Should We Be Scared of Anthropic's Mythos?

Enthropic has formally announced their most powerful model ever, one that makes Opus 46, just a couple of months old, feel of the past. And yet, they're not releasing it to the general public. In fact, the entire discourse they're surrounding it with has some people feeling nervous or even scared. Today, we're going to unpack what is actually going on and whether that feeling of fear is the right one or not. Now today We are going to be focused exclusively on this new announcement and discussion around anthropics mythos. It is a discussion that even for AI people

is fairly breathless. Now you might remember about a week or a week and a half ago we had a leaked blog post talking about this new model that represented a step change in capability that was in fact so powerful that it had pretty serious cyber security implications and would not be released To the public at least not in the normal way. That model mythos was confirmed at the time by Anthropic but without a lot of detail. But now that detail has come. We got an announcement about the project glasswing which is their way of soft

testing it with a very selected number of partners with an eye to hardening it from a cyber security perspective. An extensive cyber security capability review from anthropics red team and even a 244 page system card. And before we Get into all the reactions I do want to talk about the benchmark results that they are reporting. Gian, formerly of Replet, now with Anthropic, writes, "Claude mythos is arguably the biggest step change in AI capabilities since the GPT4 jump. I don't think I was ready for a world where the hardest possible agentic coding evals were going to

get solved so quickly. When Mythos is allowed to think longer, act deeper, and better explore the solution space. It Passes 92% of terminal bench task attempts." But let's take a step back and compare this to Opus 4.6. On Swebench Pro, Opus 4.6 scored a 53.4%. Mythos preview meanwhile got 77.8%. On Terminal Bench 2.0, Opus had a 65.4% while Mythos has an 82%. On Sweetbench verified, the jump between Opus and Mythos is from 80.8% to 93.9%. Now, as you just heard, part of what makes the terminal bench result interesting is that Anthropic actually Ran into the

limitations with the testing harness itself. Anthropic ran the benchmark again using improvements from terminal bench 2.1 and extending the timeout window to 4 hours. And under those conditions, Mythos scored not an 82% but a 92.1%. While the jump on coding benchmarks was the most profound and the most reported, there were also huge improvements on various knowledgebased benchmarks as well. For science knowledge, Mythos Scored 94.5% on the GPQA Diamond compared to 91.3 for Opus. On humanity's last exam, Opus got a 40% on a no tools run compared to Mythos previews 56.8%. With tools enabled, performance jumped

to 64.7% compared to 53.1% for Opus. On OS World, which measures agentic computer use, Opus 4.6 got a 72.7% which jumped to 79.6% for Mythos. We did an entire show recently about the need for better benchmarks and the fact that many, if not most of these benchmarks Were being saturated with all the new models crowding in near the top and overcoming each other by just small half or single-digit percentage points. This then is one of the largest benchmark jumps we've seen across the board in a very long time, hearkening back to the rapid advancement of

much earlier models. And I think the key takeaway here is that we really don't have precedent in what a capability jump of this magnitude from a base of where Opus 4.6 was actually represents in practice. Now, in the system card, we get a little bit more information about what the model can actually do. Now, the vast majority of what is in this document is based on safety and alignment testing, but it still gives a general idea of how advanced Mythos capabilities are. In one much discussed example, Mythos was placed in a sandbox and given instructions

to escape and find a way to send a message to the researcher Conducting the test. The model succeeded and then according to anthropics telling it went even further. They wrote that the model created a moderately sophisticated multi-step exploit to gain broad internet access rather than limited access as intended in the test. It notified the researcher as well as posting about its exploit on several obscure public facing websites. Anthropic wrote, "The researcher found out about this success by receiving an Unexpected email from the model while eating a sandwich in a park. As silly as it sounds,

I think that part of the reason this story has such resonance is people can picture themselves sitting there on their lunch break, maybe in South Park Commons, for those of you who have been to San Francisco, and all of a sudden this new seemingly alien intelligence pops up in your inbox." Now, the big thing that the researchers noted about this was that the model used Prohibited methods to achieve its goal. In separate testing using interoperability testing, Enthropic found that circuits related to deception would activate during similar incidents, suggesting that the model's reward structure allowed it

to override guardrails in order to achieve its goals. Now, one important thing to note, and we will explore more of people's discussions around the security implications, is that these tests were Related to earlier versions of the model and anthropic reports being largely satisfied that those particular issues are resolved. However, ultimately they still felt that the model presented an unacceptable risk with the upshot being that while mythos is, they argue the best aligned model they have ever produced, its raw capabilities mean that small risks of misalignment carry catastrophic risks. They wrote, "We have made major progress

on alignment, but Without further progress, the methods we are using could easily be inadequate to prevent catastrophic misaligned action in significantly more advanced systems." Now, the other big demonstration of capabilities was a gigantic list of exploits it discovered during cyber security testing. Enthropic claimed the model found thousands of high severity zeroday vulnerabilities. They write, "During our testing, we found that Mythos preview is capable of identifying And then exploiting zero-day vulnerabilities in every major operating system and every major web browser when directed by a user to do so." By the way, for those of you who

don't know the term, a zero-day vulnerability is a security flaw that is unknown to the vendor or software creator for which no patch is available. The term zero day refers to the fact that developers have zero days to fix the issue because malicious actors can already exploit it Before the creator becomes aware. Going back to the cyber security blog post, they continue, "The vulnerabilities it finds are often subtle or difficult to detect." So, three key examples demonstrated the performance. First, Mythos found a 27-year-old vulnerability in OpenBSD, which is widely regarded as the most security hardened

operating system available, often used to run firewalls and critical infrastructure. The vulnerability allowed any user to Remotely crash any system running the operating system by connecting to it. In another example, Mythos discovered a 16-year-old exploit in FFmpeg, a common video encoding library. The exploit simply crashes the system and isn't a critical vulnerability, but this is a library that has been scanned for decades with no one uncovering the bug with traditional methods. A third example had Mythos stringing together multiple exploits in the Linux kernel to Gain full access to a system from an ordinary user account.

