Anthropic has formally announced their most powerful model ever, one that makes Opus 4.6, just a couple of months old, feel of the past.

And yet, they're not releasing it to the general public. In fact, the entire discourse they're surrounding it with has some people feeling nervous or even scared.

Today we're going to unpack what is actually going on and whether that feeling of fear

is the right one or not. The AI Daily Brief is a daily podcast and video about the most

important news and discussions in AI. All right, friends, quick announcements before we dive in.

You can find a link from the main website or go to enterpriseclaw.a.i. We also have the most recent AI usage Pulse Survey live. This is now the third month that we've done this, and we're starting to see some really interesting longitudinal patterns. This will be live all week, and anyone who fills out the survey, which should just take a couple of minutes, we'll get access to the results before anyone else. Lastly, there's been so much going on that I haven't had a chance to give an update in Agent Madness for a while, but it is ongoing. We are in round three of voting, which is open until Thursday, April 9th, and you can find

that at Agent Madness.a.I. Now, today we are going to be focused exclusively on this new

announcement and discussion around Anthropics mythos. It is a discussion that even for AI people

is fairly breathless. Now, you might remember about a week or a week and a half ago, we had a leaked

blog post

talking about this new model that represented a step change in capability that was in fact

so powerful that it had pretty serious cybersecurity implications and would not be released

to the public, at least not in the normal way.

That model mythos was confirmed at the time by Anthropic, but without a lot of detail,

but now that detail has come.

We got an announcement about the Project Glasswing, which is their way of soft testing it with a

very selected number of partners, with an I-2 hardening it from a cybersecurity perspective,

an extensive cybersecurity capability review from Anthropics Red Team, and even a 244-page

system card. And before we get into all the
