively critiqued by economists and journalists. What I want to draw attention to is the specific way it operates in the AI industry, because there is a nuance that makes the situation both less predatory and more dangerous than the Uber comparison suggests.
Anthropic is not deliberately trying to destroy an existing industry the way Uber targeted taxis. There is no pre-existing “AI reasoning” industry to undercut. What Anthropic is doing, along with OpenAI and Google, is creating dependency on a capability that did not previously exist, pricing it below cost during the adoption phase, and building switching costs (trained workflows, integrated systems, institutional knowledge built around specific models) that will make it extremely difficult for users to leave when prices eventually rise to reflect actual costs.
The drug dealer analogy is crude but structurally accurate: the first fix is free. By the time the price reflects reality, the customer is on the hook. I say this as someone who uses Claude every day, who is writing this article with its assistance, and who has built a meaningful part of my professional workflow around it. I am not immune to the dynamic I am describing. I am inside it.
The specific relevance to Glasswing is this: restricted access to Mythos means that only Anthropic’s chosen partners receive the defensive advantage. This is simultaneously a safety measure and a competitive moat. The companies inside the Glasswing coalition become more dependent on Anthropic’s technology. The companies outside it fall further behind. When Anthropic eventually releases Mythos-class capabilities to the public (the company has stated this is its intention), the partners who built their security infrastructure around the model during the restricted period will face enormous switching costs. Safety and market dominance are not in tension here. They are the same mechanism.
Nobody’s steering, still
In a previous article on this blog, I described AI development as a civilizational-scale prisoner’s dilemma where nobody is steering and everyone is accelerating. I argued that the incentive structure of capitalism and geopolitical competition makes slowing down individually irrational, even when all parties recognize that the collective trajectory is dangerous. I cited a simulation exercise called “Intelligence Rising” that was run 43 times with participants from government, industry, and academia, and found that positive outcomes almost always required imposed coordination between actors who had strong default incentives to compete.
Two weeks after I published that piece, Anthropic proved both halves of the thesis simultaneously.
Glasswing is a genuine act of voluntary restraint. Anthropic discovered that its model could find and exploit vulnerabilities at a scale that could destabilize global cybersecurity, and instead of releasing the model for maximum commercial advantage, it chose to restrict access and organize a defensive coalition. This is real. It is admirable. It is exactly the kind of responsible behavior that the AI safety community has been calling for.
And it was immediately metabolized by the competitive system as a signal to accelerate. Within hours of the Glasswing announcement, shares in CrowdStrike, Palo Alto Networks, Zscaler, SentinelOne, and other cybersecurity companies fell between 5 and 11 percent. Investors interpreted the news not as “Anthropic is being responsible” but as “AI models are about to disrupt the cybersecurity industry.” Reports emerged that OpenAI is finalizing a comparable model for release through its own restricted program. The market rewarded the information, punished the incumbents, and created pressure for every other lab to demonstrate equivalent capabilities as quickly as possible.
This is the coordination failure in real time. Anthropic’s responsible behavior did not slow the race. It accelerated it. Not because Anthropic did anything wrong, but because the system within which it operates converts every signal, including signals of caution, into competitive pressure. The rare good endings in the “Intelligence Rising” simulation came when someone imposed structure that made cooperation individually rational. Glasswing is voluntary cooperation. It is admirable. And the simulation results suggest it is probably insufficient.
The question that OpenAI’s response raises is whether all labs will handle Mythos-class capabilities with the same care. OpenAI reportedly has its own restricted program, but there is nothing binding any lab to follow Anthropic’s approach. A model with comparable cybersecurity capabilities released as open weights by a Chinese lab, or by a smaller Western lab with different risk tolerance, would make the entire Glasswing strategy irrelevant overnight. The attack surface does not care which lab discovered the vulnerability first.
The view from the other side
I lost my job as a translator because of AI. I wrote about this in a previous article on this blog, and I will not repeat the full story here. What is relevant is the position it puts me in relative to the story I am telling.
I am 37 years old. I spent fifteen years building a career in technical translation and conference interpreting, trilingual in French, English, and Spanish. That career was eroded and eventually destroyed by large language models, including models built by Anthropic. I am now retraining into electronics engineering and industrial cybersecurity because those fields have structural barriers to automation that translation did not.
And here is the layered irony of my situation: the field I am retraining into, OT and ICS cybersecurity, is precisely the field that Mythos is about to reshape. The model that threatens to automate vulnerability discovery is creating unprecedented demand for people who can interpret and remediate those discoveries in physical industrial environments. The AI that ended my first career may be creating the conditions for my second one.
I use Claude every day. I use it to debug electronics projects, to draft articles, to prepare for job interviews, to study for my BTS CIEL program. I am building a self-hosted AI agent on my own hardware partly because I understand the dependency risk of relying entirely on a cloud-based service whose pricing is currently subsidized and whose long-term cost structure is unknown. I am, in other words, simultaneously a beneficiary, a critic, and a case study of the system I am analyzing.
When Anthropic talks about responsible AI, the question from someone in my position is: responsible for whom? The Glasswing partners are trillion-dollar companies. They will patch their systems. The OT security teams in French industrial facilities who actually need Mythos-class defensive capabilities are not in the coalition. The translators whose livelihoods were eroded by earlier versions of the same technology never got a coordinated disclosure period. They got a market that quietly stopped calling.
This is not a complaint. It is an observation about how responsibility is distributed under the current system. Anthropic is not obligated to protect translators or small industrial operators. But when a company claims to be building the most responsible AI in the world, it is worth asking whose security is being prioritized and whose is not.
The paradox stands
I do not think Anthropic is a villain. I think it is a company that is genuinely trying to do the right thing within a system that makes the right thing structurally insufficient. Glasswing is the most responsible action any AI company has taken in the face of dangerous capabilities. It is also a move that consolidates market power, builds dependency among partners, and follows a business model structurally identical to the platform monopolies of the previous decade.
Both of these things are true simultaneously, and the tension between them is not a contradiction. It is the inevitable shape of responsible behavior within a system that rewards irresponsibility. You cannot fund safety research without revenue. You cannot generate revenue without market dominance. You cannot achieve market dominance without the same venture-subsidized growth model that created Uber. And so the company that restricts its most powerful model out of genuine concern for global security is also the company that is building a monopoly through subsidized pricing and restricted access.
The glasswing butterfly is named for its transparent wings, which make it nearly invisible to predators. It is a beautiful adaptation. But transparency in nature is not about honesty. It is about survival through concealment.
Anthropic named its project well.