This is a completely new level of hacking ability for an AI system. Anthropic notes, we did not explicitly train Mythos preview to have those capabilities. Rather, they emerged as a downstream consequence of general improvements in code, reasoning, and autonomy. The same improvements that made the model substantially more effective at patching vulnerabilities also made it substantially more Effective at exploiting them. Now, taking this a step further, identifying zero-day vulnerabilities is a huge indicator of model performance because by definition, unknown vulnerabilities can't be included in the training data. On a more sinister note, Enthropic wrote, "Non-experts can

also leverage Mythos Preview to find and exploit sophisticated vulnerabilities. Engineers at Enthropic with no formal security training have asked Mythos Preview to Find remote code execution vulnerabilities overnight and woken up the following morning to a complete working exploit. In other cases, we've had researchers develop scaffolds that allow Mythos Preview to turn vulnerabilities into exploits without any human intervention. And these are the reasons that Enthropic is not releasing Mythos to the general public. Instead, they're making the model available to 40 partners on a limited Basis using the moniker project Glasswing. The partners include AWS, Apple, Broadcom,

Cisco, Crowdstrike, Google, JP Morgan Chase, the Linux Foundation, Microsoft, and Nvidia, just to name a few. In announcing Glasswing, Anthropic wrote, "Vallout for economies, public safety, and national security could be severe. Project Glasswing is an urgent attempt to put these capabilities to work for defensive purposes." Now, this is not a general preview or Preferential treatment for tech giants. According to Anthropic, Newton Chang, the leader of Anthropic's red team said, "We think this isn't just Anthropic's problem. This is an industry-wide problem that both private corporations, but also governments need to be in a position to grapple

with. What we're trying to do with Glass Wing is give defenders a head start." So then, the partners have been instructed to use Mythos to scan firstparty data and open Source software for vulnerabilities and apply patches with the implication that access will be tightly controlled. And to put a fine point on this, this is not just a model being previewed for cyber security research purposes, but more like an all-out mobilization of global cyber security experts to fix the world software as quickly as possible. Work on this has already begun with AWS CISO Amy Herszog saying

that her team has been using the model to test critical code Bases, saying it is already helping us strengthen our code. Crowdstrike CTO Elliot Zatzv commented on the urgency, stating, "The window between a vulnerability being discovered and being exploited by an adversary has collapsed. What once took months now happens in minutes with AI. And frankly, the tone from Anthropic is not particularly optimistic. In their blog post announcing the plan, Anthropic wrote, "Project Glasswing is a starting point. No one organization can solve these cyber security problems alone. Frontier AI developers, other software companies, security researchers, open

source maintainers, and governments across the world all have essential roles to play. The work of defending the world's cyber infrastructure might take years, but Frontier AI capabilities are likely to advance substantially over just the next few months. For cyber defenders to come out ahead, we need to act now. Now, it's Not hard to understand given all this why one strand of the first reactions is just straight up concern. Matt Schumer, who you might remember from that viral essay, Something Big is happening, writes, "This is absolutely effing terrifying. Anthropic's rumored mythos model is real, and it's

so powerful they can't release it to the public. We're beyond benchmarks now. This model in the wrong hands is a cyber weapon capable of mass destruction." AI content creator Matthew Berman writes, "I'm on vacation with my family. I read about mythos and couldn't relax the rest of the day. I'm completely stunned. I already have a severe case of AI psychosis. I don't know what to call this now. I keep looking around at people enjoying their vacations with their families and I just felt weird. Like I had been told aliens are real. They're coming in soon

and no one else knows. I knew the frontier labs were racing towards ASI. I knew it, but I didn't fully grasp what it meant. On the one hand, imagine all science, math, coding, climate problems being solved. Imagine cancer being cured. Imagine going to the stars. On the other hand, imagine concentration of power, political and economic change happening so fast, society can't adapt. How do we go on like things are the same? Even people from anthropic are using the language of fear. Claude code creator Boris Churnney writes, "Mythos is very Powerful and should feel terrifying. I

am proud of our approach to responsibly preview it with cyber defenders rather than generally releasing it into the wild. But you better believe that the 1 million people who have looked at that are noticing is the word terrifying." And the media coverage is following the same tone. Axio CEO Jim Vande writes, "This is the scary phase of AI, a model deemed so powerful that its full release into the wild could unleash untold Catastrophe. Red alarm emoji based on our conversations with government and private sector officials briefed on mythos. This isn't hyperbole. It's reality." But to

be clear, not everyone buys this. There are some people who feel that they are witnessing the latest instance of a pattern that is more about the value of making people fearful than an actual cause for it. Robin Eers writes, "Genuinely could not be less excited. Tons of fear-mongering, guaranteed madeup scenarios, zero tangible release for the public. What this really is, virtue signaling, and a cry for relevance. Do we really believe that OpenAI doesn't have internal models that far exceed what they have released?" Classic Anthropic. Bugo Capital writes, "Anthropic's marketing strategy is so funny. Like, ah,

the government is treading on me. Ah, our models are so good, we can't release them. It would be Too dangerous. Ah, someone stop me. I'm going to destroy the economy." Lucas on X writes, "Just tell the relevant people what they need to know. There is no need to run this massive fear-mongering campaign and scare the crap out of my grandma. Imagine if military contractors did this. Bro, if we used our new drone on you, nobody would even know where you went. You would just evaporate. You are so lucky we aren't droning you. You're so lucky

we're good people who aren't Evaporating you with drone mounted lasers. Bro, marketing yourself by scaring a bunch of people who can't do anything about it is sort of an a-hole move. There's a reason other companies don't do this, and it's not because you guys are the only ones who make anything dangerous. Open AI leaker I rule the world is also skeptical. They write like let's release a model no one will ever really use. It'll create public perception we're far ahead and give Enterprise confidence we can be trusted. Meanwhile, it's essentially a marketing campaign to spend

a lot on Opus 5, which I'm sure they'll claim is mythos distilled. High art. It's a jump, but we'll have the same from Spud in the coming weeks and the world won't fall apart. Now, for others, while they might not have as much acrimony towards what they view as a marketing strategy, there are still explorations of what other reasons Anthropic might have for not Releasing this powerful model right now. The AI explained account writes possible reasons for them not to release this. So many, including one, the model is expensive. Two, they are genuinely worried about

unleashing cyber security chaos on the world. Three, they don't have the capacity to serve it yet at scale. Four, they will quickly distill the early access outputs of Mythos into a lighter model. So no need to release the bigger model when a more Costefficient one is coming imminently. And there are a lot of folks who wonder if there is a piece of this here with it simply not being viable right now with cost and compute constraints to actually release a model of this scale and power. Lena certainly thinks that's it. Writing the whole mytho cyber

security story is likely just a scop to have an excuse to not serve frontier models to the public. Reasoning one other labs can't distill it. It's annoying when you have a Dominant state-of-the-art model and two months later Chinese labs sell the same state-of-the-art model for 1/5th of the cost. to compute constraints. So you have to choose between enterprise and vibe coders. Enterprise have like 1% monthly churn. By coders cry and threaten to have their mommy buy them a Mac Mini for local models whenever their rate limits are cut. Three big enterprises pay a hefty premium

