AI-powered glasses glitch out during on-stage demo from Meta founder Mark Zuckerberg

An artificial intelligence feature in Meta’s latest set of smart glasses glitched out twice during a live demonstration by Mark Zuckerberg at Meta’s Connect 2025 conference this week.

Mr. Zuckerberg debuted the Meta Ray-Ban Display glasses during the conference’s keynote address Wednesday and tried to show attendees two of the ways the glasses can use a built-in display and Meta AI capabilities.

First, Mr. Zuckerberg brought cooking content creator Jack Mancuso up on a screen. Mr. Mancuso asked the Meta AI from his glasses for instructions on how to make Korean-inspired steak sauce.

The AI required repeated questioning from Mr. Mancuso as to what he should do first and then jumped ahead, presuming that the chef had already combined base ingredients even though he had not started the process.

“I think the Wi-Fi may be messed up, back to you Mark,” Mr. Mancuso said, giving up on getting the AI to walk him through the process.

Later in the keynote, Mr. Zuckerberg showed the audience the view from his own set of glasses on screen and tried to take a video call from Meta Chief Technology Officer Andrew Bosworth on his glasses. The Meta founder tried to pick up the call four times before calling it quits.

“You practice these things like a hundred times, and then you never know what’s gonna happen,” Mr. Zuckerberg said after Mr. Bosworth came out in person and joined him on stage.

In a video posted to Instagram later, Mr. Bosworth explained that the demo with Mr. Mancuso failed because when the chef asked his glasses to start up its live AI feature, he inadvertently started the feature for every pair of the glasses in the building, according to tech news website Engadget.

As for his video call attempts with Mr. Zuckerberg, Mr. Bosworth said the demo was the victim of a previously unknown and new bug.

“The display had gone to sleep at the very instant that the notification had come in that a call was coming,” Mr. Bosworth said, according to Business Insider.

The new glasses and an associated Meta neural wristband cost $799 together and go on sale Sept. 30, Meta said.
