Ep. 050 | Anthropic Built Something Too Dangerous to Release

Anthropic accidentally leaked the existence of their most powerful AI model ever and then confirmed it is real but too dangerous to release broadly.

The model is called Claude Mythos. It sits in an entirely new tier above Opus, internally called Capybara. According to Anthropic's own leaked draft blog post, Mythos dramatically outperforms Claude Opus 4.6 in coding, academic reasoning, and especially cybersecurity -- so much so that Anthropic says releasing it broadly right now could do more harm than good.

Michael and Frank break down what the leak actually revealed, why Anthropic is hitting the brakes on their own breakthrough, and what this moment means for small business owners who are still treating AI as something to look into later. The gap between businesses using AI and those sitting it out is already significant. When Capybara-level models hit the market, that gap becomes a canyon.

Frequently Asked Questions

What is Claude Mythos?
Claude Mythos is Anthropic's most powerful AI model to date, accidentally revealed through an internal data leak. It sits in a new model tier called Capybara -- above Opus -- and dramatically outperforms existing models in coding, reasoning, and cybersecurity.

Why isn't Anthropic releasing Claude Mythos publicly?
Anthropic says Mythos is currently far ahead of every other AI model in cybersecurity capabilities, creating serious dual-use risks. They are taking a deliberately slow rollout approach, currently testing with a small group of enterprise customers.

What does the Claude Mythos leak mean for small businesses?
It signals that the next tier of AI capability is real, ready, and already being tested by large enterprises. Small businesses that get fluent with current AI tools now will be far better positioned when these next-generation models become broadly available.

Something wild happened this week. Anthropic, the AI safety company, accidentally leaked details of a model they say is so powerful they're not sure they should release it.

SPEAKER_01 0:31

And I want to be clear, this wasn't a rumor. Their own draft blog post ended up in a publicly searchable data cache. Cybersecurity researchers found it, fortune broke the story, and Anthropic confirmed every detail.

SPEAKER_00 0:44

So we're not speculating. The company confirmed it, they built something called Claude Mythos, and they're saying, out loud, we have to be careful here.

SPEAKER_01 0:53

Right. And here's why that's significant. The model sits in a brand new tier above Opus, their current most powerful model. They're calling the tier Capybara. Larger, more intelligent than anything they've shipped, dramatically better at coding, academic reasoning, and cybersecurity.

SPEAKER_00 1:12

That last one is the key word, cyber security. Because their own leaked documents say Mythos is, quote, currently far ahead of every other AI model in cyber capabilities. And that's exactly why they're holding it back.

SPEAKER_01 1:26

To translate that for a business owner, imagine a tool that can find vulnerabilities in any software system faster and more accurately than any human security researcher alive. That's the double-edged sword. It's incredible for defense, it's terrifying for offense.

SPEAKER_00 1:43

So Anthropic is doing something we almost never see in this industry. They built the thing, it works. And they're saying, not yet. Let's think about this first.

SPEAKER_01 1:54

Which tells you something about where AI capability actually is right now. We're not talking about chatbots answering emails anymore. We're talking about models that can outperform human experts in specialized high-stakes domains.

SPEAKER_00 2:07

And look, I've been running businesses for a long time. The companies that survive disruption are the ones that see it coming. This is a signal. The next tier of AI isn't incremental. It's a category change.

SPEAKER_01 2:20

The gap between what's available to the public and what exists in a lab is wider than most people realize. Anthropic has this. Google has Gemini ultra variants that aren't fully public.

SPEAKER_00 2:35

What's already out there is not the ceiling. So what does this mean if you're running a small business right now? You're not going to get access to Mythos next week. But models at this level trickle down fast. What's classified today becomes available tomorrow.

SPEAKER_01 2:51

The practical move is to get fluent with what's available now, because the gap between businesses using AI well and businesses not using it at all is already significant. When Capibara level models hit the market, that gap becomes a canyon.

SPEAKER_00 3:05

We've been saying this for a while. The best time to start was last year, the second best time is today. When a company that builds AI is scared of its own model, that's not a reason to wait. That's a reason to get ready.

SPEAKER_01 3:16

One more thing worth noting. This leak also revealed Anthropic is planning a private CEO summit in Europe. They're selling enterprise access to this model right now to a select group of large corporations. The biggest companies in the world are already testing this.

SPEAKER_00 3:31

Which means if you're a small business competing against larger players, the window to be an early mover keeps shrinking. The enterprises are already at the table.

SPEAKER_01 3:40

The good news, AI tools built on the current generation are still genuinely powerful and massively underutilized by small businesses. You don't need mythos to get a serious edge.

SPEAKER_00 3:51

You need to actually use what's already there. Start there. We'll see you tomorrow.