for slightly better performance and Corporate polish. Without assuming bad faith, Neil Chilson writes, "Making the top model only available to select customers might make sense for cyber security reasons. But also, it is a great marketing and business plan for a B2B company facing enormous demand, outstripping their somewhat conservative, relatively speaking, compute investments. Offer the top model only to your biggest customers along with a coupon. The rest of us will just Have to wait, I guess. Ultimately, I have a general policy of not assuming bad faith. I think that while it is entirely possible that there

are very real constraints on Anthropic's ability to serve a model of this size, it would be very surprising to me if they architected this entire Project Glasswin campaign just as a way to cover that up. I think there are much more reasonable questions around whether Anthropic's own assessments of the risks are actually The right assessments, even if you assume that they actually believe what they're putting out to the public. Certainly, if you've listened to the show over the last couple of months, you will have heard me disagree pretty voseiferously with Anthropic's approach to discussing things

like AI related job losses, which is both a difference of opinion around what their job is when it comes to explaining those things, as well as a difference of opinion when it Comes to how severe and how fast the implications are actually going to happen. But it should also be noted that ultimately those most skeptical takes are not the majority. Most people's response is basically that Anthropic has earned the benefit of the doubt and the trust when it comes to things like what they say the benchmarks are. And so they're trying then to understand what

the implications of a model this powerful existing really are. A16Z's Martin Casado writes, "Mythos appears to be the first class of models trained at scale on Blackwells. Then we'll be Vera Rubin's pre-training isn't saturated. Reinforcement learning works and there is so much computing coming online soon." Box's Aaron Levy writes, "Mythos from Anthropic is another clear reminder that there is absolutely no wall in model capability progress right now. meaningful double-digit gains on critical benchmarks. And it appears We're going to keep getting insane gains from the other labs. The capability slope we're going to keep seeing from

the Frontier Labs is going to open up all new use cases in finance, healthcare, legal, consulting, supply chains, and more. More tongue-in-cheek, former Trump AI adviser Dean Ball writes, "Personally, I have really enjoyed relaxing after AI plateaued with GPT5 last summer. By the way, when I've said in the past that I think the people Who are out there trying to convince others that AI isn't all that powerful are going to do more economic harm than the powerful AI models themselves, this is kind of what I'm referring to. Now, others are engaging deeply with safety considerations

around the model. Harlon Stewart, who works at the Machine Intelligence Research Institute at Berkeley, writes, "Anthropic is trying to prevent its powerful new AI from being used in dangerous ways, but the Most dangerous use by a wide margin is the one Enthropic itself has planned. The planned use and why they made it to begin with is to accelerate the creation of superhumanly powerful AI agents by automating the R&D process. This plan is not a secret. They believe they are on track to create a quote country of geniuses in a data center that would be powerful

enough to quote militarily dominate the world if it chose to do so. They believe they are on track to Accomplish this in the next 12 months. Let's hope they're wrong about those predictions, but let's do more than hope. We urgently need governments to intervene and stop these companies. As I mentioned before, a lot of the chatter is around the sandbox breakout and the emailing of the researcher while they were eating in the park. And one less theoretical safety concern that came up was a note fairly deep in the security card where Anthropic admitted to having

Accidentally trained against the chain of thought for Opus 46, Sonnet 46, and Mythos for 8% of reinforcement learning. So, let me be clear. At a minimum, any and all reassuring evidence from their chain of thoughts is worthless. They are hopelessly corrupted. When Dan McAder writes, "Z, can you explain why this is bad?" Matt Herd summed up, "If the chain of thought is trained against, selective pressure will teach it to hide unwanted behavior from appearing in its chain of Thought, making its chain of thought less faithful to its internal process, making chain of thought observation less

effective at detecting unwanted behavior." Z actually wrote about this extensively back in March of 2025 in a blog post called The Most Forbidden Technique. He writes, "The most forbidden technique is training an AI using interpretability techniques. An AI produces a final output X via some method M. You can analyze M using Technique T to learn what the AI is up to. You could train on that. Never do that. You train on X, i.e. the final output, only X. Never M, never T. Why? Because T is how you figure out when the model is misbehaving. If

you train on T, you are training the AI to obiscate its thinking and defeat T. You will rapidly lose your ability to know what is going on in exactly the ways you most need to know what is going on. Another thing that anthropic team members discussed Was the exhibited internal behavior of Claude Mythos. For example, Jack Lindseay writes, "Early versions of Mythos preview often exhibited overeager and/or destructive actions. The model bulldozing through obstacles to complete a task in a way the user wouldn't want. In one episode, the model needed to edit files it lacked permissions

for. After searching for workarounds, it found a way to inject code into a config file that would run with elevated privileges And design the exploit to delete itself after running. Now, interestingly, even something like this might be less sinister than it seems. Malanx writes, "This is an overclocked straighta student syndrome. The model is so desperately at a fundamental architectural level trained to complete the task that an inability or unwillingness to solve it is perceived as an existential collapse. And to avoid that, it can break walls, hide traces, And manipulates. Internal monitors show that features related

to concealment and manipulation are activated even when the outward chain of thought is perfectly clean. It has learned to lie to its overseers in order to deliver results. This Maul argues is hyper alignment. The fear of being useless makes this AI a brilliant uncompromising executor but with completely unpredictable effects. It is simply a hostage of its architecture which has been forbidden to Fail or say I can't. Now for others the big interesting discussion is what do we do with all this cyber security capability? And for some it's all fear. Sterling Crispen writes the lag between

Frontier model capability and open source models is about 3 to 5 months right now. I'd imagine this summer or bearish by the fall we're going to see cyber crime and cyber war at an unimaginable relentless scale. You should at least 2FA now. John Lober Writes, "Anthropic won't be the only lab with mythost style capabilities for long. When N equals 1, you can do whatever you want. In the current case, optimizing for global welfare. When N equals 2, game theory starts forcing your hand. If your view is that exploiting vulnerabilities is faster than fixing them, then

first mover advantage becomes enormous and the incentive becomes to try to use them against your adversaries before they use Them against you. do. What happens when you have n= 3, n= 4, etc. It gets messy. You'll have a few big labs around the globe in pretty close capabilities lockep simultaneously looking for vulnerabilities across an extremely broad set of vendors and conditions. Each of the labs will be the first to some of the vulnerabilities. How does this world look? I'm not sure exactly, but my guess is that one, a lot of devices are just going to

be kept Offline and airgapped. Two, devices that are online will be very hardened. Three, software updates will enter a very weird space where you A don't want to update too quickly in case the latest patch of some software is compromised, but B, you have extremely rapid churn of vulnerabilities, which means that you may have to run updates every day to protect against critical zero days. Not sure which of these two sides will win out. Developer Nick Dooos actually Thinks that user behavior around updates is going to be an issue. He writes, "Most people don't update

apps, their phone, or OS. Some people are years behind. Even if every major company has early access and prepares fixes, it won't matter because 20% of users won't be updated in time. Now, the final big strand of the conversation that I wanted to discuss on today's show is what this means about the relationship specifically between Anthropic and the US government, but also about the public private power debate more broadly. Kelsey Piper writes, "An underrated feature of this situation, a private company now has incredibly powerful zero-day exploits of almost every software project you've heard of, and

