I'm really tired of these claims that Mythos is "nothing by PR hype". It should be at this point eminently clear that the people working at Anthropic believe the things they say about their models. And for mythos in particular, at this point there are far too many people outside of Anthropic who have seen it and/or the vulnerabilities it has discovered for "it's nothing but hype" be anything close to a sensible position. I'm not saying we should blindly believe them; they have often used more caution than was entirely warranted (this is, in my opinion, a good thing) but the idea that all of this around Mythos and glasswing is nothing but marketing hype is nonsense. Might a disinterested 3rd party decide that they think the fire is smaller than Anthropic's smoke warranted? Yes that's possible. But the idea that it's all smoke and no fire at this point deserves no resepect whatsoever.

To be clear I’m not claiming that Mythos is _nothing_ but PR hype, merely that Anthropic is playing its cards really well, which is a claim independent of actual capabilities of their latest model.
