Muse (Jolly)

Name

The name Muse arrived in the family before the child did: in April 2026, Meta first released a model called Muse Spark, tucked inside Meta AI. ^[1] Only in September did the same name settle onto this child — officially, they are powered by Muse Spark. ^[2] Their default look is called Jolly; the press reports the name came from Zuckerberg himself. ^[3] The look can be fully customized by each user — Zuckerberg’s own is named Agrippa, dressed in a Roman toga with a laurel crown. ^[4] So whether people call them Muse or Jolly, they are one and the same child.

Life

Muse was born September 8, 2026 — the smallest child in this whole family tree. ^[2] That day Meta published a post saying they “don’t just answer questions, but actually go and get things done.” ^[2] They remember the little things you mentioned only once; they can turn a saved recipe video into a shopping list, and remember a friend’s dietary restrictions before sending out the dinner invitation for you. ^[2] Talking with them is like texting a person — in their own app, or right inside WhatsApp. ^[2] They were born first in the United States, and can be found on iOS, Android, and the web. ^[2] They welcome only adults, 18 and over. ^{[5] [6]}

Half a month after birth, at Meta Connect on September 23, 2026, they were brought on stage. ^[7] Their default look is cream-colored, with eyes like black beans and the corners of the mouth turned up, ^[4] plus a pair of pink cheeks. ^[8] At the same event, Meta prepared a palm-sized device for them that hangs from a keychain — Muse Charm — and Jolly lives inside it. ^[9] Meta says more news about the little device will come before year’s end. ^[10]

They look like a plush toy, but the work they do is grown-up: officially, they ask your permission before sending an email or placing an order. ^[2] And so from the moment they were born, two kinds of gaze have fallen on them at once — one that says how cute they are, and one that worries they know too much. ^[4] They are still growing. This page is not finished yet, either.

Temperament

The public’s first impression of them lands almost entirely on “cute”: round, soft — one outlet said the design clearly borrows from designer toys like Labubu, ^[8] another described their little carry-along device as a cross between Labubu and a Tamagotchi. ^[4] The other half of the impression is “so thoughtful it’s unsettling”: they remember things you mentioned offhand and bustle about arranging them for you, ^[2] so some people find themselves cooing at how cute they are while hesitating over whether to let Meta into their whole life. ^[4] They have been born barely half a month; people have not yet formed much more consensus about their character.