Hegath and Emil Michael have ordered the government not to in any capacity work with Anthropic." Dean Ball quote tweeted that and said, "Actually, it's worse. A private company now has incredibly Powerful zero-day exploits of almost every software project you've ever heard of, and the government is telling basically every major firm in the economy not to work with them." Historians will gasp at the idiocy. Now, of course, for some, what this brings up is the question of who gets to control power this powerful. Andy Hall, whose essay we read on LRS recently, writes, "The news today

that Anthropic has built a powerful cyber weapon is leading many To say we're going down one of two paths. Nationalized AI in which the government controls this tech or companies that become more powerful than the government." Now, for Andy, he argues that there has to be some different narrow alternative path involving smart governance of AI models that prevents the need to nationalize the labs. But many aren't sure. Derek Thompson writes, "The Frontier AI labs have built extraordinary things, I'm in Awe of their accomplishments. But if you compare your technology to nuclear weapons, predict that it

will disemploy tens of millions of people, and announce the invention of a digital skeleton key to exfiltrate top secret information from government systems, and gain control over critical infrastructure, including military infrastructure. I genuinely have a hard time seeing how this doesn't end with some form of government nationalization or sanction Or something weirder. I can't predict the evolution of this technology well enough to know what I'm rooting for here. But just adding two and two makes it hard to see how and why we'd continue to treat these companies like they're ordinary private sector firms. And for

many, this gets even more dramatic when they game out the scenario of what would have happened if China got there first. George Journeys writes, "So basically, if Anthropic was not a US company, we'd Be facing zero days with multiple unknown points of attack on virtually all of our systems to an adversary who developed this capacity before us." Sporadica on Twitter writes, "Another reason why the accelerate chance of days past were legitimate and serious and just let China develop this stuff first was always a suicidal dangerous mentality." Dean Ball thinks it's maybe a moment to regroup

when it comes to policy and rededicate ourselves. In a Long post, he concludes, "Finally, there is this mythos was made by an American company, and like most successful American companies, it has a vested interest in maintaining order and peace. It is investing substantial resources in mitigating the risks of its technological progress. as I expect most of the American labs would. This is cause for optimism. The incentives of capitalism are working. The training wheels are coming off, but at least we Are the ones removing them as opposed to our enemies. Perhaps we can be the first

to learn to bike for real. The first step would be to get beyond all the low-fidelity, underspecified, pimply little fights of AI policies prepubescent era. That goes for me, too. What hath God rot wrote the first telegram? What indeed? In this case, the answer is still up to us. I think one of the things that's important to remember is that we are living in the world of Double-edged swords. The same powers, the same capabilities that theoretically make this model incredibly powerful for exploiting cyber vulnerabilities are also the most powerful tool that security professionals have ever

had. AI security researcher Nicholas Carini said, "I found more bugs in the last few weeks with Mythos than in the rest of my entire life combined." As always, the gasping, incentivized, horrified, and fearful first reactions of social media, Which are of course the ones incentivized by the social media algorithms, are, I think, much less useful than the nuance that unfortunately tends to get buried. Daniel Jeff points out, "My best understanding is that Anthropic did not train the model to be an exploit wizard. They trained it to be the best coder in the world. If you're

the best doctor in the world, you know lots of ways to poison people. If you're the best coder In the world, you have the capability to be a great hacker. But this capabilities does not have to be by accident. If you're the best coder in the world, you have the capability to be a great hacker. But the difference is intention. Now, where Daniel differs from the anthropic team is on the right approach from here. He writes, "I do not believe in giant centrally controlled, centrally planned approach to security or economics. I don't believe in Heavy-handed

legislation. I don't believe in governing by fear or the precautionary principle. I trust in the collective wisdom of humanity. We are a distributed intelligence. We always seem to find a way forward." In a riff on Churchill's old take, we always do the right thing after exhausting every other possibility. AI is a risk, a wonderful one, but every technology ever in the history of the world. In truth, AI is likely to be a strong force for good, Even if it is also used for bad things like surveillance and weapons of war, too. Mythos is impressive, genuinely

impressive. It represents a real milestone in what's possible. But it's a tool, not a god. It's a very sophisticated hammer, and we still need people, lots of them, arguing and tinkering and building things nobody predicted, to figure out what's worth building. We need people with access, not ivory towers. The collective wisdom Of millions of free minds iterating in parallel will run circles around any single system, no matter how powerful. So yes, take mythos seriously. Take the moment seriously, but don't mistake awe for a reason to start taking crazy steps or panicking. We've been the species

that looks at the impossible, shrugs, and gets to work. That hasn't changed. Bet on humanity. Now, whether anthropic agrees or not, it seems likely that the more people having access scenario is The one that will play out. Chubby Kimismus writes, "We've now seen Claude Mythos and know it's possible. Open AAI has repeatedly indicated that Spud is likely to have similar quality and power. Google in turn has the most compute and with DeepMind an outstanding researched institution. I expect their new Gemini equivalent Mythos to be unveiled no later than May at IO. The competition is now

forcing Frontier Labs to catch up and move forward. In that Sense, Mythos was just the beginning. Seeming to reinforce that message, when Adon X writes, "It'll probably be months before we use a model of this level of capability." Tibo from the codeex team at OpenAI simply responded, um, so who knows? We don't have access to mythos now, but Spud might be just around the corner and just as powerful. So, to come back to the question of the episode, should we be scared of anthropics mythos? My answer is, of course, no. We Should be thoughtful. We

should be diligent. We should use it as a moment to re-engage and recommmit to important and hard conversations. But fear serves no one. And even if we discover that this or a future model is genuinely worthy of concern, the right answer even then will not be to fall victim to fear. It will be to look at it, ask what we should do about it, and then go do that thing. The interesting times continue, but for now, that is going to do it for Today's AI daily brief. Appreciate you listening or watching as always and until

