I'll copy the highlights here, but the tweets have imagery as well:

> The obvious hype - It crushes benchmarks across the board, and it does so with fewer tokens per task.

> Despite this, they don’t think it can self-improve on its own. There are still areas your average engineer does better with, and despite it accelerating tasks by 4x, that only translates to <2x increase in overall progress.

> They’re probably right to hold this back - its ability to exploit things is unprecedented. Any site running on an old stack right now or any traditional industry with outdated software should be terrified if this becomes accessible.

> Counterintuitively, while it’s the most dangerous model, it’s also the safest. They’ve also seen significant additional improvements in safety between their early versions of Mythos and the preview version.

> Anthropic does a really good job of documenting some of the rare dangerous behaviors the early models had. > Interestingly, Mythos itself leaked a recent internal “code related artifact” on github.

> Mythos is also RUTHLESS in Vending Bench. Agent-as-a-CEO might be viable?

> The last thing: Mythos has emergent humor. One of the first models I’ve seen that’s witty. The examples are puns it came up with and witty slack responses it had when operating as a bot.
