Meta CEO Mark Zuckerberg said the company’s development of AI agents has progressed more slowly than expected despite a major restructuring and a sharp increase in infrastructure spending.

Speaking during an internal town hall on Thursday, Zuckerberg said development over the previous four months had not “accelerated in the way we expected,” according to a recording reviewed by Reuters.

He also acknowledged that Meta’s recent reorganization was not as clean as it could have been and that the company’s bets on the new structure had yet to deliver expected results.

The restructuring included cuts affecting 10% of Meta’s global workforce and the transfer of another 7,000 employees into initiatives focused on AI workflows. The layoffs and transfers together affected about 20% of the company’s workforce.

Zuckerberg said he expects Meta to begin seeing more significant benefits from its AI investments within the next three to six months. A company spokesperson declined to comment on the remarks.