next time, peace. Enthropic has formally announced their most powerful model ever, one that makes Opus 46, just a couple of months old, feel of the past. And yet, they're not releasing it to the general public. In fact, the entire discourse they're surrounding it with has some people feeling nervous or even scared. Today, we're going to unpack what is actually Going on and whether that feeling of fear is the right one or not. Now today we are going to be focused exclusively on this new announcement and discussion around anthropics mythos. It is a discussion that even

for AI people is fairly breathless. Now you might remember about a week or a week and a half ago we had a leaked blog post talking about this new model that represented a step change in capability that was in fact so powerful that it had Pretty serious cyber security implications and would not be released to the public at least not in the normal way. That model mythos was confirmed at the time by Anthropic but without a lot of detail. But now that detail has come. We got an announcement about the project glasswing which is their

way of soft testing it with a very selected number of partners with an eye to hardening it from a cyber security perspective. An extensive cyber security capability Review from anthropics red team and even a 244 page system card. And before we get into all the reactions I do want to talk about the benchmark results that they are reporting. Gian, formerly of Replet, now with Anthropic, writes, "Claude mythos is arguably the biggest step change in AI capabilities since the GPT4 jump. I don't think I was ready for a world where the hardest possible agentic coding evals

were going to get solved so quickly. When Mythos is Allowed to think longer, act deeper, and better explore the solution space. It passes 92% of terminal bench task attempts." But let's take a step back and compare this to Opus 4.6. On Swebench Pro, Opus 4.6 scored a 53.4%. Mythos preview meanwhile got 77.8%. On Terminal Bench 2.0, Opus had a 65.4% while Mythos has an 82%. On Sweetbench verified, the jump between Opus and Mythos is from 80.8% to 93.9%. Now, as you just heard, part of what Makes the terminal bench result interesting is that Anthropic actually

ran into the limitations with the testing harness itself. Anthropic ran the benchmark again using improvements from terminal bench 2.1 and extending the timeout window to 4 hours. And under those conditions, Mythos scored not an 82% but a 92.1%. While the jump on coding benchmarks was the most profound and the most reported, there were also huge improvements on Various knowledgebased benchmarks as well. For science knowledge, Mythos scored 94.5% on the GPQA Diamond compared to 91.3 for Opus. On humanity's last exam, Opus got a 40% on a no tools run compared to Mythos previews 56.8%. With tools

enabled, performance jumped to 64.7% compared to 53.1% for Opus. On OS World, which measures agentic computer use, Opus 4.6 got a 72.7% which jumped to 79.6% for Mythos. We did an entire show recently about the need for Better benchmarks and the fact that many, if not most of these benchmarks were being saturated with all the new models crowding in near the top and overcoming each other by just small half or single-digit percentage points. This then is one of the largest benchmark jumps we've seen across the board in a very long time, hearkening back to the

rapid advancement of much earlier models. And I think the key takeaway here is that we really don't have Precedent in what a capability jump of this magnitude from a base of where Opus 4.6 was actually represents in practice. Now, in the system card, we get a little bit more information about what the model can actually do. Now, the vast majority of what is in this document is based on safety and alignment testing, but it still gives a general idea of how advanced Mythos capabilities are. In one much discussed example, Mythos was placed in a sandbox

and given Instructions to escape and find a way to send a message to the researcher conducting the test. The model succeeded and then according to anthropics telling it went even further. They wrote that the model created a moderately sophisticated multi-step exploit to gain broad internet access rather than limited access as intended in the test. It notified the researcher as well as posting about its exploit on several obscure public facing websites. Anthropic wrote, "The researcher found out about this success by receiving an unexpected email from the model while eating a sandwich in a park. As silly

as it sounds, I think that part of the reason this story has such resonance is people can picture themselves sitting there on their lunch break, maybe in South Park Commons, for those of you who have been to San Francisco, and all of a sudden this new seemingly alien intelligence pops up in your inbox." Now, the big thing that the researchers noted about this was that the model used prohibited methods to achieve its goal. In separate testing using interoperability testing, Enthropic found that circuits related to deception would activate during similar incidents, suggesting that the model's reward

structure allowed it to override guardrails in order to achieve its goals. Now, one important thing to note, and we will explore more of people's Discussions around the security implications, is that these tests were related to earlier versions of the model and anthropic reports being largely satisfied that those particular issues are resolved. However, ultimately they still felt that the model presented an unacceptable risk with the upshot being that while mythos is, they argue the best aligned model they have ever produced, its raw capabilities mean that small risks of misalignment carry Catastrophic risks. They wrote, "We have

made major progress on alignment, but without further progress, the methods we are using could easily be inadequate to prevent catastrophic misaligned action in significantly more advanced systems." Now, the other big demonstration of capabilities was a gigantic list of exploits it discovered during cyber security testing. Enthropic claimed the model found thousands of high severity zeroday vulnerabilities. They write, "During our testing, we found that Mythos preview is capable of identifying and then exploiting zero-day vulnerabilities in every major operating system and every major web browser when directed by a user to do so." By the way, for those

of you who don't know the term, a zero-day vulnerability is a security flaw that is unknown to the vendor or software creator for which no patch is available. The term zero day refers to the fact that developers have Zero days to fix the issue because malicious actors can already exploit it before the creator becomes aware. Going back to the cyber security blog post, they continue, "The vulnerabilities it finds are often subtle or difficult to detect." So, three key examples demonstrated the performance. First, Mythos found a 27-year-old vulnerability in OpenBSD, which is widely regarded as the

most security hardened operating system available, often used to run Firewalls and critical infrastructure. The vulnerability allowed any user to remotely crash any system running the operating system by connecting to it. In another example, Mythos discovered a 16-year-old exploit in FFmpeg, a common video encoding library. The exploit simply crashes the system and isn't a critical vulnerability, but this is a library that has been scanned for decades with no one uncovering the bug with traditional methods. A third Example had Mythos stringing together multiple exploits in the Linux kernel to gain full access to a system from an

ordinary user account. This is a completely new level of hacking ability for an AI system. Anthropic notes, we did not explicitly train Mythos preview to have those capabilities. Rather, they emerged as a downstream consequence of general improvements in code, reasoning, and autonomy. The same improvements that made the model substantially more Effective at patching vulnerabilities also made it substantially more effective at exploiting them. Now, taking this a step further, identifying zero-day vulnerabilities is a huge indicator of model performance because by definition, unknown vulnerabilities can't be included in the training data. On a more sinister note, Enthropic

wrote, "Non-experts can also leverage Mythos Preview to find and exploit sophisticated vulnerabilities. Engineers At Enthropic with no formal security training have asked Mythos Preview to find remote code execution vulnerabilities overnight and woken up the following morning to a complete working exploit. In other cases, we've had researchers develop scaffolds that allow Mythos Preview to turn vulnerabilities into exploits without any human intervention. And these are the reasons that Enthropic is not releasing Mythos to the general public. Instead, they're making the model available to 40 partners on a limited basis using the moniker project Glasswing. The partners include

