Ever wondered on a random Thursday afternoon what the chief executive of Meta might keep on his desk at the HQ?
I'm glad you asked.
Mark Zuckerberg posted a photo of his office desk to announce the release of Muse Spark Open, which lets you run a model with a fairly simple desktop setup. The company calls it "the most capable US open-weight model to date" and has teamed up with Apple to enable it to run on two M5 Ultra Mac Studios.
But never mind that; let's focus on the physical workspace.
Since this Muse is supposed to be so smart, I wanted to see how easily it could identify the objects on Zuckerberg's desk.
Two things immediately popped out to me: the black trinket on the right and the graffiti on the desk. Yeah, sure, there's whatever is on Zuckerberg's screen, which might provide a hint on what the CEO is working on as he steers a nearly $2 trillion company. But we don't want to know that, right?
Here's what the Muse agent caught—and what it needed help identifying:
-
Mark Zuckerberg's desktop screen: At a glance, he appears to be chatting with his Muse agent, Agrippa, named after the Roman general Marcus Vipsanius Agrippa.
-
A "Tamagotchi-style" virtual pet: Zuckerberg is asking Agrippa to build a software simulation of this pet, which Agrippa describes as a "chunky cream-and-gold 90s egg, blinking red LED, speaker grille, Feed / Train / Play buttons."
Zuckerberg has the latest and greatest Apple hardware: Two M5 Ultra Mac Studios are clearly visible.
My Muse said that the CEO is essentially asking for a: "software simulation of the Agrippa pet."
