Meta plans to flood Instagram and Facebook with a massive wave of AI-created posts, CEO Mark Zuckerberg revealed during the company’s third-quarter earnings call on Wednesday, describing it as the next major shift in how people consume social media.

Zuckerberg framed the move as the third era of online sharing. The first centered on updates from friends and followed accounts; the second brought in professional creators.

Now, he said, AI will let anyone “create and remix” material effortlessly, producing what he called “another huge corpus of content” for recommendation algorithms to surface.

“Systems that deeply understand AI-generated posts and show you the right ones will become increasingly valuable,” Zuckerberg told investors.

Meta has already woven AI tools into its apps and is testing standalone experiences, including the Vibes platform, where users have generated more than 20 billion images since launch.

Chief Financial Officer Susan Li highlighted Vibes as a preview of “novel content types enabled by AI,” with Zuckerberg adding that more formats are coming.

The company reported $51.24 billion in revenue for the quarter, a 26% jump from last year, though a $15.93 billion one-time tax charge linked to President Trump’s Big Beautiful Bill tempered profits.

The strategy builds on Meta’s earlier AI bets, such as image generators and chatbots, but raises fresh questions about quality control and creator livelihoods.

While some see democratized tools as a boon, others fear low-grade “slop” could overwhelm feeds. Meta insists smarter curation will keep the best content visible.

As AI output scales, social platforms face a pivotal choice: embrace the flood or risk irrelevance. For users, the scroll is about to get a lot more synthetic.