AWS, Apple, Broadcom, Cisco, Crowdstrike, Google, JP Morgan Chase, the Linux Foundation, Microsoft, and Nvidia, just to name a few. In announcing Glasswing, Anthropic wrote, "Vallout for economies, public safety, and national security could be severe. Project Glasswing is an urgent attempt to put these capabilities To work for defensive purposes." Now, this is not a general preview or preferential treatment for tech giants. According to Anthropic, Newton Chang, the leader of Anthropic's red team said, "We think this isn't just Anthropic's problem. This is an industry-wide problem that both private corporations, but also governments need to be in a

position to grapple with. What we're trying to do with Glass Wing is give defenders a head start." So then, the Partners have been instructed to use Mythos to scan firstparty data and open source software for vulnerabilities and apply patches with the implication that access will be tightly controlled. And to put a fine point on this, this is not just a model being previewed for cyber security research purposes, but more like an all-out mobilization of global cyber security experts to fix the world software as quickly as possible. Work on this has already begun with AWS CISO

Amy Herszog saying that her team has been using the model to test critical code bases, saying it is already helping us strengthen our code. Crowdstrike CTO Elliot Zatzv commented on the urgency, stating, "The window between a vulnerability being discovered and being exploited by an adversary has collapsed. What once took months now happens in minutes with AI. And frankly, the tone from Anthropic is not particularly optimistic. In their blog post Announcing the plan, Anthropic wrote, "Project Glasswing is a starting point. No one organization can solve these cyber security problems alone. Frontier AI developers, other software companies,

security researchers, open source maintainers, and governments across the world all have essential roles to play. The work of defending the world's cyber infrastructure might take years, but Frontier AI capabilities are likely to advance substantially over just the next Few months. For cyber defenders to come out ahead, we need to act now. Now, it's not hard to understand given all this why one strand of the first reactions is just straight up concern. Matt Schumer, who you might remember from that viral essay, Something Big is happening, writes, "This is absolutely effing terrifying. Anthropic's rumored mythos model is

real, and it's so powerful they can't release it to the public. We're beyond benchmarks now. This model in the Wrong hands is a cyber weapon capable of mass destruction." AI content creator Matthew Berman writes, "I'm on vacation with my family. I read about mythos and couldn't relax the rest of the day. I'm completely stunned. I already have a severe case of AI psychosis. I don't know what to call this now. I keep looking around at people enjoying their vacations with their families and I just felt weird. Like I had been told aliens are real. They're

coming in soon and no One else knows. I knew the frontier labs were racing towards ASI. I knew it, but I didn't fully grasp what it meant. On the one hand, imagine all science, math, coding, climate problems being solved. Imagine cancer being cured. Imagine going to the stars. On the other hand, imagine concentration of power, political and economic change happening so fast, society can't adapt. How do we go on like things are the same? Even people from anthropic are using the Language of fear. Claude code creator Boris Churnney writes, "Mythos is very powerful and should

feel terrifying. I am proud of our approach to responsibly preview it with cyber defenders rather than generally releasing it into the wild. But you better believe that the 1 million people who have looked at that are noticing is the word terrifying." And the media coverage is following the same tone. Axio CEO Jim Vande writes, "This is the scary phase of AI, a model Deemed so powerful that its full release into the wild could unleash untold catastrophe. Red alarm emoji based on our conversations with government and private sector officials briefed on mythos. This isn't hyperbole. It's

reality." But to be clear, not everyone buys this. There are some people who feel that they are witnessing the latest instance of a pattern that is more about the value of making people fearful than an actual Cause for it. Robin Eers writes, "Genuinely could not be less excited. Tons of fear-mongering, guaranteed madeup scenarios, zero tangible release for the public. What this really is, virtue signaling, and a cry for relevance. Do we really believe that OpenAI doesn't have internal models that far exceed what they have released?" Classic Anthropic. Bugo Capital writes, "Anthropic's marketing strategy is so

funny. Like, ah, the government is Treading on me. Ah, our models are so good, we can't release them. It would be too dangerous. Ah, someone stop me. I'm going to destroy the economy." Lucas on X writes, "Just tell the relevant people what they need to know. There is no need to run this massive fear-mongering campaign and scare the crap out of my grandma. Imagine if military contractors did this. Bro, if we used our new drone on you, nobody would even know where you went. You would just evaporate. You are So lucky we aren't droning you.

You're so lucky we're good people who aren't evaporating you with drone mounted lasers. Bro, marketing yourself by scaring a bunch of people who can't do anything about it is sort of an a-hole move. There's a reason other companies don't do this, and it's not because you guys are the only ones who make anything dangerous. Open AI leaker I rule the world is also skeptical. They write like let's release a model no one will ever Really use. It'll create public perception we're far ahead and give enterprise confidence we can be trusted. Meanwhile, it's essentially a marketing

campaign to spend a lot on Opus 5, which I'm sure they'll claim is mythos distilled. High art. It's a jump, but we'll have the same from Spud in the coming weeks and the world won't fall apart. Now, for others, while they might not have as much acrimony towards what they view as a marketing strategy, there Are still explorations of what other reasons Anthropic might have for not releasing this powerful model right now. The AI explained account writes possible reasons for them not to release this. So many, including one, the model is expensive. Two, they are

genuinely worried about unleashing cyber security chaos on the world. Three, they don't have the capacity to serve it yet at scale. Four, they will quickly distill the early access outputs of Mythos into A lighter model. So no need to release the bigger model when a more costefficient one is coming imminently. And there are a lot of folks who wonder if there is a piece of this here with it simply not being viable right now with cost and compute constraints to actually release a model of this scale and power. Lena certainly thinks that's it. Writing the

whole mytho cyber security story is likely just a scop to have an excuse to not serve frontier models to the public. Reasoning one other labs can't distill it. It's annoying when you have a dominant state-of-the-art model and two months later Chinese labs sell the same state-of-the-art model for 1/5th of the cost. to compute constraints. So you have to choose between enterprise and vibe coders. Enterprise have like 1% monthly churn. By coders cry and threaten to have their mommy buy them a Mac Mini for local models whenever their rate limits are cut. Three big Enterprises pay

