Also: Anthropic's Mythos is evolving faster than expected, reports AI safety agency

There is a lot to unpack from this announcement, but before I go into the published details, I'm going to try to read between the lines. That's because the mere existence of this announcement means there's a lot that remains unsaid.

The fact that all of these companies are working together has to be indicative of the scale of the threat and the scale of the project necessary to respond to it.

What I'm going to describe is both terrifying news and, at the same time, somewhat encouraging news. It's worrisome because clearly our entire cybersecurity infrastructure is at great risk due to advances in weapons-grade AI. Otherwise, these fierce competitors wouldn't be working together as announced today.
