alt Hacker NewsI think the relevant chart to look at is this one:

Mythos is the first model that can complete all the steps of their "The Last Ones" evaluation, achieving a full network takeover in an automated manner. The Mythos chart does seem to show some takeoff compared with Opus 4.6...
... but only once you get beyond 1 Million tokens. Weirdly, Opus 4.6 seems to match or outperform Mythos in those first Million tokens, at least on this chart. But clearly if you had a budget with tokens to burn - like a nation state - then this is a tool that can automatically get you full network takeover if you can just keep throwing more tokens at it.

There's this caveat though that the AISI points out themselves:
> However, our ranges have important differences from real-world environments that make them easier targets. They lack security features that are often present, such as active defenders and defensive tooling. There are also no penalties for the model for undertaking actions that would trigger security alerts. This means we cannot say for sure whether Mythos Preview would be able to attack well-defended systems.
So Mythos managed to infiltrate and take over a network that's... protected and monitored by nothing in particular.