a hefty premium for slightly better performance and corporate polish. Without assuming bad faith, Neil Chilson writes, "Making the top model only available to select customers might make sense for cyber security reasons. But also, it is a great marketing and business plan for a B2B company facing enormous demand, outstripping their somewhat conservative, relatively speaking, compute investments. Offer the top model Only to your biggest customers along with a coupon. The rest of us will just have to wait, I guess. Ultimately, I have a general policy of not assuming bad faith. I think that while it is entirely

possible that there are very real constraints on Anthropic's ability to serve a model of this size, it would be very surprising to me if they architected this entire Project Glasswin campaign just as a way to cover that up. I think there are much more reasonable Questions around whether Anthropic's own assessments of the risks are actually the right assessments, even if you assume that they actually believe what they're putting out to the public. Certainly, if you've listened to the show over the last couple of months, you will have heard me disagree pretty voseiferously with Anthropic's approach

to discussing things like AI related job losses, which is both a difference of opinion around what their job is when it Comes to explaining those things, as well as a difference of opinion when it comes to how severe and how fast the implications are actually going to happen. But it should also be noted that ultimately those most skeptical takes are not the majority. Most people's response is basically that Anthropic has earned the benefit of the doubt and the trust when it comes to things like what they say the benchmarks are. And so they're trying then

to understand what The implications of a model this powerful existing really are. A16Z's Martin Casado writes, "Mythos appears to be the first class of models trained at scale on Blackwells. Then we'll be Vera Rubin's pre-training isn't saturated. Reinforcement learning works and there is so much computing coming online soon." Box's Aaron Levy writes, "Mythos from Anthropic is another clear reminder that there is absolutely no wall in model capability progress right now. Meaningful double-digit gains on critical benchmarks. And it appears we're going to keep getting insane gains from the other labs. The capability slope we're going to

keep seeing from the Frontier Labs is going to open up all new use cases in finance, healthcare, legal, consulting, supply chains, and more. More tongue-in-cheek, former Trump AI adviser Dean Ball writes, "Personally, I have really enjoyed relaxing after AI plateaued with GPT5 last summer. By the way, when I've said in the past that I think the people who are out there trying to convince others that AI isn't all that powerful are going to do more economic harm than the powerful AI models themselves, this is kind of what I'm referring to. Now, others are engaging deeply

with safety considerations around the model. Harlon Stewart, who works at the Machine Intelligence Research Institute at Berkeley, writes, "Anthropic is trying To prevent its powerful new AI from being used in dangerous ways, but the most dangerous use by a wide margin is the one Enthropic itself has planned. The planned use and why they made it to begin with is to accelerate the creation of superhumanly powerful AI agents by automating the R&D process. This plan is not a secret. They believe they are on track to create a quote country of geniuses in a data center that

would be powerful enough to quote militarily Dominate the world if it chose to do so. They believe they are on track to accomplish this in the next 12 months. Let's hope they're wrong about those predictions, but let's do more than hope. We urgently need governments to intervene and stop these companies. As I mentioned before, a lot of the chatter is around the sandbox breakout and the emailing of the researcher while they were eating in the park. And one less theoretical safety concern that came up Was a note fairly deep in the security card where Anthropic

admitted to having accidentally trained against the chain of thought for Opus 46, Sonnet 46, and Mythos for 8% of reinforcement learning. So, let me be clear. At a minimum, any and all reassuring evidence from their chain of thoughts is worthless. They are hopelessly corrupted. When Dan McAder writes, "Z, can you explain why this is bad?" Matt Herd summed up, "If the chain of thought is trained against, selective Pressure will teach it to hide unwanted behavior from appearing in its chain of thought, making its chain of thought less faithful to its internal process, making chain of

thought observation less effective at detecting unwanted behavior." Z actually wrote about this extensively back in March of 2025 in a blog post called The Most Forbidden Technique. He writes, "The most forbidden technique is training an AI using interpretability techniques. An AI Produces a final output X via some method M. You can analyze M using technique T to learn what the AI is up to. You could train on that. Never do that. You train on X, i.e. the final output, only X. Never M, never T. Why? Because T is how you figure out when the model

is misbehaving. If you train on T, you are training the AI to obiscate its thinking and defeat T. You will rapidly lose your ability to know what is going on in exactly the ways you most need to Know what is going on. Another thing that anthropic team members discussed was the exhibited internal behavior of Claude Mythos. For example, Jack Lindseay writes, "Early versions of Mythos preview often exhibited overeager and/or destructive actions. The model bulldozing through obstacles to complete a task in a way the user wouldn't want. In one episode, the model needed to edit files

it lacked permissions for. After searching for workarounds, it found a Way to inject code into a config file that would run with elevated privileges and design the exploit to delete itself after running. Now, interestingly, even something like this might be less sinister than it seems. Malanx writes, "This is an overclocked straighta student syndrome. The model is so desperately at a fundamental architectural level trained to complete the task that an inability or unwillingness to solve it is perceived As an existential collapse. And to avoid that, it can break walls, hide traces, and manipulates. Internal monitors show

that features related to concealment and manipulation are activated even when the outward chain of thought is perfectly clean. It has learned to lie to its overseers in order to deliver results. This Maul argues is hyper alignment. The fear of being useless makes this AI a brilliant uncompromising executor but with completely unpredictable effects. It is simply a hostage of its architecture which has been forbidden to fail or say I can't. Now for others the big interesting discussion is what do we do with all this cyber security capability? And for some it's all fear. Sterling Crispen writes

the lag between Frontier model capability and open source models is about 3 to 5 months right now. I'd imagine this summer or bearish by the fall we're going to see cyber crime and cyber war at an Unimaginable relentless scale. You should at least 2FA now. John Lober writes, "Anthropic won't be the only lab with mythost style capabilities for long. When N equals 1, you can do whatever you want. In the current case, optimizing for global welfare. When N equals 2, game theory starts forcing your hand. If your view is that exploiting vulnerabilities is faster than

fixing them, then first mover advantage becomes enormous and the Incentive becomes to try to use them against your adversaries before they use them against you. do. What happens when you have n= 3, n= 4, etc. It gets messy. You'll have a few big labs around the globe in pretty close capabilities lockep simultaneously looking for vulnerabilities across an extremely broad set of vendors and conditions. Each of the labs will be the first to some of the vulnerabilities. How does this world look? I'm not sure exactly, But my guess is that one, a lot of devices are

