Anthropic released Fable 5, a consumer-accessible version of their internal Mythos AI model, which implements comprehensive safety guardrails to prevent misuse. These protections specifically block the model from generating content related to cybersecurity attacks and biological threats like viruses, ensuring the AI cannot be used to create harmful digital or biological weapons while still providing useful functionality.

Anthropic's Fable 5 Released!
Added:Bot released the um Fable 5, which is a version of Mythos, which is the AI model that a couple I think like a month ago um Anthropic was like, "We have created this destructive model that if we release to the public, everyone's going to die." And then it was like, "Is that real or like is that advertising? Like are we all going to die?"
But so Fable 5 is the first uh like consumer accessible iteration of Mythos. And I was not initially reporting on this when it came out like Monday.
>> When I saw Fable 5 announced, very excited, very interested. Um just to see what it could do, if it could do things that were better. And so I, you know, ran some tests and tried different things. But one of the most fascinating aspects of this is um just how much the protections are ramped up on it. So as you pointed out, one of the areas of course is cybersecurity. Um Anthropic, this is essentially Mythos but with big old handcuffs on. And of course I expected the cybersecurity area that it would not let you basically draft cyber attacks.
But it also is very aware of biological concerns, like creating viruses that could harm the population. So because of that, there are protections in place where it will not talk about cybersecurity stuff and it will not talk about biology stuff.
