They say its mythos like, without actually comparing it to Mythos (fair enough, it's not public) but the bar for a model to be mythos-like has to be that you can produce as many novel and high severity security vulns outlined in the Mythos redteam blog. I haven't seen any other lab produce a report like that yet. The proof is in the pudding.

It benches very similarly on the cyber benches Anthropic put out. That meets the bar.

Funny you say that, when the Mythos team have produced no proof either.

Not sure if the reports like this count? https://www.theregister.com/2026/04/22/mozilla_firefox_mytho...

I don't have strong opinion on that.

I believe they've stated that it would be too dangerous to release.

Just like OpenAI said GPT 2 was too dangerous to release?

There was just an article on this phenomenon today: https://news.ycombinator.com/item?id=47890235

They released a system card talking about how powerful it was. I don't think OpenAI did that with GPT 2.

		I mean, that's just part of the marketing too. OpenAI would've absolutely added a system card, they just weren't invented back in the GPT 2 era.