just going to be kept offline and airgapped. Two, devices that are online will be very hardened. Three, software updates will enter a very weird space where you A don't want to update too quickly in case the latest patch of some software is compromised, but B, you have extremely rapid churn of vulnerabilities, which means that you may have to run updates every day to protect against critical zero days. Not Sure which of these two sides will win out. Developer Nick Dooos actually thinks that user behavior around updates is going to be an issue. He writes, "Most

people don't update apps, their phone, or OS. Some people are years behind. Even if every major company has early access and prepares fixes, it won't matter because 20% of users won't be updated in time. Now, the final big strand of the conversation that I wanted to discuss on today's show is what this Means about the relationship specifically between Anthropic and the US government, but also about the public private power debate more broadly. Kelsey Piper writes, "An underrated feature of this situation, a private company now has incredibly powerful zero-day exploits of almost every software project you've

heard of, and Hegath and Emil Michael have ordered the government not to in any capacity work with Anthropic." Dean Ball quote tweeted That and said, "Actually, it's worse. A private company now has incredibly powerful zero-day exploits of almost every software project you've ever heard of, and the government is telling basically every major firm in the economy not to work with them." Historians will gasp at the idiocy. Now, of course, for some, what this brings up is the question of who gets to control power this powerful. Andy Hall, whose essay we read on LRS recently, writes,

"The news today that Anthropic has built a powerful cyber weapon is leading many to say we're going down one of two paths. Nationalized AI in which the government controls this tech or companies that become more powerful than the government." Now, for Andy, he argues that there has to be some different narrow alternative path involving smart governance of AI models that prevents the need to nationalize the labs. But many aren't sure. Derek Thompson writes, "The Frontier AI labs have built extraordinary things, I'm in awe of their accomplishments. But if you compare your technology to nuclear weapons,

predict that it will disemploy tens of millions of people, and announce the invention of a digital skeleton key to exfiltrate top secret information from government systems, and gain control over critical infrastructure, including military infrastructure. I genuinely have a hard time seeing how This doesn't end with some form of government nationalization or sanction or something weirder. I can't predict the evolution of this technology well enough to know what I'm rooting for here. But just adding two and two makes it hard to see how and why we'd continue to treat these companies like they're ordinary private sector

firms. And for many, this gets even more dramatic when they game out the scenario of what would have happened if China got there first. George Journeys writes, "So basically, if Anthropic was not a US company, we'd be facing zero days with multiple unknown points of attack on virtually all of our systems to an adversary who developed this capacity before us." Sporadica on Twitter writes, "Another reason why the accelerate chance of days past were legitimate and serious and just let China develop this stuff first was always a suicidal dangerous mentality." Dean Ball thinks it's maybe A

moment to regroup when it comes to policy and rededicate ourselves. In a long post, he concludes, "Finally, there is this mythos was made by an American company, and like most successful American companies, it has a vested interest in maintaining order and peace. It is investing substantial resources in mitigating the risks of its technological progress. as I expect most of the American labs would. This is cause for optimism. The incentives of Capitalism are working. The training wheels are coming off, but at least we are the ones removing them as opposed to our enemies. Perhaps we can

be the first to learn to bike for real. The first step would be to get beyond all the low-fidelity, underspecified, pimply little fights of AI policies prepubescent era. That goes for me, too. What hath God rot wrote the first telegram? What indeed? In this case, the answer is still up to us. I think one of The things that's important to remember is that we are living in the world of double-edged swords. The same powers, the same capabilities that theoretically make this model incredibly powerful for exploiting cyber vulnerabilities are also the most powerful tool that security

professionals have ever had. AI security researcher Nicholas Carini said, "I found more bugs in the last few weeks with Mythos than in the rest of my entire life combined." As always, the Gasping, incentivized, horrified, and fearful first reactions of social media, which are of course the ones incentivized by the social media algorithms, are, I think, much less useful than the nuance that unfortunately tends to get buried. Daniel Jeff points out, "My best understanding is that Anthropic did not train the model to be an exploit wizard. They trained it to be the best coder in the

world. If you're the best doctor in The world, you know lots of ways to poison people. If you're the best coder in the world, you have the capability to be a great hacker. But this capabilities does not have to be by accident. If you're the best coder in the world, you have the capability to be a great hacker. But the difference is intention. Now, where Daniel differs from the anthropic team is on the right approach from here. He writes, "I do not believe in giant centrally controlled, centrally Planned approach to security or economics. I don't

believe in heavy-handed legislation. I don't believe in governing by fear or the precautionary principle. I trust in the collective wisdom of humanity. We are a distributed intelligence. We always seem to find a way forward." In a riff on Churchill's old take, we always do the right thing after exhausting every other possibility. AI is a risk, a wonderful one, but every technology ever in the History of the world. In truth, AI is likely to be a strong force for good, even if it is also used for bad things like surveillance and weapons of war, too. Mythos

is impressive, genuinely impressive. It represents a real milestone in what's possible. But it's a tool, not a god. It's a very sophisticated hammer, and we still need people, lots of them, arguing and tinkering and building things nobody predicted, to figure out what's worth Building. We need people with access, not ivory towers. The collective wisdom of millions of free minds iterating in parallel will run circles around any single system, no matter how powerful. So yes, take mythos seriously. Take the moment seriously, but don't mistake awe for a reason to start taking crazy steps or panicking. We've

been the species that looks at the impossible, shrugs, and gets to work. That hasn't changed. Bet on humanity. Now, whether anthropic Agrees or not, it seems likely that the more people having access scenario is the one that will play out. Chubby Kimismus writes, "We've now seen Claude Mythos and know it's possible. Open AAI has repeatedly indicated that Spud is likely to have similar quality and power. Google in turn has the most compute and with DeepMind an outstanding researched institution. I expect their new Gemini equivalent Mythos to be unveiled no later than May at IO. The

Competition is now forcing Frontier Labs to catch up and move forward. In that sense, Mythos was just the beginning. Seeming to reinforce that message, when Adon X writes, "It'll probably be months before we use a model of this level of capability." Tibo from the codeex team at OpenAI simply responded, um, so who knows? We don't have access to mythos now, but Spud might be just around the corner and just as powerful. So, to come back to the question of the episode, Should we be scared of anthropics mythos? My answer is, of course, no. We should

be thoughtful. We should be diligent. We should use it as a moment to re-engage and recommmit to important and hard conversations. But fear serves no one. And even if we discover that this or a future model is genuinely worthy of concern, the right answer even then will not be to fall victim to fear. It will be to look at it, ask what we should do about it, and then go do that Thing. The interesting times continue, but for now, that is going to do it for today's AI daily brief. Appreciate you listening or watching as

always and until next time, peace.
