Anthropic just released the most powerful AI model the public has ever gotten its hands on. It's called Claude Fable 5 from the Mythos family, and it's a genuine step change in AI capabilities, not just another incremental update for most casual users. In use cases shared at launch, Stripe actually revealed that it used the family of models to migrate a 50 million line codebase in a single day, work that Anthropic says would normally take a team like two months. So that's the good news.
But here's the part that no one's saying out loud. The Fable and Mythos rollout might be the first real step toward AI that's not democratized. Because after June 22nd, your average Claude users will likely lose access entirely, leaving the true frontier power to big enterprises that have big API budgets. So, intelligence for the, but not for we. But that's not the only con to the massive pros that this model brings. What else is there to be worried about? Well, Anthropic can decide where this model is allowed to work. It quietly downgrades you without telling you. And it actually keeps every prompt input and output that you send it for 30 days. So yeah, we're breaking down today, not just the hype and the capabilities and the biggest upside, but also four big catches that should make every business leader nervous. And we're going to cover everything else in between as well. All right, let's get into it. So here's the big picture. Fable 5 is yes, definitely a capability shock. So Anthropic shipped the most powerful public Claude model yet, and the most capable the world has seen. So this is Fable 5 from the Mythos family. So if you're like, wait, Fable Mythos 5.1, isn't this the first Fable? Yes. All right, so essentially Fable 5 is the made for the public version of the also new Mythos 5, but with guardrails. So Mythos 5 is now available to the Project Glasswing elite there, but you have to be essentially invited to use the full Mythos 5 model, which is also released. But for everyone else, you have the Fable 5, which is the made for the public version with more guardrails. But even so, Fable 5 is a genuine step change. It's the biggest capability leap that Anthropic has shipped.
So the upside is clear and it's enormous. It executes real long complex work, not just better chat bots, right? And you can not only use this in, you know, Claude.AI and Claude Cowork and Claude Code and all of those things, but also on the API side. So the flexibility and the capabilities are a big step forward. It's enormous, but it arrives with four big catches, gated access, restrictions, a lack of transparency, and required data retention. For the most part, these are four new bottlenecks, roadblocks, or obstacles that we really haven't seen from a frontier model before, which is why today's show is going to be less about showing you hands on some of the capabilities and more about actually discussing the pros and the cons and the facts behind this new model. So on today's show, stick with me for the next 25ish minutes and you're going to learn why Fable is the most capable public Claude model ever released. You're going to know what the step change actually does across coding, science, and workflows. You're going to know those four catches, the shrinking access, usage restrictions, hidden downgrades, and data retention. And I'm going to let you know how business leaders should adopt this frontier model without getting burned. Come, well, two and a half weeks from now. All right, let's get into it.

All right, so let's talk Claude Fable 5 and Mythos 5, which I think are Anthropic's boldest and riskiest launches yet. So here's some of my thoughts. All right, and notice this model came out Tuesday. I decided not to do the show Wednesday because I wanted to actually spend some time on this.
