Meta Platforms' stock slipped more than 3% Friday after seeing massive gains earlier this week fueled by the early success of the company's new AI agent, Muse.

Muse, launched two and a half weeks ago, has been sitting at the top of Apple's U.S. App Store since last Friday and has been downloaded more than 3.4 million times.

On Wednesday, Meta Chief Executive Mark Zuckerberg announced new ways for users to access their Muse in the future: by talking to it live and accessing it via Meta smartglasses and a new upcoming handheld device called "Muse Charm."

Its stock is up more than 30% since the start of the month.
